将本机设置状态反应为 true 一秒钟

Question

I have a state:

state = {
showView: false,
}

How can I make a function that when called it changes the showView state to true for 1 second then change it back to false?

Answer 1

this.setState({
  showView: true,
}, () => setTimeout(() => {
  this.setState({
    showView: false,
  })
}, 1000))

This will set the state back to false after briefly (1 second) set it to true, using the React setState callback function.
