Details

In javascript 1.1, you are supposed to be able to clear a select list by setting
.options.length=0 (quote O'Reilly p671 of "JavaScript definitive guide", "If you
set options.length to 0, all options in the Select object are cleared").

However, if you execute the following code, you will get the (incorrect) error:

	JavaScript Error: Error: document.F.G.options.length is read-only

There are quite a few sites (including one I'm working on) that make dynamic
menus this way.

Here is some code:

<BODY ONLOAD="clearSelect();">
<HTML>
<SCRIPT LANGUAGE="JAVASCRIPT1.1">

function clearSelect() {
document.F.G.options.length=0;
}
</SCRIPT>
<FORM NAME="F">
<SELECT NAME="G">
<OPTION VALUE="FOO">FOO
</SELECT>
</FORM>
</HTML>
</BODY>
