This article explains how a website can disable autocomplete for form fields.
By default, browsers remember information that the user submits through input fields on websites. This enables the browser to offer autocomplete (i.e. suggest possible completions for fields that the user has started typing in) or autofill (i.e. pre-populate certain fields upon load).
These features can be a privacy concern for users, so while browsers can enable users to disable them, they are usually enabled by default. However, some data submitted in forms are either not useful in the future (e.g. a one-time pin) or contain sensitive information (e.g. a unique government identifier or credit card security code). A website might prefer that the browser not remember the values for such fields, even if the browser's autocomplete feature is enabled.
To disable autocompletion in forms, a website can set the autocomplete attribute to "off":
A website can either do this for an entire form, or for specific input elements in a form:
Setting autocomplete="off" here has two effects:
In some cases, the browser will keep suggesting autocompletion values even if the autocomplete attribute is set to off. This unexpected behavior can be quite puzzling for developers. The trick to really forcing the no-autocompletion is to assign a random string to the attribute, for example:
Since this random value is not a valid one, the browser will give up.
Modern browsers implement integrated password management: when the user enters a username and password for a site, the browser offers to remember it for the user. When the user visits the site again, the browser autofills the login fields with the stored values.
Additionally, the browser enables the user to choose a master password that the browser will use to encrypt stored login details.
Even without a master password, in-browser password management is generally seen as a net gain for security. Since users do not have to remember passwords that the browser stores for them, they are able to choose stronger passwords than they would otherwise.
For this reason, many modern browsers do not support autocomplete="off" for login fields:
This is the behavior in Firefox (since version 38), Google Chrome (since 34), and Internet Explorer (since version 11).
If an author would like to prevent the autofilling of password fields in user management pages where a user can specify a new password for someone other than themself, autocomplete="new-password" should be specified, though support for this has not been implemented in all browsers yet.

HTML forms are a key component to exchanging information between a user and the server. They are common in most visual programming languages, and are used in a variety of implementations on the Web. For example, forms allow users to perform tasks such as searching a Web site, providing feedback, or placing an order.
Microsoft Internet Explorer 5 and later includes an integrated feature called AutoComplete, which helps users quickly enter information into form fields. The AutoComplete innovation in HTML forms safely stores information entered into INPUT_text and INPUT_password fields. When a user submits a form, the name, value, and domain of the form component are encrypted for safekeeping. Storing the information helps users to complete single-line text fields. The next time that user visits a Web page and begins typing in a text field with the same name, the autocomplete attribute prompts an AutoComplete box to appear, providing the user with a list of previously used data.
An AutoComplete box is the primary interface for presenting data to the user. Until an entry in the AutoComplete box is selected, the data remains on the user's computer and is never accessible to a Web site.
AutoComplete in HTML forms provides the following advantages:
AutoComplete is an easy feature to incorporate into Web sites, and it provides a nonintrusive advantage for Web authors and users. For instance, when the user begins typing in an INPUT type=text field, the AutoComplete box presents a list of suggestions. The list of suggestions is saved in an encrypted store on the user's computer and is not accessible to Web sites. Because the user interface is integrated with the browser, it is streamlined with the Web page and transparent to the user. Individual Web sites do not need to make any changes to their content to use AutoComplete.
AutoComplete encrypts data for the AutoComplete box in a primary data store based on the NAME attribute of the INPUT type=text element. The information is shared among sites that include INPUT type=text elements with the same NAME attribute. Web authors do not have to change the NAME attribute of the field to select what data is displayed by AutoComplete. Instead, the author can use the VCARD_NAME attribute, which sets or retrieves the vCard value used by AutoComplete. vCard is a standards-based way to refer to common personal information.
The AutoComplete box appears discretely so as not to obstruct the view of the form. When the box is open, users can select information from the AutoComplete store. For example, a text field for a user's first name produces a list of previously submitted names.
