jQuery Clearing DropDown

The fastest way to empty a select element: replace it with a shallow copy of itself.

function ClearOptions(id) {
    var selectObj = document.getElementById(id);
    var selectParentNode = selectObj.parentNode;
    var newSelectObj = selectObj.cloneNode(false); // shallow copy, no options
    selectParentNode.replaceChild(newSelectObj, selectObj);
    return newSelectObj;
