Cannot read property 'push' of null vue2.0

Question

let data = {

      orderNum:this.orderNum,
      receiverName:this.consigneeName,
     };
     
    if(!this.consigneeVisible2){//添加
       this.receiverInfo.push(data);
    }
    

this.receiverInfo是我在data里定义的一个数组，一添加就会报这个错

看一下this.receiverInfo的初始定义

Answer 2

是怎么定义的呢？

Answer 3

你把代码贴全吧，有些初始声明你还上我们猜

Answer 4
