Can jQuery check whether input content has changed?

Question

Is it possible to bind javascript (jQuery is best) event to \"change\" form input value somehow?

I know about .change() method, but it does not trigger

Answer 1

Since the user can go into the OS menu and select paste using their mouse, there is no safe event that will trigger this for you. The only way I found that always works is to have a setInterval that checks if the input value has changed:

var inp = $('#input'),
    val = saved = inp.val(),
    tid = setInterval(function() {
        val = inp.val();
        if ( saved != val ) {
            console.log('#input has changed');
            saved = val;
    },50);

You can also set this up using a jQuery special event.
