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 = {};
        var sub = plus.webview.create(subpages[i],subpages[i],subpage_style,{});
        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");
        }
    });
});
