android - React Native中的this，怎么理解？

Answer 1

So strange, why do you write it like this? I feel like you can just use this.updateNum(); and this.updatePW(); to get it done, right?

Answer 2

The person above is right. There is a problem with your writing method. There is no need for bind in the constructor. RN generally needs bind when calling methods in a class in render, which means changing the scope so that its methods act on the current operation object
