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

 
  当前选择：{{objectMultiArray[0][multiIndex2[0]].name}}，{{objectMultiArray[1][multiIndex2[1]].name}}
 

Page({

 /**
 * 页面的初始数据
 */
 data: {
 objectMultiArray: [
  [
  {
   id: 0,
   name: &＃39;无脊柱动物&＃39;
  },
  {
   id: 1,
   name: &＃39;脊柱动物&＃39;
  }
  ], [
  {
   id: 0,
   name: &＃39;扁性动物&＃39;
  },
  {
   id: 1,
   name: &＃39;线形动物&＃39;

  {
   id: 3,
   name: &＃39;节肢动物&＃39;
  }
  ]
 ],
 multiIndex2: [0, 0],
 },


 bindMultiPickerChange2: function (e) {
 console.log(&＃39;picker发送选择改变，携带值为&＃39;, e.detail.value)
 this.setData({
  multiIndex2: e.detail.value
 })
 },
 bindMultiPickerColumnChange2: function (e) {
 console.log(&＃39;修改的列为&＃39;, e.detail.column, &＃39;，值为&＃39;, 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: &＃39;扁性动物&＃39; },
    { id: 1, name: &＃39;线形动物&＃39; },
    { id: 2, name: &＃39;环节动物&＃39; },
    { id: 3, name: &＃39;软体动物&＃39; },
    { id: 3, name: &＃39;节肢动物&＃39; }
   ];
   // data.multiArray[2] = [&＃39;猪肉绦虫&＃39;, &＃39;吸血虫&＃39;];
   break;
   case 1:
   data.objectMultiArray[1] = [
    { id: 0, name: &＃39;鱼&＃39; },
    { id: 1, name: &＃39;线形两栖动物&＃39; },
    { id: 2, name: &＃39;爬行动物&＃39; }
   ];
   break;
  }
  data.multiIndex2[1] = 0;
  // data.multiIndex[2] = 0;
  break;
 }
 this.setData(data);
