mui开发APP教程之使用选项卡跳转子页面

首页HTML代码:

<!--主页面底部选项卡-->    <nav class="mui-bar mui-bar-tab">        <a id="defaultTab" class="mui-tab-item mui-active" href="html/index-sub-home.html">            <span class="mui-icon mui-icon-home"></span>            <span class="mui-tab-label">                首页            </span>        </a>        <a class="mui-tab-item" href="html/index-sub-classify.html">            <span class="mui-icon mui-icon-list"></span>            <span class="mui-tab-label" >                分类            </span>        </a>        <a class="mui-tab-item" href="html/index-sub-shopCart.html">            <span class="mui-icon iconfont icon-cart">                <span class="mui-badge" id="shopCartCount">2</span>            </span>            <span class="mui-tab-label">                购物车            </span>        </a>        <a class="mui-tab-item" href="html/index-sub-person.html">            <span class="mui-icon mui-icon-person"></span>            <span class="mui-tab-label" >                我的            </span>        </a>    </nav>

js代码：

mui.plusReady(function() {    //要切换的子页面    var subpages=[    'html/index-sub-home.html',    'html/index-sub-classify.html',    'html/index-sub-shopCart.html',    'html/index-sub-person.html'];    //子页面样式，这里只有主页的底部是公用的，所以距离底部51个px,距离顶部0个px    var subpage_style = {        top: '0px',        bottom: '51px'    };    var aniShow = {};    var self = plus.webview.currentWebview();    for (var i = 0; i < 4; i++) {        var temp = {};        if (i > 0) {            sub.hide();        }else{            temp[subpages[i]] = "true";            mui.extend(aniShow,temp);        }        self.append(sub);    }    //当前激活选项    var activeTab = subpages[0];    //选项卡点击事件    mui('.mui-bar-tab').on('tap', 'a', function(e) {        var targetTab = this.getAttribute('href');        if (targetTab == activeTab) {            return;        }        //显示目标选项卡        //若为iOS平台或非首次显示，则直接显示        if(mui.os.ios||aniShow[targetTab]){            plus.webview.show(targetTab);        }else{            //否则，使用fade-in动画，且保存变量            var temp = {};            temp[targetTab] = "true";            mui.extend(aniShow,temp);            plus.webview.show(targetTab,"fade-in",300);        }        //隐藏当前;        plus.webview.hide(activeTab);        //更改当前活跃的选项卡        activeTab = targetTab;    });    //自定义事件，模拟点击“首页选项卡”   即一加载的时候就显示默认的子页面，不然在点击选项卡之前，除了底部选项卡是一片空白    document.addEventListener('gohome', function() {        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');        }    });});
