微信小程序 picker 组件,当  range 为 Object Array 类型时

wxml:

<picker bindchange="bindPickerChange" value="{{index}}" range-key="name" range="{{objectArray}}">
    <view class="picker">
      当前选择:{{objectArray[index].name}}
    </view>
</picker>

js:

Page({
  data: {
    objectArray: [
      {
        id: 0,
        name: '美国'
      },
      {
        id: 1,
        name: '中国'
      },
      {
        id: 2,
        name: '巴西'
      },
      {
        id: 3,
        name: '日本'
      }
    ]
  },
  bindPickerChange: function(e) {
    console.log('picker发送选择改变,携带值为', e.detail.value)
    var index = e.detail.value;
    var currentId = this.data.objectArray[index].id; 
    this.setData({
      index: e.detail.value
    })
  }
})
