Hi,
I cant check combo value below. Where is the mistake?
Thanks
<script Language="JavaScript">
function validateR(){
var selectedCombobox=(form2.selectCombo.value);
if (selectedCombobox=='All') {
alert("Please select something");
return false;
}
return true;
}
</script><select name="selectCombo">
<option value="All">All</option>
<option value="Other">Other</option>
</select>
This basic example will force the user to select atleast 1 option from the selection list. Hope you had a great time! Enjoy coding...
