Question

Is there a magic jQuery selector that can select labels of input fields?

like $('#myinput').getLabel() or something?

or do I really have to use $('label[for="myinput"]') ?

Answer 1

You can always define it as a jQuery extension:

$.fn.getLabel = function () {
    var name = this.attr('name');
    if (!name) {
        // No id, so we can't find the label
        return $();
    }

    return $('label[for="' + name+ '"]');
};

(You might also want to handle possible "s in the id somehow)
