Javascript标签未正确激活

我有三个标签，其活动/非活动类来自javascript代码。但是，当我单击第二个或第三个选项卡时，它将移至第一个选项卡。看我的代码

$(document).ready(function () {
        $('ul.tabs1').each(function () {
            var $active, $content, $links = $(this).find('a');
            $active = $($links.filter('[href="' + location.hash + '"]')[0] || $links[0]);
            $active.addClass('active');
            $content = $($active[0].hash);
            $links.not($active).each(function () {
                $(this.hash).hide();
            });
            $(this).on('click', 'a', function (e) {
                $active.removeClass('active');
                $content.hide();
                $active = $(this);
                $content = $(this.hash);
                $active.addClass('active');
                $content.show();
            });
        });
    });

另请参见html的相同内容

<ul class='tabs1'>
            <li><a href='#tab1' id="allNews" runat="server" onserverclick="allNews_ServerClick">All News</a></li>

            <li><a href='#tab2' id="forNgo" runat="server" onserverclick="forNgo_ServerClick">For NGO</a></li>
            <li><a href='#tab3' id="fromNgo" runat="server" onserverclick="fromNgo_ServerClick">From NGO</a></li>
        </ul>

每当我单击second或third选项卡时，它就会再次移至第一个选项卡。

回发页面加载代码：-

 protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            HtmlAnchor HA = new HtmlAnchor();
            HA.ServerClick += new EventHandler(allNews_ServerClick);

            HtmlAnchor HA2 = new HtmlAnchor();
            HA2.ServerClick += new EventHandler(forNgo_ServerClick);

            HtmlAnchor HA3 = new HtmlAnchor();
            HA3.ServerClick += new EventHandler(fromNgo_ServerClick);

            BindNews();

        }
    }

三个标签中的serverclick代码：-
