微信小程序中range-key多列选择器的使用示例

本文实例为大家分享了微信小程序多列选择器的具体代码，供大家参考，具体内容如下

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

Page({   /**    * 页面的初始数据    */   data: {    objectMultiArray: [     [      {       id: 0,       name: '无脊柱动物'      },      {       id: 1,       name: '脊柱动物'      }     ], [      {       id: 0,       name: '扁性动物'      },      {       id: 1,       name: '线形动物'      },      {       id: 2,       name: '环节动物'      },      {       id: 3,       name: '软体动物'      },      {       id: 3,       name: '节肢动物'      }     ]    ],    multiIndex2: [0, 0],   },       bindMultiPickerChange2: function (e) {    console.log('picker发送选择改变，携带值为', e.detail.value)    this.setData({     multiIndex2: e.detail.value    })   },   bindMultiPickerColumnChange2: function (e) {    console.log('修改的列为', e.detail.column, '，值为', 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: '扁性动物' },         { id: 1, name: '线形动物' },         { id: 2, name: '环节动物' },         { id: 3, name: '软体动物' },         { id: 3, name: '节肢动物' }        ];        // data.multiArray[2] = ['猪肉绦虫', '吸血虫'];        break;       case 1:        data.objectMultiArray[1] = [         { id: 0, name: '鱼' },         { id: 1, name: '线形两栖动物' },         { id: 2, name: '爬行动物' }        ];        break;      }      data.multiIndex2[1] = 0;      // data.multiIndex[2] = 0;      break;    }    this.setData(data);   }      })
