adding option to select ??

[sebs]

here what i'm using to populate an selectbox

function populate(index){
	document.frm.subCat.options.length = 0;
	for(x=0;x<subArray[index].length;x++){
		var newOption = document.createElement("OPTION");
		newOption.value = subArray[index][x][0];
  		newOption.text = subArray[index][x][1];
		document.frm.subCat.add (newOption);
		}

ok, i got it to work but in nn
if there one option to begin with,
it does not get bigger

here's my new code:

function populate(index){
	document.frm.subCat.options.length = 0;
	for(x=0;x<subArray[index].length;x++){
		var newOption = new Option(subArray[index][x][1],subArray[index][x][0],false,false);
		document.frm.subCat.options[x] = newOption;
		}
	}

This is what I've been doing...

document.myForm.mySelect.options[document.myForm.mySelect.options.length] = new Option(myOptionText, myOptionValue);

But the only thing I'm finding at W3C, is to actually edit the HTML, and not treat the select as an dynamic object.

var myNewOption = document.createElement("option");
var myNewOptionText = document.createTextElement(myOptionText);

myNewOption.setAttribute("value", myOptionValue);
myNewOption.appendChild(myNewOptionText);

document.myForm.mySelect.appendChild(myNewOption);

I have no idea if that code works, I haven't tested it. I would hope that the ECMA standard would have a shortcut to work with form elements, but I don't know any good documentation on the ECMA standards, just their mapping to the W3C DOM. And I can understand the W3C not suggesting a way to edit options that would undermind the DOM.
