最近用了下bootstrap,虽然好看，但是控件跟之前用的easyui相差很大，功能太少，不得不自己写。
花了几个小时把tabs控件扩展了下。下面是代码
页面代码：

var toolbar = $('<div class="btn-group"></div>');29
$("#tabtest").before(toolbar);30
Tabs.init({ selector: $("#tabtest"), close: true });31
for (var i = 1; i <= 40; i++) {32 (function (i) {33
toolbar.append($('<button type="button" class="btn btn-default">' + i + '</button>').click(function ()
{
Tabs.addtab({ title: "测试" + i, bindcode: i, content: i + " " + lwFW.dateHelper.toString(new Date(), "yyyy-MM-dd HH:mm:ss") });35 //Tabs.addtab({ title: "测试" + i, bindcode: i, url: "http://www.baidu.com" });36 }));37 })(i);38 };39 });

(jQuery);效果如下：
