为什么选择multiSelector中的内容后报错？ - WXOPEN Club

Page({

data: {

multiSelectorItems:[["罗宋汤","鸡蛋汤"],["牛排","猪排","鱼排"],["冰激凌","鸡蛋布丁"]]

},

multiSelectorChange:function(e)

{

let arrayIndex = e.detail.value;

let array = this.data.multiSelectorItems;

let value = new array();

for(let i=0;i<arrayIndex.length;i++){

let k = arrayIndex[i];

let v = array[i][k];

value.push(v);

this.Setdata({multiSelector:value});

}

},）

<picker mode="multiSelector" range="{{multiSelectorItems}}" bindchange="multiSelectorChange">

<view style="border: 2px solid black;">你选择的是：{{multiSelector}}</view>

</picker>

请问一下各位大佬，这是怎么一回事？每次点击确定后没有数据显示，控制台报错。各位大佬怎么解决啊~~~~~~
