Appending user inputs in javascript

Question

I have the below script, to show me the number version of the keys that are pressed, but as you can see here in jsfiddle I have no idea, why it is not working in fiddle. But, the I am just trying to have earlier inputs saved, because everytime I pressed a key, the previous number gets deleted and a new numbers corresponding the key pops up.

<script type="text/javascript">
function displayunicode(e){
var unicode=e.keyCode? e.keyCode : e.charCode
document.getElementById("op").innerHTML = unicode;

}
</script>
<form>
<textarea onkeyup="displayunicode(event);" ></textarea>

<div id="op"></div>
</form>

Change document.getElementById("op").innerHTML = unicode; to document.getElementById("op").innerHTML += unicode;

Use string concatenation (+=):

function displayunicode(e) {
    var unicode = e.keyCode ? e.keyCode : e.charCode
    document.getElementById("op").innerHTML += unicode;
}

DEMO: http://jsfiddle.net/KLV56/1/

Your fiddle was not working because you've added your script to onLoad event (see Figure below) that had hidden your function inside it. Use no wrap instead.
