                var tabs = $.data(jq[0], 'tabs').tabs;
                for (var i = 0; i < tabs.length; i++) {
                    var tab = tabs[i];
                    if (tab.panel('options').id == id) {
                        return tab;
                    }
                }
                return null;
            },
            selectById: function (jq, id) {
                var tab;
                var tabs = $.data(jq[0], 'tabs').tabs;
                for (var i = 0; i < tabs.length; i++) {
                     tab = tabs[i];
                    if (tab.panel('options').id == id) {
                        break;
                    }
                }
                if (tab != undefined)  {
                
                    var curTabIndex = $("#tabs").tabs("getTabIndex", tab);
                    $('#tabs').tabs('select', curTabIndex);
                }

            },
            existsById: function (jq, id) {
                return jq.tabs('getTabById', id) != null;
            }
        });
    </script>
2.点击事件open方法
    function Open(text, url, id) {
        var tabId = ReplaceAll(url, '/','');
        var h = ComputGridHeight();
        if (url == "null" || url == "" || url == "") {
            return;
        }
        if ($("#tabs").tabs("existsById", tabId)) {
           
            $("#tabs").tabs("selectById", tabId);
        }
        else
        {
           
            if (url.indexOf("?") < 0) {
                url += "?_menuId=" + id;
            }
            else {
                url += "&_menuId=" + id;
            }
   
            $('#tabs').tabs('add', {
                id:tabId,
                title: text,
                closable: true,
                content: createTabContent(url, h),
                url: url
            });
