jQuery textbox change event

Question

Does text input element not have a change event  When I attach a change event handler to a text input it is not being fired  Keyup is fired  but keyup is not sufficient for detecting a change as there are obviously other ways of entering text into an input

There is no real solution to this - even in the links to other questions given above. In the end I have decided to use setTimeout and call a method that checks every second! Not an ideal solution, but a solution that works and code I am calling is simple enough to not have an effect on performance by being called all the time.

function InitPageControls() {
        CheckIfChanged();
    }

    function CheckIfChanged() {
        // do logic

        setTimeout(function () {
            CheckIfChanged();
        }, 1000);
    }

Hope this helps someone in the future as it seems there is no surefire way of acheiving this using event handlers...

The HTML4 spec for the  lt input gt  element specifies the following script events are available      onfocus  onblur  onselect  onchange    onclick  ondblclick  onmousedown    onmouseup  onmouseover  onmousemove    onmouseout  onkeypress  onkeydown    onkeyup   here s an example that bind s to all these events and shows what s going on http   jsfiddle net pxfunc zJ7Lf   I think you can filter out which events are truly relevent to your situation and detect what the text value was before and after the event to determine a change
