Remove item[i] from jQuery each loop

It would be better not to use $.each in this case. Use $.grep instead. This loops through an array in pretty much the same way as $.each with one exception. If you return true from the callback, the element is retained. Otherwise, it is removed from the array.

Your code should look something like this:

items = $.grep(items, function (el, i) {
    if (i === 5) { // or whatever
        return false;
    }

    // do your normal code on el

    return true; // keep the element in the array
});

One more note: this in the context of a $.grep callback is set to window, not to the array element.
