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.

change function , but that needs to be done only if the the value is changed using the button . $("#address"). change will trigger if you perform any change in text field. If you want to trigger alert only when button click why you don't use alert inside button click function.
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 !=
We can listen to input value change with JavaScript with the addEventListener method. Then we can listen for changes in the value inputted by writing: const input = document. querySelector('input') input.
The HTML4 spec for the <input> 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

I have found that this works:
$(document).ready(function(){ $('textarea').bind('input propertychange', function() { //do your update here } }) If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
