When looping over a group of items using jquery selectors is there a way to find out how many items there are on the collection?

Use the .length
property. It is not a function.
alert($('.class').length); // alerts a nonnegative number
You mean like length
or size()
?
If you are using a version of jQuery that is less than version 1.8 you can use the $('.class').size() which takes zero parameters. See documentation for more information on .size() method.
However if you are using (or plan to upgrade) to 1.8 or greater you can use $('.class').length property. See documentation for more information on .length property.
