HTML <form> autocomplete Attribute

The autocomplete attribute of the <form> element allows you to set whether the autocomplete for the form should be on or off. The web browser automatically fills the values if the autocomplete is on. This only happens if the user already entered values before.

Following is the syntax −

<form autocomplete="on|off">

Above, on | off values are to be set for autocomplete to appear or not. Set on if you want the browser to complete the entries based on previously entered values, whereas off doesn’t allow to complete the entries.

Let us now see an example to implement the autocomplete attribute of the <form> element −

Example

<!DOCTYPE html>
<html>
<body>
<h2>Points</h2>
<form action="" method="get" autocomplete="on">
   Player: <input type="text" name="player"><br>
   Rank: <input type="number" name="rank"><br>
   Points: <input type="number" name="pts"><br>
   <button type="submit" value="Submit">Submit</button>
</form>
</body>
</html>

This will produce the following output. Let’s say we previously entered some values in the form.

All of them would appear now since we have set autocomplete on −
