Move an item up/down a select

I'm wondering if it's possible to change the order of things in a select control without having to totally rebuild it?

Is there a javascript function where I can cha开发者_如何学运维nge the "index" of a specific option in the select?

Thanks

Sure, just find the two elements in jQuery (by their IDs or whatever), so you have two objects and then use before() on them

var o1=$("#opt1");
var o2=$("#opt2");
o2.insertBefore(o1);

Try using Array.splice

// Remove the option from the list:
var option = selectElement.options.splice(indexOfOptionToRemove,1);

// and put it back in at the new index:
selectElement.options.splice(indexOfNewOptionPosition,option);
