Carpicker

HTML

选择品牌、车系、车型下拉框有三种形式

• 品牌、车系、车型共用一个下拉框
• 品牌、车系共用一个下拉框，车型单独使用一个下拉框
• 品牌、车系、车型各自使用下拉框

<!-- 品牌、车系、车型共用一个下拉框 -->
<div class="athm-select" id="js-select-simple" data-toggle="carpicker">
  <div class="athm-select__selected" data-select-picker>
    <span class="athm-select__text" data-select-value>选择品牌</span>
    <span class="athm-select__icon">
      <i class="athm-iconfont athm-iconfont-arrowdown"></i>
    </span>
  </div>
  <div class="athm-select__option" data-select-dropdown>
    <div class="pop-wrapper">
      <!-- 区别主要在这里，剩下的工作就交给了样式实现 -->
      <div class="brand" data-select-brand></div>
      <div class="series" data-select-series></div>
      <div class="spec" data-select-spec></div>
    </div>
  </div>
</div>

<!-- 品牌、车系共用一个下拉框 -->
<div class="athm-select" id="js-select-brand" data-toggle="carpicker">
  <div class="athm-select__selected" data-select-picker>
    <span class="athm-select__text" data-select-value>选择品牌</span>
    <span class="athm-select__icon">
      <i class="athm-iconfont athm-iconfont-arrowdown"></i>
    </span>
  </div>
  <div class="athm-select__option" data-select-dropdown>
    <div class="pop-wrapper">
      <div class="brand" data-select-brand></div>
      <div class="series" data-select-series></div>
    </div>
  </div>
</div>

<!-- 单选品牌下拉框 -->
<div class="athm-select" id="js-select-brand2" data-toggle="carpicker">
  <div class="athm-select__selected" data-select-picker>
    <span class="athm-select__text" data-select-value>选择品牌</span>
    <span class="athm-select__icon">
      <i class="athm-iconfont athm-iconfont-arrowdown"></i>
    </span>
  </div>
  <div class="athm-select__option" data-select-dropdown>
    <div class="pop-wrapper">
      <div class="brand" data-select-brand></div>
    </div>
  </div>
</div>

JavaScript

因为选择品牌、车型、车系涉及到数据来源及数据结构，所以在调用的时候增加了一些配置项

• 首页，针对不同数据来源及数据结构，我们需要自己写方法获取数据及处理数据结构
• 在选择品牌及车系之后执行下一步的方法

$('#select').carpicker(options);

var dataCar = {
  getBrandData: function() {
    var carBrand = [];
    brandSereisData.forEach(element => {
      var item = {
        'id': element.I,
        'name': element.N,
        'letter': element.L,
        'list': element.List
      }
      carBrand.push(item)
    });
    return carBrand;
  },
  getSeriesData: function(key, callback) {
    var carSeries = [];
    brandSereisData.forEach(element => {
      if (element.I == key) {
        element.List.forEach(ele => {
          var item = {
            'id': '',
            'name': '',
            'list': [],
            'brandId': key
          };
          item.id = ele.I;
          item.name = ele.N; 
          ele.List.forEach(series => {
            item.list.push({
              'id': series.I,
              'name': series.N
            })
          })
          carSeries.push(item);
        })
        return;
      }
    });
    if (callback && typeof callback === 'function') {
      callback(carSeries)
    };
    return;
  },
  getSpecData: function(key, callback) {
    var carSpec = [];
    if (specData && specData.List.length > 0) {
      specData.List.forEach(ele => {
        var item = {
          'id': '',
          'name': '',
          'list': []
        };
        item.id = ele.I;
        item.name = ele.N; 
        ele.List.forEach(spec => {
          item.list.push({
            'id': spec.I,
            'name': spec.N,
            'price': spec.P
          })
        })
        carSpec.push(item)
      })
      if (callback && typeof callback === 'function') {
        callback(carSpec);
      };
      return;
    }
  }
}
$('#js-select-brand').carpicker({
  selectLevel: 'series',
  onInitPicker: dataCar.getBrandData,
  onBrandPicker: function (id) {
    dataCar.getSeriesData(id, function (data) {
      // 全部车系项
      var seriesItem = {
        'show': true,
        'link': true,
        'url': '//www.autohome.com.cn/'
      }
      $('#js-select-brand').data('fe.carpicker').setSeries(data, seriesItem);
    })
  },
  onSeriesPicker: function (id) {
    dataCar.getSpecData(id, function (data) {
      $('#js-select-spec').data('fe.carpicker').setSpec(data);
    });
  }