The information is provided from previously submitted field values. It is specified through the vCard schema using the VCARD_NAME attribute, and this allows form fields to be completed without ever typing in a character. The vCard schema is created from the values specified in the Profile Assistant. The vCard schema is implemented when a Web site specifies one of the possible values that correspond to information in the Profile Assistant. The Profile Assistant can be accessed from Internet Explorer by choosing Internet Options on the Tools menu, selecting the Content tab, and then clicking the My Profile button in the Personal Information section.
The AutoComplete box appears when the following circumstances occur:
If the VCARD_NAME attribute is present, the AutoComplete box includes any information from the specified vCard item. Users can change the information listed in the AutoComplete box for text fields with the VCARD_NAME attribute.
Information for the AutoComplete box is provided by the following:
When a user enters information in an INPUT type=text element and submits a form, that information is encrypted and saved in the data store. If the values of the NAME or VCARD_NAME attributes match the data in the data store, that information is provided in the AutoComplete box. A user can quickly travel through an extensive form, because the requested information already is available and only needs to be selected.
AutoComplete is enabled by default in Internet Explorer. Web authors and users do not need to make any special accommodations to use this feature. When a user enters information in an INPUT type=text field and submits the form, the data is saved in the encrypted data store. The next time a user begins typing in an INPUT type=text field with the same name or VCARD_NAME attribute value, the AutoComplete box displays a list of suggestions.
The VCARD_NAME attribute draws information from the Profile Assistant as well as from previously entered information. The vCard schema draws information from the Profile Assistant based on the following schema names, each of which is represented by a field in the Profile Assistant.
The following example demonstrates how the VCARD_NAME attribute and the vCard.Email possible value are used to access and save the AutoComplete information. Rather than looking in the data store for the oEmail field name, the AutoComplete box is populated with values specified for the vCard.Email item.
Implementing AutoComplete is easy, but there may be times when either the user or the Web author does not want to use this feature. The AUTOCOMPLETE attribute allows Web authors to selectively disable the AutoComplete feature for a single INPUT type=text element or all INPUT type=text elements in a particular form. For example, by providing a value of off, a particular field or the entire form can be disabled. If a Web author does not want users to see the AutoComplete feature for a password field, the AUTOCOMPLETE attribute can be used to disable the feature for that single field, as in the following example:
In addition, if a Web author does not want users to see the AutoComplete feature for any field in a form, the AUTOCOMPLETE attribute can be used to disable the feature for the entire form.
You can enable AutoComplete by setting the value of the autocomplete property to an empty string.
To determine when a user updates the content of a field from the AutoComplete dialog box, use the onpropertychange event, rather than the onchange event, because the onchange event does not fire.
The AutoComplete Settings dialog box in Internet Explorer also allows users to enable or disable the AutoComplete box, as well as clear previously saved entries. For example, users can use the AutoComplete Settings dialog box in Internet Explorer to enable or disable the AutoComplete feature for forms and addresses, specify whether to include passwords when information is saved, and clear the existing data store.
The AutoComplete box provides several levels of security:
The first time a Web site is made aware of the new information is when the user selects one of the suggested entries and the data is entered into the field.
AutoComplete can be turned off using one of the following options:
The security measures provided for AutoComplete help protect passwords. The AutoComplete feature does not operate in the same fashion with password fields as with regular text fields. When a password is first entered, the user is prompted with the following options:
When the AutoComplete feature is set to save passwords, a password is automatically filled in when a known user name is provided, and the password and user name are stored by URL. When changing passwords, the user is prompted to save the new password.
AutoComplete provides a convenient and safe way for users to quickly complete forms, and for Web sites to enhance user experience on a page. User information saved in the AutoComplete data store is safeguarded, because Web sites cannot automatically fill in forms using the data store, and a login page facade cannot fool the browser into surrendering the information due to domain-specific security.

The autocomplete attribute was introduced as an unofficial HTML feature in Microsoft’s Internet Explorer, and was adopted by a number of other browsers. So there has been wide support for it for a long time, although its exact behavior wasn’t standardized. With HTML5, the autocomplete attribute is an official part of the specification.
