dynamic option list

[Philip WATTS]

I have generated a dynamic option list from an array using
elementCreate("OPTION")

I now wish to get an event to replace this list with a new one, but of
course currently, it simply adds them on to the end of the list.

Can I Delete or overwrite the options and if so by what method?

Many thanks

Try document.YourFormName.YourSelectName.options.lengt h=0;

This is not a built-in method of any widespread DOM.

You should get informed about what an event is. Probably you are
looking for event listener code triggered by an intrinsic event
handler.
but of course currently, it simply adds them on to the end of the list.

Try this:

<form action="...">
<select name="mySelect">
<option value="foo">bar</option>
...
</select>
<input
type="button"
value="Replace"
onclick="this.form.elements['mySelect'].options[0].text = 'foobar';">
<input
type="button"
value="Clear"
onclick="this.form.elements['mySelect'].options.length = 0;">
...
</form>
