MUI顶部选项卡的用法详解

来源：保捱科技网

MUI是一款最接近原生APP体验的高性能前端框架，它的比较重要的功能是：下拉刷新、侧滑导航、滑动触发操作菜单和顶部(底部)选项卡等。

最近用MUI做手机app应用的时候，遇到的小bug。顺便研究了一下这个tab-top-webview-main，这里给大家分享一下。

 <script type="text/javascript">
 mui.init({
 subpages:[{ //下边是初始化，然后这个页面显示我们将插入的页面
 url:"tab-top-webview-main.html",
 id:"tab-top-webview-main.html",
 styles:{
 top:"50px",
 bottom:"0px"
 }
 }]
 })

 url: "tab-top-subpage-1.html",

 }, {

 url: "tab-top-subpage-2.html",

 }],
 onChange: function(obj) {
 var c = document.querySelector(".mui-control-item.mui-active");
 if(c) {
 c.classList.remove("mui-active");
 }
 document.querySelector(".mui-scroll .mui-control-item:nth-child(" + (parseInt(obj.index) + 1) + ")").classList.add("mui-active");
 }
 });
 mui(".mui-scroll").on("tap", ".mui-control-item", function(e) {
 var wid = this.getAttribute("data-wid");
 group.switchTab(wid);
 });
 });
 mui.back = function() {
 var _self = plus.webview.currentWebview();
 _self.close("auto");
 }

3代码解释

var group = new webviewGroup("tab-top-webview-main.html", {
 items: [{
 id: "tab-top-subpage-1.html", //这是子页1的路径
 url: "tab-top-subpage-1.html",
 extras: {}
 }, {
 id: "tab-top-subpage-2.html", //这是子页2的路径
 url: "tab-top-subpage-2.html",
 extras: {}
 }]
 })

　　1、子页选项卡的超链接a的data-wid=""属性需要设置为对应子页选项卡路径。

<a class="mui-control-item mui-active" href="#item1mobile" rel="external nofollow" rel="external nofollow" data-wid="tab-top-subpage-1.html">
 推荐
</a>

　　2、这里，new webviewGroup("tab-top-webview-main.html",{}) 第一个参数需要传入一个页面的id。需要注意的是，这个页面id 就是我们包含顶部选项卡的页面，也就是当前我们这段js所在的页面

new webviewGroup("tab-top-webview-main.html", {}

　　3、 items数组中传入的是子页对应选项卡该导入的子页面的id，有几个子页就添加几个子页，中间用逗号分隔
