I want to run a function when a HTML <input/> tag changes. How do I do this? There are some answers for this but they are all in jQuery and I want plain javascript. Can someone give me a simple example? Thanks!

I want the input to be a type as text:

<input type=text id=change>

You can use the input event. This will trigger not only on key up and paste, but also other text modification events such as drag & drop.

change.addEventListener(input, function (e) {

    alert(this.value);

});

<input type=text id=change>
