remove option in a select

[specv]

Is it possible to remove an option in a select for both netscape and ie?

This code works whith ie but not with netscape :
my_listbox.options.remove(my_index)

Thanks

this should work

function removeSelectOption(objSelect, strValue)
{
	for (i=0;i<objSelect.options.length;i++)
	{
		if (objSelect.options[i].value == strValue)
		{
			objSelect.options[i] = null;
		}
	}
} //removeSelectOption

called like removeSelectOption(document.formName.SelectBoxName, ValueToDelete);

Setting the value to null will work but make sure that you lesson the loop on each iteration that you remove a option. Such as
function removeSelectOption(objSelect, strValue)
{
for (i=0;i<objSelect.options.length;i++)
{
if (objSelect.options.value == strValue)
{
objSelect.options = null;
i--;
}
}
} //removeSelectOption

This may not matter in you particular case, but I ran into this problem when trying to remove multiple options at once. Because every time you remove an option, the options array becomes 1 smaller. And if you try to set an option to null that no longer exists it will throw an error in certain browsers. Just something to keep in mind.
