Form autocomplete attribute

HTML DOM Form 对象

Definition and Usage

autocomplete Set or return the value of the autocomplete attribute in the form.

After enabling auto-complete, the browser will automatically complete values based on the user's previous inputs.

Tip: You can set the form to "enable" auto-complete and set the specific input field to "disable", and vice versa.

Tip: In some browsers, you may need to enable the auto-complete feature to work properly (check the "Preferences" menu in the browser menu).
