Question

Is there documentation that provides/explains all possible jQuery filter parameters allowed?

Some of the examples I have seen are :first and :last – are there any more?

Those are just the built in ones, though. You can actually create your own!

So if you wanted to get all <div> elements that satisfied a certain criteria through a filter, you could do:

$.expr[':'].big = function(e) {  
    return $(e).width() > 500;
};
$('div:big'); // would only select divs that are over 500 pixels wide
