与EcmaScript有关的问题：

const firstArg = 'myArg';
this._myFunction(firstArg)
  .then((asyncResponse) => this._secondMethod(asyncResponse))
  .then((asyncSecondResponse, asyncResponse) =>
   this._thirdMethod(asyncSecondResponse, asyncResponse))
  .then(() => this._lastMethod());

问题是：
如何传递给_thirdMethod 2个参数（this._secondMethod(asyncResponse))中的一个-提供一个参数，第二个只是先前的asyncResponse）-我不想在_secondMethod（asyncResponse）中定义它以返回这两个参数参数，只想在我上面编写的此PIPE中执行

有什么语法吗？

最佳答案

您还可以嵌套第二个“ then”以将第一个asyncResponse保留在范围内

this._myFunction(firstArg)
    .then((asyncResponse) => this._secondMethod(asyncResponse)
    .then((asyncSecondResponse) => this._thirdMethod(asyncSecondResponse, asyncResponse)))
    .then(() => this._lastMethod());
  }
