Remove Option Elements From A Select Element Using JavaScript

  • submit to reddit
        Pretty simple, but here it is anyway.

// The DOM way.
var sel = document.getElementById('id_of_select');
for (i = sel.length - 1; i >= 0; i--) {

// The following code removes all options from a select element, but it only works 
// in Firefox, IE and Opera. It does not work in Chrome or Safari.
sel.length = 0;
