- AttrGet() is used to get an attribute value for any page element that contains an ID attribute.
- It will work on dynamic IDs set by the .NET runat="server" server-side attribute.

Arguments:

	strTag (optional if the full ID is supplied):
		This is the the tag name of the element.
		It is used only if the supplied strIdPart argument doesn't match the ID of a page element.

	strIdPart (required):
		This is the ID or part of the ID of the element.
		If the full ID of a page element is supplied, the strTag argument is not used and can be set to null.
	
	strAttr (required):
		This is the attribute name to search for within the given strTag/strIdPart.
		The value that has been set for this attribute will be returned by the function.
	
	Example:
		AttrGet('div', 'Menu_Home', 'style.left');

It has been tested on and is compatible with:
	Microsoft Internet Explorer 6 and up
	Mozilla Firefox 2 and up
