Sorting Select box with jQuery

Question

I have a select box on a form, which carries an incremental rel attribute. I have a function that can sort the options by thier .text() value, into alphabetcal order.

For future reference, the accepted answer is not complete if option has data or props (e.g. .prop('selected', true)). They will be removed after using .html().

The function below is probably not optimized but it's correctly working :

$.fn.sortChildren = function(selector, sortFunc) {
    $(this)
    .children(selector)
    .detach()
    .sort(sortFunc)
    .appendTo($(this));
};

$('select').sortChildren('option', function(a, b) {
    // sort impl
});