The autocomplete attribute asks the browser to attempt autocompletion, based on user history. This is useful for personal details like name and email address — things the user is likely to have types into similar input fields on other web sites. The autocomplete feature is not able to provide the browser with a list of site-specific autocomplete options. For autocomplete behavior with site-specific suggestions, use the list attribute with the <datalist> element.
All the major browsers ignore the autocomplete="off" value for certain types of input fields. Internet Explorer and Edge ignore it for all password fields. Firefox ignores it for any field in a login form. Chrome ignores it any time the user has elected to let the browser remember form data. Safari ignores it for username, email, and password fields. Ignoring the autocomplete="off" value is done to enhance usability, and gve the user more control over autocomplete behavior. As a UX designer, you should follow their lead and use autocomplete="off" sparingly. There are are very few use cases in normal forms where it really makes sense to disallow autocomplete. In some complex apps, it makes sense to avoid accidental inputs, but with most standard forms there really is no reason for it.
Browsers use the name attribute in order to figure out what type of information an input field is asking for. So use standard, meaningful values for name. If you are asking for an address, use names like:
Don’t use clever or oddly specific names, as that makes it harder for the browser to provide autocomplete suggestions, and it can even lead to the browser trying to fill in the wrong values into the wrong inputs. (Have you ever had your browser fill your phone number into the zip code field? That was the fault of bad naming.)

Multiple selection feature for PrimeFaces jQuery AutoComplete has been a popular request and with 3.1, we’ve decided to bring it. Initial implementation was based on a simple input text and values were separated with commas but it didn’t match the coolness standard of PrimeFaces so we’ve decided to implement it Facebook style.
Here, we will use jQuery UI Autocomplete Control. To get the Data using AJAX, here we will try Handlers of ASP. Using Handlers against simple asp.net page is that, if we will use ASPX page then it will go through all the phases of page (nearly 1o) whereas Handler is faster than ASPX page.
The jQuery Autocomplete class adds a popdown menu of suggested values to a text field. The user can either click directly on a suggestion to enter it into the field, or navigate the list using the up and down arrow keys, selecting a value using the tab key. The values for the suggestion list are to provide as XML (by a PHP script, or similar).
Fancy Facebook-like dynamic inputs with auto complete & pre added values. If you have any comments or requests, please post it and I will try to include all the requested features in the upcoming release.
Make sure you check out the demo (or visit Apple.com) to see this awesome effect work. This example makes use of several techniques: MySQL (for the database), HTML/CSS for styling, PHP for retrieving the data and jQuery for the AJAX request.
To recreate the search suggest feature, we’re going to use jQuery and a small amount of PHP to query the server for search terms. To allow these two scripts to communicate, we’ll make use of AJAX — passing a string containing the search term from jQuery to PHP.
This jQuery Ajax autosuggest plugin has the usual functionality with a little extra flexibility: multiple instances, passing custom parameters, the id and the value are returned, keyboard-controlled, and a few others… Almost anything you need from an autosuggest plugin you can do with the built-in options!
TextExt is a plugin for jQuery which is designed to provide functionality such as tag input and autocomplete.

The HTML <form> element defines a form that is used to collect user input:
<form> .form elements . </form>
An HTML form contains form elements.
Form elements are different types of input elements, like text fields, checkboxes, radio buttons, submit buttons, and more.
The <input> element is the most important form element.
The <input> element can be displayed in several ways, depending on the type attribute.
Here are some examples:
You will learn a lot more about input types later in this tutorial.
<input type="text"> defines a one-line input field for text input:
<form> First name:<br> <input type="text" name="firstname"><br> Last name:<br> <input type="text" name="lastname"> </form>
This is how it will look like in a browser:
Note: The form itself is not visible. Also note that the default width of a text field is 20 characters.
<input type="radio"> defines a radio button.
