Dynamic HTML-Menu

[Konrad Mathieu]

Dynamically changing an HTML-menu:

function changeSelectMen u(v){
for(i=0;i<v;i++ ){
NewEntry = new Option(i+1,i,fa lse,false);
document.Testfo rm.Testmenu.opt ions[i] = NewEntry;
}
}

....works fine but:
When "v" is changed to a lower value, the old higher entries are still
visible.

How can one clear the options object before rewriting it?

Thanx and cheers,
Konrad

Sorry, missed out on the closing brace to end the for-loop:

function changeSelectMen u(v){
document.Testfo rm.Testmenu.len gth=0;
for(i=0;i<v;i++ ){
NewEntry = new Option(i+1,i,fa lse,false);
document.Testfo rm.Testmenu.opt ions[i] = NewEntry;
}
}
