select

[Alexandre Laplante]

Est-il possible en javascript de modifier les OPTION d'une balise SELECT a
partir d'un autre..? Donc la selection d'un premier choix changera la liste
du deuxieme.

Merci Alex...

Is this possible in javascript to modify the OPTION of an SELECT from an
other one..? So the first selection change the second option list.

Thank Alex...

Yes.
You can trigger on the change to the first select element using the
onchange event handler. You can then change the contents of the second
select element from this handler.

To change all the options of a select element (here referenced by
selectRef), you can do something like

var newOptions = ["option1","valu e1","option2"," value2"];

var optsRef = selectRef.optio ns;
while (optsRef.length > 0) { // Delete the current options
selectRef.remov e(optsRef[0]);
}
for (var i=0;i< newOptions.leng th;i+=2) {
selectRef.add(n ew Option(newOptio ns[i],newOptions[i+1]),null);
}

That is, use "selectRef.remo ve" to remove an option and
"selectRef.add( new Option(text,val ue),null)" to add a new option.
