I have gallery alike div container with many item di开发者_如何学Cvs inside. I want to select each fourth or in programming therms itemID % 4 == 0 item.

How can i do that with jQuery?

$('#select_id:nth-child(4n)')

Here is a demo

By using the :nth-child selector http://api.jquery.com/nth-child-selector/

In this way:

var div = $("div:eq(3)");

You could use filter -

$('div').filter(function(index) {
    return (index + 1) % 4 === 0;
})
