JavaScript Error: Microsoft JScript runtime error: Object expected

Below is the "truncated" code for an Ajax TabContainer I'm using for my web page. I need to find the tab index for the container in a JavaScript function, however I continue to get the error message "Microsoft JScript runtime error: Object expected" when this line of code is called in the JavaScript:

        function doValidate() {
            var tabIndex = $('#tabs_header span.ajax_tab_active').index()

If I comment out the "var tabIndex..." part I do not get the error, so I'm wondering if someone can tell me what is going on here. Below is the code for the tabContainer. I've "truncated" because it is a very large form with over 12 text box inputs. Both tabs represent two different methods of doing a search. By clicking on the "Search" button, the doValidate() method is the first action called, before the site even goes into the code behind. Also, I receive the same error message on the same line of code no matter which tab is active. 

    <asp:TabContainer ID="AdvOrBasicSearch" runat="server" ActiveTabIndex="0">
    <div id="tabs_header">
        <span id="tab1" class="ajax_tab_active">
        <asp:TabPanel ID="basicSearch" runat="server" HeaderText="Basic Search">.../asp:TabPanel>                

        </span>
        <span id="tab2" class="ajax_tab_active">
        <asp:TabPanel ID="advSearch" runat="server" HeaderText="Advanced Search">...</asp:TabPanel>
        </span>
    </div>
    </asp:TabContainer>

I found the answer to this question very quickly. I needed to create a JS variable that was the the tabContainer itself. Then, I just needed to go inside and grab the _activeTabIndex property value. Below is the altered code

        function doValidate() {
            var tabIndex = $find("AdvOrBasicSearch");
            var i = tabIndex._activeTabIndex;
