Hi,
I've got a small javascript problem and I'm kinda stuck. I'm using
classic ASP. I have a select box which is populated by a database
query and there is a buttom that when clicked it will move the selected
item from the first select box and move it to another select box:
document.form2.list.options[document.form2.list.options.length] = new
Option(count + 1 + ". " + name,company);
Then I want to remove it from the first select box:
document.form1.companies.options[document.form1.companies.selectedIndex] text = "";
But that just leaves an empty spot. I need to remove that spot
altogether and move all the other items up by one.
This is what I have:
for (i=document.form1.companies.options.length-1; i>0;
i--){document.form1.companies.options[document.form1.companies.selectedI ndex].value = i;
}
But this doesn't work.
Anyone have any ideas?
Thanks
Rob
