答案 0 :(得分：1)
您可以通过投掷typeof条件块轻松解决错误。
我猜测你的代码中的某个地方，当它实际需要2时，你只会将1个参数传递给getScript。
我整理了一个缩小的JSFiddle来说明问题。
要带走的关键事项是typeof：
if (typeof (success) === "function") {
success();
}
传递给getScript函数的参数数量。
getScript("https://ajax.googleapis.com/ajax/libs/angular_material/1.0.0/angular-material.min.js", test);
如果您想重新创建错误，只需从test函数调用中删除getScript，然后删除typeof项检查。
