[jQuery] custom selecters

[Tom Shafer]

Hi, i need to be able to find all elements with a div id of something
like divname plus some randmom number, each div id will be like this,
so something like divname324 or divname453

so how can I select all divs with a name divname plus some random
numbers

$("#divname + random number").ajaxForm({
        target: '#commentFormOutput',
        success:   processcommentForm
});

Thanks
