I tried googling but because of those bods who named their framework the same, I can't find what i need.

Can someone help me please, thanks..

here is what I have..

Code: 
document.prototype.getid = function(myid) {return this.document.getElementById(myid);};

so then all I have to type is getid('myid').value

at the moment when i use getid it throws an object expected error.


thanks 1DMF

You don't need to use prototype, or document, if you are simply wanting to create a global function. Simply create a global function:

Code: 
<html>
<head>
	<script type="text/javascript">

		[!]function getid(id) {
			return(document.getElementById(id));
		}[/!]

		window.onload = function() {
			alert(getid('wibble'));
		}

	</script>
</head>
<body>
	<div id="wibble"></div>
</body>
</html>

Hope this helps,

yeah I guessed that would be the easy option, but thought I'd try something new, Khat brought me the world of prototype and so thought I'd have ago.

is it possible with the prototype JS functionality and what would the syntax be?

If you use prototype then you can't simply use "getid()", you have to use "document.getid()" because you're adding the method to the document object.

ahh gotcha. although I tried document.getid() and still got an error, "object doesn't support this property or method". oh well I tried, I failed - lol.

I'm not sure why it didn't work when you referenced it properly. It should have. You might have had something else wrong with it.
