Question

I need to find an a-tag’s ID by its style.

My element have the class .sort.

The element’s style is programmatically added earlier in one of two get functions, and I have to find it in a third get function.

Answer 1

var result = $('a.sort[style="foo"]').attr('id');

Or if you don’t use inline styles(which you should not…):

var result = $('a.sort').filter(function(){
                            return $(this).css('foo') == valueYouAreSearching;
                        }).attr('id');

Note that searching by a style sounds awkward!
Just add the element a new class, and search for it by it’s new class name:

var result = $('a.sort.newClass').attr('id');
