This autocomplete attribute define that a form or input field should have autocomplete on or off.

When we define autocomplete is on, then browser automatically complete values the user has entered before

Note: It is also possible that autocomple attributes is "on" and "off" for specific input fields, or vice versa.

<!DOCTYPE html>
<form action="default.aspx" autocomplete="on">
Enter First name:<input type="text" name="fname" /><br />
Enter Last name: <input type="text" name="lname" /><br />
Enter Email id: <input type="email" name="email" autocomplete="off" /><br />
<input type="submit" />
<p>you fill all box and submit,then page will be reload then see how autocomplete work</p>
<p>See here that autocomplete is "on" for the form, but "off" for the e-mail field.</p>

Output of above declare code is

<form> novalidate Attribute

It is boolean attribute.

Specify that the form-data ( input) should not be validated when submitted.


<!DOCTYPE html>
<form action="default.axpx" novalidate="novalidate">
