给bootstrap右边的菜单加上右键关闭

<ul class="rightmenu">
        <li data-type="closethis">关闭当前</li>
        <li data-type="closeall">关闭所有</li>
        <li data-type="closemenu">关闭菜单</li>
    </ul>

 <script type="text/javascript">
        $(‘.rightmenu‘).hide();
        $(document).click(function () {
            $(‘.rightmenu‘).hide();
        })
        $("#lr_frame_tabs_ul").on("contextmenu",function(e){
             var popupmenu = $(".rightmenu");
                l = ($(document).width() - e.clientX) < popupmenu.width() ? (e.clientX - popupmenu.width()) : e.clientX;
                t = ($(document).height() - e.clientY) < popupmenu.height() ? (e.clientY - popupmenu.height()) : e.clientY;
                popupmenu.css({left: l, top: t}).show();
                return false;
        })
        
        $(".rightmenu li").click(function () {
            if ($(this).attr("data-type") == "closethis") {
                var tabid = $("li[class=‘wms-frame-tabItem active‘]").attr(‘id‘).substr(7);// 获取当前激活的选项卡ID
