vue新建数组对象动态赋值

三种方式：

           //  [{value:'',lable:''},{value:'',lable:''}...]
                        

           //1
           for (let i = 0; i < response.data.length; i++) {
              this.arr[i] = {
                label: response.data[i].name,
                value: response.data[i].sex
              }
            }


          //2
          response.data.forEach((e) => {
            this.arr.push({ value: e.name, lable: e.sex });
          })


          //3
          for (let index = 0; index < response.data.length; index++) {
              this.arr.push({ value: "",lable:"" });
              this.arr[index].value= response.data[index].name;
              this.arr[index].lable= response.data[index].sex;
          }
