populate listbox using Javascript

I tried following :
document.getElementById("lsTest").Items.Add(new ListItem("Test"))
This gives following error message:
'document.getElementById(...).Items' is null or not an object
Also tried:
document.getElementById("lsTest").Add(new ListItem("Test"))
Result - Error Message:
'listitem' is undefined
Any idea?var o = document.createElement("option");
o.text = "test"
o.value = "test";
document.getElementById("lsTest").add(o);

Hi RA,
you can not add a listitem from javascript. A ListBox is rendered as
html SELECT element. So, you should add the items in javascript as if you
are adding to a SELECT element, which would be like follows
document.getElementById("lsTest").add(new Option("Text","Value"));

To remove an item from a textbox I tried;
document.getElementById("lsTest").remove(new Option("Testing","Testing"));
and
document.getElementById("lsTest").remove("Testing");
neither of above work. Both deletes very first Item in the listbox.
What I am doing wrong?
