当我在反应中更新状态时，这是我如何避免更改状态？

Question

I read that I should be using functional setState and also not mutating my state.

Is this how that works?

onChangeTextInput = ({ name, value }) => {
    this.setState(state => ({
      ...state,
      form: {
        ...state.form,
        [name]: value
      }
    }));
  };

Answer 1

this.setState({ form: {...this.state.form, [name]: value }});

The above is the simpler form for what you trying to do. When it says don't mutate directly, what it means is dont do something like this.state.form = newObj
