使用Hbuilder的mui框架开发移动端非常便利、高效；
底部导航栏切换功能也是移动APP开发中必须实现的；
引入mui文件、下面会用到jquery，同时引进
<link href="css/mui.min.css" rel="stylesheet"/>
<script type="text/javascript" src="js/jquery.js" ></script>
<script src="js/mui.min.js"></script>
html代码：
<header class="mui-bar mui-bar-nav">
<a class="mui-action-back mui-icon mui-icon-left-nav mui-pull-left"></a>
<h1 class="mui-title">首页</h1>
</header> <nav class="mui-bar mui-bar-tab">
<a href="home.html" class="mui-tab-item mui-active" id="defaultTab">
<span class="mui-icon mui-icon-home"></span>
<span class="mui-tab-label">首页</span>
</a>
<a href="message.html" class="mui-tab-item">
<span class="mui-icon mui-icon-home"></span>
<span class="mui-tab-label">商城</span>
</a>
<a href="setting.html" class="mui-tab-item">
<span class="mui-icon mui-icon-home"><span class="mui-badge"></span></span>
<span class="mui-tab-label">购物车</span>
</a>
</nav>
在index的同级目录下创建首页，商城和购物车页面，home.html、message.html、setting.html作为分页；
js代码：
<script type="text/javascript">
//启用双击监听
mui.init({
gestureConfig:{
doubletap:true
},
subpages:[{
url:'home.html',
id:'MainViwe',
styles:{
top: '30px',
bottom: '51px'
}
}]
});
mui('.mui-scroll-wrapper').scroll({
deceleration: 0.0005 //flick 减速系数，系数越大，滚动速度越慢，滚动距离越小，默认值0.0006
});
//底部选项卡切换跳转
(function jumpPage(){
//跳转页面
var subpages = ['home.html','message.html', 'setting.html'];
var subpage_style = {
top: '44px',
bottom: '51px'
};
var Index=;
var actTab=subpages[Index],
tittle=document.querySelector('.mui-title');
var aniShow = {};//动画显示
//首次启动切滑效果
//当前激活选项
var activeTab = subpages[];
//选项卡点击事件
mui('.mui-bar-tab').on('tap', 'a', function(e) {
//修改对应分页
var targetTab = this.getAttribute('href');
$('#MainViwe').attr('src',targetTab);
//修改标题
tittle.innerHTML=this.querySelector('.mui-tab-label').innerHTML;
});
//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');
}
});
})()
</script>
切换分页的同时也切换了对应标题
分页home.html
<!doctype html>
<html> <head>
<meta charset="UTF-8">
<title></title>
<meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />
<link href="css/mui.min.css" rel="stylesheet" />
</head> <body>
<div class="mui-content"> <ul class="mui-table-view">
<li class="mui-table-view-cell"></li>
<li class="mui-table-view-cell"></li>
<li class="mui-table-view-cell"></li>
<li class="mui-table-view-cell"></li>
<li class="mui-table-view-cell"></li>
<li class="mui-table-view-cell"></li>
<li class="mui-table-view-cell"></li>
<li class="mui-table-view-cell"></li>
</ul>
</div>
<script src="js/mui.min.js"></script>
<script type="text/javascript">
mui.init()
</script>
</body>
</html>
效果：
