如何在 setState 回调中获取更新的状态？

Question

I have a code scenario where I need get the updated state in the setState callback. Like below :

this.setState({name : "xyz"}, () => {
  //I want the updated state here where I need to get the this.state.name should be "xyz"
})

Answer 1

To get the updated state after setting a state is same as described in question.

this.setState({name : "xyz"}, () => {
  console.log(this.state.name)
});

I asked this question as I had some issues in my function and was unable to get the updated state.

Answer 2

Use componentDidUpdate() to get updated state and props values.

    componentDidUpdate(prevProps, prevState) {
      console.log(this.state, prevState);
    }
