Ajax成功vs然后（角度承诺）

Question

我打算在我的应用程序中使用angularjs promise。但是我没有得到.success函数和.then函数之间的实际区别。

Answer 1

1. advantages of promises is the ability to flatten and chain potentially complex sequences of ajax calls. Not only does this help us simplify code, but more importantly, it helps us manage timing and dependencies through a sequence of calls.

2. The fundamental difference between 'success' and 'then' is that success will return the original promise instead of returning a new derived promise. Each then() invocation returns a fresh promise – which is key to chaining multiple promise calls.
