mui的选项卡js选中指定项

dom结构：在一定条件下想默认选中第二个选项卡

<div id="segmentedControl" class="mui-segmented-control mui-segmented-control-inverted mui-segmented-control-negative addressslider" style="border-bottom:1px solid #CCC;">
     <a class="mui-control-item mui-active" href="#item1">
        选择地址
     </a>
     <a class="mui-control-item" href="#item2" id="header2">
        新增地址
     </a>
</div> 

<div id="item1" class="mui-control-content mui-active" style="height:320px;">
    <div class="mui-scroll-wrapper">
        <div class="mui-scroll">
            第二个选项卡，有滚动
        </div>
        <!--<div class="mui-scrollbar mui-scrollbar-vertical" style="transition-duration: 500ms; opacity: 0;"><div class="mui-scrollbar-indicator" style="transition-duration: 0ms; display: block; height: 25px; transform: translate3d(0px, 0px, 0px) translateZ(0px); transition-timing-function: cubic-bezier(0.165, 0.84, 0.44, 1);"></div></div>
-->                        </div>
</div>
<div id="item2" class="mui-control-content" style="height:320px;">
     第二个选项卡
</div>

亲测可用

//模拟第二个选项卡点击
mui.trigger(document.getElementById("header2"),'touchstart');
mui.trigger(document.getElementById("header2"),'tap');

注意：

mui.trigger 第一个参数应该是dom对象，如果用jq需要转换成dom

依次触发touchstart  tap两个事件才可以
