Definition and Usage
The autocomplete attribute specifies whether or not an input field should have autocomplete enabled.
Autocomplete allows the browser to predict the value. When a user starts to type in a field, the browser should display options to fill in the field, based on earlier typed values.
Note: The autocomplete attribute works with the following <input> types: text, search, url, tel, email, password, datepickers, range, and color.
Browser Support
The numbers in the table specify the first browser version that fully supports the attribute.
| Attribute | |||||

Tip: In some browsers you may need to activate an autocomplete function for this to work (Look under "Preferences" in the browser's menu).
Differences Between HTML 4.01 and HTML5
