角度无法分配给“名称”，因为它是常量或只读属性

Question

Im getting error Cannot assign to 'name' because it is a constant or a read-only property. When send data to api. Any one know how can i solve this ? Thanks

  onSubmit() {
  name = this.backUrl || 'admin';
  console.log(name);
    const formData = new FormData();

    formData.append('avatar', this.form.get('avatar').value);
    formData.append('name', name);


    this.uploadService.uploadFile(formData).subscribe(
      (res) => {
        this.uploadResponse = res;
          console.log(res);
      },
      (err) => {  
        console.log(err);
      }
    );
  }

您需要将name声明为let或var才能为其分配值。
