[Javascript] Function declaration

[Hakan M.]

A search on prefixing a function with [variable/indentifier]:: returned 
absolutely nothing for me, but Matt's assumption seem right.

Try this (pseudo)code to see if it works:
//---------------------
var oDiv = document.createElement('div');
oDiv.innerHTML = 'try clicking me';
function oDiv::onmousedown() {
	alert('mousedown!');
}
document.body.appendChild(oDiv);
//---------------------

My guess is:

function oDiv*::onmousedown**
*) oDiv is the object where you want to add a method/define a method
**) The method you wish to add/modify

But again I have to agree with Matt, I have never ever seen this syntax 
in JavaScript before (I've been developing complex javascript 
applications for the last couple of years) but as soon as someone find 
time to check the ECMAScript specs they will probably prove me wrong and 
give me a cone hat to wear in the n00b-corner.

In conclusion I'd like to say, on a personal note, that if the code is 
actually doing the exact same thing as in the example Matt provided, I 
see no reason to use yet another confusing way of doing this. But I 
guess it all comes down to preferred coding practice. :)

Regards,
Hakan
