How to select Listbox item via Javascript Jquery

I have a asp.net ListBox control on a page, that has nothing selected.

I will display a generated TABLE that includes a Javascript ONCLICK event to call a JS function to select that item.

Generated onclick event for the row:
onclick=\"addListbox('" + row.Channel_ID.ToString() + "')"

Open in new window


the JS:
<script type="text/javascript">
    function addListbox(selectedItem)
    {
        $("#ddChannels option[value='" + selectedItem + "']").attr("selected", true);
    }
</script>

Open in new window


Just for reference, the listbox:

<asp:ListBox ID="ddChannels" runat="server" CssClass="chzn-select" SelectionMode="Multiple"></asp:ListBox>

Open in new window


This ListBox is populated by the code behind...

But it doesn't seem to be working.

There are 2 ways of doing this thing.

<script type="text/javascript">
    function addListbox(selectedItem)
    {
        $("#ddChannels option[value=" + selectedItem + "]").attr("selected", "selected");
        
    }
</script>

Open in new window


Or

<script type="text/javascript">
    function addListbox(selectedItem)
    {
        $("#ddChannel").val(selectedItem);
        
    }
</script>
