遍历数组将对象push()到新数组里面，在vue里面一直出错

Question

需求：遍历数组，用if判断选出符合要求的对象，然后把它push到新的数组里面

上代码：

GetAlbumList() {

        let uid = this.$route.query.Uid

    this.$http.get(url, {params: {

      '': this.userInformation

    }}).then((res) => {

      this.aList = res.data.Data.List

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

        if (this.aList[i].Access != 0) {

          console.log(this.aList[i])

          this.albumNameList.push(this.aList[i])

        }

      }

    })

  }

  

 console.log出来的对象都是正确的，在if里面使用push就报错了，除去if条件，用push就不报错了，但是这样又租不到需求，请问这是什么原因？
