Phantom js 不支持箭头函数 (=>)

Question

我正在使用 Jasmine 对 Angular 应用程序进行单元测试。在 Chrome 上一切正常，直到我开始使用 PhantomJs 进行无头浏览器测试或在控制台上测试输出。

2天后发现PhantomJs不支持lambda表达式。单元测试没有任何问题，但 lambda 表达式和 PhantomJs 有问题。

我正在使用-

AngularJs - 1.6.6
茉莉花 - 2.9.1
PhantomJs - 2.1.1

谁能帮我解决这个问题？

提前致谢。

Answer 1

PhantomJs doesn't support arrow functions yet. In fact, it supports very little of ES2015. See this comment from pixiuPL (the maintainer) from this issue 在他们的仓库中：

Introducing ECMA will require nearly-complete rewrite and - keeping in m8ind I seem to be the only active dev of PJS now - will need to wait till other - more urgent - issues are solved.

In the meantime, if you feel skilled enough - feel free to start working on it, but on the separate branch.

Answer 2

改用函数表达式。如果要捕获 this 值，请添加 bind。

例如

变化：

(foo, bar) => this.example(bar, foo);

到

(function (foo, bar) { return this.example(bar, foo); }).bind(this)
