[Javascript] deleting all options

[Peter Brunone]

Can you still set options.length = 0?

Also, innerHTML = "" comes to mind (this might possibly be fastest, though not supported by earlier browsers)...

you can use

// get reference to element
var element = document.getElementById("mySelect");
// remove all children of element
while (element.firstChild) {
element.removeChild(element.firstChild);
}

As you presumably already have a variable reference to the select, adjust
accordingly.

The while loop there is a general purpose way of removing all the child
nodes of any element, so depending on your needs, you may find it useful
to move it into a function.

HTH,

Nick.
