Mui怎么用代码切换选项卡高亮啊？

是这样，环境是当用户收到推送然后监听click事件，点击推送进入应用后应该自动跳转到消息选项卡

现在我可以切换选项卡的显示和隐藏，但是下方选项卡的高亮显示还是原来的，不知道怎么切换选项卡图标高亮的切换，用mui.fire(index,'gohome')也不行

这是选项卡

<nav class="mui-bar-dibu mui-bar-tab has-bottombar bottom-menu-fixed">  
            <a class="mui-tab-item" href="zhuangtai.html">  
                <span class="mui-icon iconfont icon-jihua1"></span>  
                <span class="mui-tab-label">状态</span>  
            </a>  
            <a class="mui-tab-item" href="zixiqiang.html">  
                <span class="mui-icon iconfont icon-xuexi"></span>  
                <span class="mui-tab-label">自习墙</span>  
            </a>  
            <a class="mui-tab-item" href="xiaoxi.html" id="xiaoxi">  
                <span class="mui-icon iconfont icon-xiaoxi2"><span class="iconfont icon-dian" id="xiaoxi-1" style="position: relative; left: -9px; top: -9px; color: #DD524D; display: none;"></span></span>  

                <span class="mui-tab-label">消息</span>  
            </a>  
            <a class="mui-tab-item mui-active" href="wode.html">  
                <span class="mui-icon iconfont icon-profile"></span>  
                <span class="mui-tab-label">我的</span>  
            </a>  
        </nav>

这是切换选项卡的部分，可以控制选项卡的显示和隐藏，但是选项卡上的高亮图标没变

function tabturn(targettab) {  
                var targetTab = targettab;  
                if (targetTab == activeTab) {  
                    return;  
                }  
                if (mui.os.ios || aniShow[targetTab]) {  
                    plus.webview.show(targetTab);  
                } else {  
                    var temp = {};  
                    temp[targetTab] = "true";  
                    mui.extend(aniShow, temp);  
                    plus.webview.show(targetTab, "fade-in", 300);  
                }  
                plus.webview.hide(activeTab);  
                activeTab = targetTab;  
                var defaultTab = document.getElementById("defaultTab");  
                //模拟首页点击  
                mui.trigger(defaultTab, 'tap');  
                //切换选项卡高亮  
                var current = document.querySelector(".mui-bar-tab>.mui-tab-item.mui-active");  
                if (defaultTab !== current) {  
                    current.classList.remove('mui-active');  
                    defaultTab.classList.add('mui-active');  
                }  
            }
