[Javascript] Wolter Zorn's Drag and Drop Script

[Terry Riegel]

Hello,

I am working with a drag and drop library written by Walter Zorn. He  
does some pretty cool things with his script. As I look at his code I  
first realize that I don't really understand OOP. I am trying to add  
a property to an object. Can anyone tell me why my addition isn't  
working?

---START---
dd.evt = function(d_e)
{
	this.but = (this.e = d_e || window.event).which || this.e.button || 0;
	this.button = (this.e.type == 'mousedown')? this.but
		: (dd.e && dd.e.button)? dd.e.button
		: 0;
	this.src = this.e.target || this.e.srcElement || null;
	this.src.tag = ("" + (this.src.tagName || this.src)).toLowerCase();
	this.x = dd.Int(this.e.pageX || this.e.clientX || 0);
	this.y = dd.Int(this.e.pageY || this.e.clientY || 0);

// My humble addition
this.terryriegel = 723;
// End my humble addition


	if(dd.ie)
	{
		this.x += dd.getScrollX() - (dd.ie && !dd.iemac)*1;
		this.y += dd.getScrollY() - (dd.ie && !dd.iemac)*1;
	}
	this.modifKey = this.e.modifiers?  
this.e.modifiers&Event.SHIFT_MASK : (this.e.shiftKey || false);
};
---END---




Thanks,
