 class ServiceRecordGridFields{
  constructor(){
    this.allColumns = [
    {
      field:'assemblynumber',
      name:'Assembly',
      visible:false,
      width:175
    },{
      field:'assetid',
      name:'Asset ID',
      visible:false,
      width:110
    }];
  }
  getAllColumns(){

    return this.allColumns;
  }
}
export default ServiceRecordGridFields;

我在其他地方

import ServiceRecordGridFields from './_serviceRecordGridFields.js';


class serviceRecordGridsCtrl{

  constructor(){

this._ServiceRecordGridFields = ServiceRecordGridFields;

this._serviceRecordsResolve = serviceRecordsResolve;


  } 

  bclick(){
console.log(this._ServiceRecordGridFields.getAllColumns());
  }
  }

调用得到的函数“ this._ServiceRecordGridFields.getAllColumns不是函数”。

如果我在getAllColumns（）前面添加“ static”，则返回undefined。我究竟做错了什么？
