Control Form Completion
Description
There are times when you don't want the browser to fill out the form automatically.
We can use autocomplete attribute from form element to control this.
There are two allowed values for the autocomplete attribute: on and off.
The on value permits the browser to fill out the form
and is the default value.
Example
The following code shows how you can do this, using the autocomplete
attribute on the form element.
<!DOCTYPE HTML>
<html>
<body>
<form autocomplete="off"
method="post"
action="http://example.com/form">
<input name="fave" /> <input name="name" />
<button>Submit Vote</button>
</form><!-- w ww .ja v a2s.c o m-->
</body>
</html>
You can be more specific by applying the autocomplete attribute to individual input elements,
as shown in the following code.
<!DOCTYPE HTML>
<html>
<body>
<form autocomplete="off"
method="post"
action="http://example.com/form">
<input autocomplete="on" name="fave" />
<input name="name" />
<button>Submit Vote</button>
</form><!--from www. j av a 2 s.com-->
</body>
</html>
The autocomplete attribute on the form element
sets the default policy for the input elements in the form.
You can override that policy for individual elements.
In the code above, the attribute on the form element disabled autocomplete, but the same attribute applied to the first input element switches it back on.
The second input element, to which the autocomplete attribute has not been applied,
is subject to the form-wide policy.
