为了不像官方演示的那样把所有tab页都塞在一个html里面造成卡顿，所以，将首页和各个tab页分开。
页面html结构如下：
<body> <header class="mui-bar mui-bar-nav" style="color:;"> <a href="#offCanvasSide" class="mui-icon mui-action-menu mui-icon-bars mui-pull-left mui-icon-contact"></a> <h1 id="title" class="mui-title" style="color:white;background-color:;">移动平台</h1> </header> <nav class="mui-bar mui-bar-tab"> <a id="defaultTab" class="mui-tab-item mui-active" href="homepage.html"> <span class="mui-icon mui-icon-home"></span> <span class="mui-tab-label">流程</span> </a> <a id="dotTab" class="mui-tab-item" href="gis.html"> <span class="mui-icon mui-icon-map"></span> <span class="mui-tab-label">网点</span> </a> <a id="caseTab" class="mui-tab-item" href="case.html"> <span class="mui-icon mui-icon-email"></span> <span class="mui-tab-label">案件</span> </a> </nav> </body>
JavaScript部分：
var menu = null,main = null; var showMenu = false; //mui初始化 mui.init(); var subpages = ['homepage.html', 'gis.html', 'case.html']; var subpage_style = { top: '45px', bottom: '51px', hardwareAccelerated: true//开启硬件加速 }; var aniShow = {}; mui.plusReady(function() { var self = plus.webview.currentWebview(); for(var i = 0; i < 3; 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]; var title = document.getElementById("title"); //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; } //更换标题 title.innerHTML = this.querySelector('.mui-tab-label').innerHTML; //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” 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'); } }); });
个人测试是可行的，欢迎指正啊。
