Hi,
The following should be all you need to handle select boxes.
(I used main as form name and myitemlist as select box name.)
Rythmist
1. Determine the text or value of selected item
var Item = document.main.myitemlist.selectedIndex;
var Result = document.main.myitemlist.options[Item].value;
or
var Result = document.main.myitemlist.options[Item].text;
2. Set the selected option (index = 0 to number of items in list)
document.main.myitemlist.selectedIndex = [index];
3. Determine how many items in list
var Result = document.main.myitemlist.length;
4. Set the text of a select option. (Remember to reload page)
document.main.myitemlist.options[index].text = "Text";
history.go(0);
5. Test for multiple Items selected in list
for (Count = 0; Count < document.main.myitemlist.length; Count++){
if (document.main.myitemlist.[Count].selected){
Temp += "Option " + document.main.myitemlist.options[Count].text +
" is selected\n";
}
}
alert(Temp);
