React受控组件的性能问题

Question

I have been using react's controlled components in my application and .

But I am noticing that as I enter more and more inputs to these form components my page is slowing down badly or even hangs sometime.

Any clue ?

Sounds like you should look into the key="" attribute. Most often when react starts to slow down it is related to it doing more work than necessary. Another way to improve performance is implementing shouldComponentUpdate , but that should first be necessary later on.