Radio buttons let a user select ONE of a limited number of choices:
<form> <input type="radio" name="gender" value="male" checked> Male<br> <input type="radio" name="gender" value="female"> Female<br> <input type="radio" name="gender" value="other"> Other</form>
This is how the HTML code above will be displayed in a browser:
<input type="submit"> defines a button for submitting the form data to a form-handler.
The form-handler is typically a server page with a script for processing input data.
The form-handler is specified in the form's action attribute:
<form action="/action_page.php"> First name:<br> <input type="text" name="firstname" value="Mickey"><br> Last name:<br> <input type="text" name="lastname" value="Mouse"><br><br> <input type="submit" value="Submit"></form>
The action attribute defines the action to be performed when the form is submitted.
Normally, the form data is sent to a web page on the server when the user clicks on the submit button.
In the example above, the form data is sent to a page on the server called "/action_page.php". This page contains a server-side script that handles the form data:
<form action="/action_page.php">
If the action attribute is omitted, the action is set to the current page.
The target attribute specifies if the submitted result will open in a new browser tab, a frame, or in the current window.
The default value is "_self" which means the form will be submitted in the current window.
To make the form result open in a new browser tab, use the value "_blank":
Other legal values are "_parent", "_top", or a name representing the name of an iframe.
The method attribute specifies the HTTP method (GET or POST) to be used when submitting the form data:
or:
The default method when submitting form data is GET.
However, when GET is used, the submitted form data will be visible in the page address field:
/action_page.php?firstname=Mickey&lastname=Mouse
Notes on GET:
Always use POST if the form data contains sensitive or personal information. The POST method does not display the submitted form data in the page address field.
Notes on POST:
Each input field must have a name attribute to be submitted.
If the name attribute is omitted, the data of that input field will not be sent at all.
This example will only submit the "Last name" input field:
<form action="/action_page.php"> First name:<br> <input type="text" value="Mickey"><br> Last name:<br> <input type="text" name="lastname" value="Mouse"><br><br> <input type="submit" value="Submit"></form>
The <fieldset> element is used to group related data in a form.
The <legend> element defines a caption for the <fieldset> element.
<form action="/action_page.php"> <fieldset> <legend>Personal information:</legend> First name:<br> <input type="text" name="firstname" value="Mickey"><br> Last name:<br> <input type="text" name="lastname" value="Mouse"><br><br> <input type="submit" value="Submit"> </fieldset> </form>

This page is for users who are looking to delete stored Autocomplete data such as usernames, passwords, web addresses, and search queries. It is quite common for users to confuse Autocomplete with Autofill, but they are not the same. If you want to clear Autocomplete information in the address bar, see clearing the address bar history. To proceed, select your browser from the listing below and follow the steps.
Tip: You may press Ctrl+Shift+Del to access the Clear Recent History window.
Read First: Autocomplete does not function the same in Chrome as it does in other Internet browsers, thanks in part to Omnibox. The only way to clear all Autocomplete data in form fields is to clear your Autofill data as well. Some users may not want to do this, however, if they like to store address information using the Autofill feature. Therefore, we find the best solution is to clear unwanted entries individually, but both options are listed below.
Deleting Unwanted Entries Individually
Deleting All Autocomplete and Autofill Data
Read First: Autocomplete does not function quite the same in Safari as it does in other Internet browsers. The only way to clear all Autocomplete data in form fields is to clear your history data as well. This condition can be problematic as many users only want to clear one of the two. Therefore, we find the best solution is to clear unwanted entries individually, but both options are listed below.
Deleting Autocomplete and History
Read First: Autocomplete does not function quite the same in Opera as it does in other Internet browsers. The only way to clear all Autocomplete data in form fields is to clear your browsing history data as well. While you can delete a single page from the Opera browsing history, the address for that page will still be autocompleted if you type it in the address bar.
Note: If you've been using Opera for more than 4 weeks, you may want to select the beginning of time option in the drop-down menu.

