• MUI索引列表自定义----添加热门、最近等多个模块

    先看一下我们要实现的效果图

    效果图片

    首先我们需要引入的文件

    <link href="../css/mui.min.css" rel="stylesheet" />
<link href="../css/mui.indexedlist.css" rel="stylesheet" />
<script src="../js/mui.min.js"></script>
<script src="../js/mui.indexedlist.js"></script>

    自定义的CSS代码

    /*修改mui*/
html,body {height: 100%;overflow: hidden;}
.mui-bar {-webkit-box-shadow: none;box-shadow: none;}
.mui-icon-back:before, .mui-icon-left-nav:before{content: 'e460';color: #000;}
.mui-indexed-list-bar{width: 40px;background: #fff;}
.mui-indexed-list-bar.active{background: #fff;}
.mui-indexed-list-bar.active a{color: #ffd401;}
.mui-indexed-list-bar a{color: #ffd401;}
.mui-indexed-list-group{background: #fff;padding-top: 15px;padding-bottom: 15px;}
.mui-table-view-divider:after,.mui-table-view-divider:before,.mui-table-view:before{height: 0;}
.mui-indexed-list,.mui-indexed-list-search{border: none;}
/*添加class*/
.module-indexed-box{
    padding-right: 50px;
}
.module-address{
    padding:0 15px;
    padding-right: 0;
    font-size: 16px;
    color: #656566;
    background: #fff;
    height: 50px;
    line-height: 50px;
    margin: 0;
    position: relative;
}
.module-address span{
    display: block;
    border: 1px solid #d9d9d9;
    border-radius: 4px;
    height: 40px;
    line-height: 40px;
    margin-top:5px ;
    padding: 0 13px;
}
.trading-area,.recent-area{padding: 10px 15px;font-size: 0;}
.trading-area li{
    float: left;
    color: #999999;
    background: #f5f5f5;
    border: 1px solid #f5f5f5;
    font-size: 16px;
    padding: 5px 8px;
    border-radius: 16px;
    margin: 10px 15px 10px 0;
}
.trading-area li.active{
    background: #fff;
    color: #000;
    border: 1px solid #ffd401;
}
.recent-area li{
    display: inline-block;
    padding: 8px 14px;
    color: #8b8b8c;
    border: 1px solid #dbdbdb;
    border-radius: 4px;
    width: 30%;
    margin-right: 5%;
    font-size: 16px;
    text-align: center;
}
.recent-area li:nth-child(3n){margin-right: 0;}
.hot-area li{margin-top: 15px;margin-bottom: 15px;}

    自定义HTML代码

    <div class="module-indexed-box">
    <!--定位-->
    <div>
        <p data-group="定位" class="module-address module-limit-after">
            当前定位城市
            <span class="fr">成都·<em id="trading">双楠商圈</em></span>
        </p>
        <ul class="trading-area clear">
            <li class="active">双楠商圈</li>
            <li>骡马市商圈</li>
            <li>新会展商圈</li>
            <li>会展商圈</li>
            <li>神仙树商圈</li>
            <li>火车南站商圈</li>
        </ul>
    </div>
    <!--最近访问城市-->
    <div>
        <p data-group="最近" class="module-address module-limit-before">
            最近访问城市
        </p>
        <ul class="recent-area clear">
            <li>北京</li>
            <li>成都</li>
            <li>广州</li>
        </ul>
    </div>
    <!--热门城市-->
    <div>
        <p data-group="热门" class="module-address">
            热门城市
        </p>
        <ul class="recent-area hot-area clear">
            <li>北京</li>
            <li>上海</li>
            <li>成都</li>
            <li>广州</li>
            <li>深圳</li>
            <li>杭州</li>
            <li>重庆</li>
            <li>武汉</li>
            <li>西安</li>
            <li>长沙</li>
            <li>苏州</li>
            <li>南京</li>
            <li>大连</li>
            <li>沈阳</li>
            <li>青岛</li>
        </ul>
    </div>
</div>
<!--全部城市-->
<p data-group="定位" class="module-address">
    全部城市
</p>

    自定义的JS代码

    //当前城市商圈选择
mui('.trading-area').on('tap','li',function(){
    Array.from(this.parentElement.children).forEach(function(current){
        current.className = '';
    });
    this.className = 'active';
    document.getElementById('trading').innerText = this.innerText;
});

    页面完整代码（由于实例中城市太多，每一个字母我选择一个，减少代码量）

    原生JS–inedxed-list.js修改

    1. 将条件group && group.length == 1 修改为 group（在inedxed-list.js的85行）

      原因：由于添加的模块一般都是热门等汉字，此处字符串的长度就不完全是1所以要修改，从而使其触发定位函数。

    2. 将self.el.bar.offsetHeight - 40修改为 self.el.bar.offsetHeight - self.el.search.offsetHeight（在inedxed-list.js的57行）

      原因：此处代码是用来计算我们右侧导航条中每一个字母所占高度，此处mui源代码将搜索框的40px的高度固定的计算进去了，所以如果不修改，会导致导航始终错误，采用修改后的方式是不会影响其他，搜索框存在与否计算都是正确的。

    3. 如果不要搜索栏，就要将self.bindSearchEvent();禁止（在inedxed-list.js的174行）

      原因：如果我们不需要搜索，绑定事件就会报错，此处如果要搜索我们就放开代码，不需要就禁止，不影响其他代码的执行。
