html - How to disable autocomplete for all major browsers

How do you disable Autocomplete in the major browsers for a specific input and/or the complete form.

I found this solution:

However, this does not seem to work in all browsers. I've had problems in firefox for instance.

Edit:

My firefox issue has been resolved. That leaves the following: Can I disable autocomplete on a form or do I have to give every input autocomplete="off"

Answer

Autocomplete should work with the following types: text, search, url, tel, email, password, datepickers, range, and color.

But alas, you could try adding autocomplete='off' to your

tag instead of the tag, unless there's something preventing you from doing that.

If that doesn't work, you could also use JavaScript:

if (document.getElementsByTagName) {
    var inputElements = document.getElementsByTagName(“input”);

    for (i=0; inputElements[i]; i++) {
        if (inputElements[i].className && (inputElements[i].className.indexOf(“disableAutoComplete”) != -1)) {
            inputElements[i].setAttribute(“autocomplete”,”off”);
        }
    }
}

Or in jQuery:

$(document).ready(function(){
    $(':input').live('focus',function(){
        $(this).attr('autocomplete', 'off');
    });
});
