How to set focus int o next tab using tab key?

I want to create functionality when user use tab key for moving in to next tab. Every tab contains some text boxes. When user in last text box of tab 1 when it press the tab key, it will go into next text box of tab2. I am creating tab using plain HTML css and jQuery. I am not using tab functionality of jQuery UI but it is latest jQuery. The below is my HTML. I am creating tab using ul and li. How I move into next li when my tab in first text box. The tabs contains like dropdown, checkboxes, textboxes.

Note : I am not using tabindex due to some issue. I want to create using jQuery)

<ul class='tabs'>
        <li><a href='#tab1'>Tab 1</a></li>
        <li><a href='#tab2'>Tab 2</a></li>
        <li><a href='#tab3'>Tab 3</a></li>
      </ul>
      <div id='tab1'>
        <ul class= "set2"> 
            <li>  test 1<asp:TextBox runat="server"  ID="test1" /></li>
            <li>  test 2<asp:TextBox runat="server"  ID="test2" /></li>
        </ul>
      </div>
      <div id='tab3'>
        <ul class= "set2"> 
            <li>  test 3<asp:TextBox runat="server"  ID="test3" /></li>
            <li>  test 4<asp:TextBox runat="server"  ID="test4" /></li>
        </ul>
      </div>
      <div id='tab3'>
        <ul class= "set"> 
            <li>  test 5<asp:TextBox runat="server"  ID="test5" /></li>
            <li>  test 6<asp:TextBox runat="server"  ID="test6" /></li>
        </ul>
      </div>

script

// Wait until the DOM has loaded before querying the document
    $(document).ready(function(){
        $('ul.tabs').each(function(){
        // For each set of tabs, we want to keep track of
        // which tab is active and it's associated content
        var $active, $content, $links = $(this).find('a');

        // If the location.hash matches one of the links, use that as the active tab.
        // If no match is found, use the first link as the initial active tab.
        $active = $($links.filter('[href="'+location.hash+'"]')[0] || $links[0]);
        $active.addClass('active');
        $content = $($active.attr('href'));

        // Hide the remaining content
        $links.not($active).each(function () {
        $($(this).attr('href')).hide();
    });

        // Bind the click event handler
        $(this).on('click', 'a', function(e){
        // Make the old tab inactive.
        $active.removeClass('active');
        $content.hide();

        // Update the variables with the new link and content
        $active = $(this);
        $content = $($(this).attr('href'));

        // Make the tab active.
        $active.addClass('active');
        $content.show();

        // Prevent the anchor's default click action
        e.preventDefault();
    });
     });

$(document).on('keypress',function(e) {
 var keyCode = e.keyCode || e.which; 
 if (keyCode == 9) {       //if the key pressed was 'tab'...
    e.preventDefault(); 
    //how to focus on the next tab, 
    //remember to select the very first tab when you reach the last tab!
  }
