How to count the number of listitems in an asp.bulletedlist with JavaScript
- by Andy5
Hi
I have an asp:bulletedlist control, which sits inside a div tag, and I need to count the number of list items inside the control. Searching the internet, and noting the fact the html given back by the items is a list i.e. <li>, I thought I could use an example of:
var listcontrol = document.getElementById('BulletedList1');
var countItems = listcontrol.getElementByTagName('li').length;
However, when I do this, it throws and error saying that no object exists for this control.
So, my problem is, and because I must do this clientside because I want to use this to set the height of the div tag, is how do you count the number of items inside a asp:bulletedlist control with javascript?
