1.建好子模板目录
2.导航代码
<nav class="mui-bar mui-bar-tab">
<a id="defaultTab" class="mui-tab-item mui-active" href="html/home1.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/home2.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/home3.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/home4.html">
<span class="mui-icon mui-icon-person"></span>
<span class="mui-tab-label" >
我的
</span>
</a>
</nav>
3.js代码
<script>
mui.plusReady(function() {
//要切换的子页面
var subpages=[
‘html/home1.html‘,
‘html/home2.html‘,
‘html/home3.html‘,
‘html/home4.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 = 1; 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‘);
}
});
});
