各位大神,APP,设置底部菜单(mui-bar-tab)切换能链接上的网页,但是切换到首页的时候,顶部就不见了,增加tab,这是什么原因?
代码在此:
<script type="text/javascript" charset="utf-8">
//mui初始化
mui.init();
var subpages = ['about.html', 'index-dongtai.html', 'index-order.html', 'index-client.html'];
var subpage_style = {
top: '0px',
bottom: '50px'
};
var aniShow = {};
//创建子页面,首个选项卡页面显示,其它均隐藏;
mui.plusReady(function() {
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];
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
if(mui.os.ios||aniShow[targetTab]){
plus.webview.show(targetTab);
}else{
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');
}
});
</script>
