      var $ = layui.$,table = layui.table,form = layui.form;

        var element = layui.element;

        element.on('tab(myTaskTabs)',function (data) {
            var index = data.index;
            var urlArr = [
                'myTaskTodoList.jsp',
                'myCreateTaskList.jsp',
                'myTaskDoneList.jsp',
                'myTaskList.jsp',
            ];
            layui.$("iframe[name='iframe" + index + "']").attr("src",urlArr[index]);

        })

   });
</script>

即动态修改 iframe 的src ,页面会重新加载。
