Javascript 选项卡未正常激活

Question

我有三个选项卡，它们的 active/inactive class 来自 javascript 代码。但是当我点击第二个或第三个选项卡时，它会移动到第一个选项卡。查看我的代码

$(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();
            });
        });
    });

另见 html 相同

<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，它都会再次移动到第一个选项卡。

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();

        }
    }

三个标签服务器点击代码：-

protected void ddlSortOrder_SelectedIndexChanged(object sender, EventArgs e)
    {
        using (SqlConnection conn = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["DefaultCSRConnection"].ConnectionString))

我不是 100% 确定，但我认为你应该参考 e.target 而不是 this:

$(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) {
            e.preventDefault();
            $active.removeClass('active');
            $content.hide();
            $active = $(e.target);
            $content = $(location.hash);
            $active.addClass('active');
            $content.show();
        });
    });
});

您还应该使用 e.preventDefault() 来停止默认的点击事件。就风格而言，我不建议使用 $ 作为变量，太接近 jQuery $ 用法而不是惯例。
