Loop through all elements with class 'blah' and find the highest id value

Question

I have a bunch of elements like:

..

I want to loop through all of them and get the highest

Answer 1

I would do:

var max = 0;
$(".blah").each(function(){
    num = parseInt(this.id.split("-")[1],10);
    if(num > max)
    {
       max = num;
    }
});

Most people would do this way.
