Detecting Browser Autofill

Question

How do you tell if a browser has auto filled a text-box? Especially with username & password boxes that autofill around page load.

My first question is when does

Answer 1

My solution:

Listen to change events as you would normally, and on the DOM content load, do this:

setTimeout(function() {
    $('input').each(function() {
        var elem = $(this);
        if (elem.val()) elem.change();
    })
}, 250);

This will fire the change events for all the fields that aren't empty before the user had a chance to edit them.