Ever wish you could autocomplete the address fields in your WordPress forms? Autocomplete gives a more professional impression and makes the form filling process more convenient for your users. In this guide, we’ll show you how to autocomplete the address fields in your WordPress forms.
If you prefer not to watch the video, or need more instructions, then please continue reading for step by step instructions.
Autocomplete allows your visitors to easily fill out the address fields in your form. The autocomplete feature requires you to enable Google Places API on your form.
This makes form filling more convenient because it allows your site visitors to quickly select their address from suggestions generated in realtime as they type.
In fact, making it easier for your users to fill out your form is one of the best ways to encourage more form submissions.
It also helps to validate the information users enter, so that you don’t receive fake or wrong addresses. This will help you to cut down on spam form entries.
Now let’s take a look at the step by step guide to autocomplete the address fields in your WordPress forms.
Note: This plugin will add the entire address to a single text box, such as the first box in an address field.
The first thing you need to do is install and activate the WPForms plugin. Here’s a step by step guide on how to install a WordPress plugin.
Also, you’ll need to have a form created with the Address field added. See our tutorial on How to Create a Simple Contact Form as an example to get started.
We’ll be using a free plugin Address Autocomplete Using Google Place Api to autosuggest Google Place address when a user fills in the address field.
After installing and activating the plugin, go to Settings » Google Autocomplete page to configure plugin settings. You’ll now be asked to enter Google Places API Key.
The API key allows your website to connect with Google Maps and retrieve autocomplete suggestions from Google’s database in real time.
To create an API key, you’ll need to create a new project in your Google Developer Console account. To do this, click on the dropdown menu near the Google APIs heading.
You’ll now see a popup where you’ll have to click on the + icon to create a new project.
You’ll now be prompted to enter the project name. Enter the preferred name for your project and click Create. In a few seconds, you’ll be redirected to the new project page.
Then, you’ll be shown a list of Google APIs that you can enable for your project. Under Google Maps APIs, click on Google Place API Web Service.
Then, click Enable to proceed to the next step.
Now that you’ve enabled the API, the next step is to create credentials for it. Click Create Credentials.
In the Add Credentials to Your Project step, click the What credentials do I need? button.
You’ll now be given an API key. Copy the API key and paste it into your Google Autocomplete settings page in your WordPress dashboard.
You’ll also have to enable another API on your Google Developer Console. In the left taskbar, click Library. Under Google Maps APIs, click Google Maps JavaScript API, and then click Enable in the API overview page.
This API doesn’t need any further configuration.
In your web browser, navigate to the contact form page where you want to enable autocomplete address. Then right click on the address field and choose Inspect.
You can now see the source code of the address field.
You’ll have to find the name, ID or CSS values for your address field, in which you want to add autocomplete.
Below are the values in our example:
Copy at least one of those values and paste it in your autocomplete plugin’s settings page.
If you want to populate multiple address fields in different contact forms, make sure to separate them with a comma.
Then, click Save.
That’s it!
You’ve successfully enabled autocomplete in Your WordPress Forms.
With WPForms, the possibilities to customize your forms are endless.

В 1935 году легендарный Лоуренс Аравийский, подполковник британской армии, прослуживший более 20 лет в разведке на Ближнем Востоке, в авиации и в танковых войсках, вышел в отставку и поселился на родине в графстве Дорсет. Лоуренс любил скорость и был опытным мотоциклистом, ему принадлежали (в разное время) восемь мотоциклов «Броу Супериор» (англ. Brough Superior). 13 мая 1935 года Лоуренс ехал по проселочной дороге поблизости от своего дома на мотоцикле «Броу Супериор» SS100 (англ. Brough Superior SS100). Шлема на нем не было. Внезапно на дороге появились двое детей на велосипедах. Пытаясь избежать столкновения с ними, Лоуренс совершил резкий маневр, потерял управление и упал, получив травму головы. Шесть дней спустя Томас Лоуренс умер не приходя в сознание.
