How do I implement onchange of <input type=“text”> with jQuery?

Question

has this API. What about ?

Answer 1

$("input").change(function () {
    alert("Changed!");
});

Answer 2

I would suggest using the keyup event something like below:

$('elementName').keyup(function() {
 alert("Key up detected");
});

There are a few ways of achieving the same result so I guess it's down to preference and depends on how you want it to work exactly.

Update: This only works for manual input not copy and paste.

For copy and paste I would recommend the following:

$('elementName').on('input',function(e){
 // Code here
});
