jQuery 'input' event

Question

I\'ve never heard of an event in jQuery called input till I saw this jsfiddle.

Do you know why it\'s working? Is it an alias for keyup or s

Answer 1

oninput event is very useful to track input fields changes.

However it is not supported in IE version < 9. But older IE versions has its own proprietary event onpropertychange that does the same as oninput.

So you can use it this way:

$(':input').on('input propertychange');

To have a full crossbrowser support.

Since the propertychange can be triggered for ANY property change, for example, the disabled property is changed, then you want to do include this:

$(':input').on('propertychange input', function (e) {
    var valueChanged = false;

    if (e.type=='propertychange') {
        valueChanged = e.originalEvent.propertyName=='value';
    } else {
        valueChanged = true;
    }
    if (valueChanged) {
        /* Code goes here */
    }
});
