Coding JQuery Plugins

TODO: Document JQuery plugin controls, especially those created for the LITTLED shared libraries. A lot of the existing functionality could be refactored to work better this way.

Plugins that return a value

$.fn.totalWidth() {
	var w = 0;
	this.each(function() {
		w += $(this).width();
	});
	return(w);
}

Then call the custom JQuery routine like this, which would return the total width of all the DIVS within the document:

$('div').totalWidth();

Some things to note about the example above:

• this refers to all the elements that match the selector.
• Within the $.each() function, $(this) refers to the current single element in the list of elements that match the selector.
• Declare and return the value outside the $.each() routine.
