MUI顶部选项卡的用法详解

小云云asal: 2018-01-27 13:17:283436semak imbas

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。

1主页代码

<!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="external nofollow" rel="external nofollow" rel="stylesheet" />
    <style type="text/css">
      .d1{
        width: 100%;
        height: 50px;
        text-align: center;
        line-height: 50px;
        background-color: #CCCCCC;
      }
    </style>
  </head>
  <body>
    <p class="d1">我是p1,下面是插入的子页面</p> <!--我们将在这个p下边插入子页面-->
  </body>
  <script src="js/mui.min.js"></script>
  <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"
        }
      }]
    })
  </script>
</html>

2子页代码

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <title>Hello MUI</title>
    <meta name="viewport" content="width=device-width, initial-scale=1,maximum-scale=1,user-scalable=no">
    <meta name="apple-mobile-web-app-capable" content="yes">
    <meta name="apple-mobile-web-app-status-bar-style" content="black">
    <link rel="stylesheet" href="css/mui.min.css" rel="external nofollow" rel="external nofollow" >
  </head>
  <body>
    <p class="mui-content">
      <p id="slider" class="mui-slider mui-fullscreen">
        <p id="sliderSegmentedControl" class="mui-scroll-wrapper mui-slider-indicator mui-segmented-control mui-segmented-control-inverted">
          <p class="mui-scroll">
            <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>
            <a class="mui-control-item" href="#item2mobile" rel="external nofollow" data-wid="tab-top-subpage-2.html">
              热点
            </a>
          </p>
        </p>
      </p>
    </p>
    <script src="js/mui.min.js"></script>
    <script src="js/webviewGroup.js" type="text/javascript" charset="utf-8"></script>
    <script>
      mui.init();
      mui.plusReady(function() {
        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: {}
          }],
          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");
      }
    </script>
  </body>
</html>

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
