本文實例為大家分享了微信小程序多列選擇器的具體代碼，供大家參考，具體內容如下

<picker mode="multiSelector" bindchange="bindMultiPickerChange2" bindcolumnchange="bindMultiPickerColumnChange2" value="{{multiIndex}}" range="{{objectMultiArray}}" range-key="{{'name'}}">
  <view class="picker">
   當前選擇：{{objectMultiArray[0][multiIndex2[0]].name}}，{{objectMultiArray[1][multiIndex2[1]].name}}
  </view>
</picker>

Page({
 /**
  * 頁面的初始數據
  */
 data: {
  objectMultiArray: [
   [
    {
     id: 0,
     name: '無脊柱動物'
    },
    {
     id: 1,
     name: '脊柱動物'
    }
   ], [
    {
     id: 0,
     name: '扁性動物'
    },
    {
     id: 1,
     name: '線形動物'
    },
    {
     id: 2,
     name: '環節動物'
    },
    {
     id: 3,
     name: '軟體動物'
    },
    {
     id: 3,
     name: '節肢動物'
    }
   ]
  ],
  multiIndex2: [0, 0],
 },


 bindMultiPickerChange2: function (e) {
  console.log('picker發送選擇改變，攜帶值為', e.detail.value)
  this.setData({
   multiIndex2: e.detail.value
  })
 },
 bindMultiPickerColumnChange2: function (e) {
  console.log('修改的列為', e.detail.column, '，值為', e.detail.value);
  var data = {
   objectMultiArray: this.data.objectMultiArray,
   multiIndex2: this.data.multiIndex2
  };
  data.multiIndex2[e.detail.column] = e.detail.value;
  switch (e.detail.column) {
   case 0:
    switch (data.multiIndex2[0]) {
     case 0:
      data.objectMultiArray[1] = [
       { id: 0, name: '扁性動物' },
       { id: 1, name: '線形動物' },
       { id: 2, name: '環節動物' },
       { id: 3, name: '軟體動物' },
       { id: 3, name: '節肢動物' }
      ];
      // data.multiArray[2] = ['豬肉絳蟲', '吸血蟲'];
      break;
     case 1:
      data.objectMultiArray[1] = [
       { id: 0, name: '魚' },
       { id: 1, name: '線形兩棲動物' },
       { id: 2, name: '爬行動物' }
      ];
      break;
    }
    data.multiIndex2[1] = 0;
    // data.multiIndex[2] = 0;
    break;
  }
  this.setData(data);
 }


})
