I have a DropDownList (id: DropDownList1),
i want to get the items length by Jquery, but it not work, always
return 0.
My temporary solution is using classic javascript to do it, below is
the code.
<script type="text/javascript">
$(document).ready(function() {
//method 1:
var items = $("#DropDownList1 options");
alert(items.length); //Output: 0 = wrong
//method 2:
alert($("#DropDownList1 options").length); //Output:0 = wrong
//method 3:
alert(document.getElementById
('DropDownList1').options.length); //Output: 7 = Correct!
});
</script>
