How to get the selected value from ajax.net ComboBox through javascript

Question

Hello everyone, I need to get the selected value from an ajax.net combobox throught javascript so that I can do some client side validation.

What's the best way to do this? Thanks,

---

I've been able to get the value with this:

var combo = $get('ddlComarcas');
var comboHidden = $get('ddlComarcas_HiddenField');
var o4 = combo.getElementsByTagName('li')[comboHidden.value].childNodes[0];

alert('"' + o4.data + '"');

But I still need to trim the value from o4.data. Anyone can point how to do that visual studio 2008 jquery?

Answer 1

You can use jQuery or just use DOM:

jQuery:

var selection = $('#selectID').val();

DOM:

var selection = document.getElementById("selectID").value;

asp.net -> server side

javascript -> client side
