Javascript ReactJS:setState在状态对象上
我在我的州有:Javascript ReactJS:setState在状态对象上,javascript,reactjs,Javascript,Reactjs,我在我的州有: state = { validationButton: { button1: false } } componentDidMount(){ //.... this.check(1) this.check(2) } check(Number){ let today = new Date() // I call my api to see if exists document with the number db.get(`${Number}:${tod
state = {
validationButton: {
button1: false
}
}
componentDidMount(){
//....
this.check(1)
this.check(2)
}
check(Number){
let today = new Date()
// I call my api to see if exists document with the number
db.get(`${Number}:${today}`)
.then( (doc) => {
//after that I found document:
// * this is what I would to do *
this.setState((this.state.validationButton[`button${Number}`] = true))
})
}
但我收到了错误消息:
不变冲突:setState(…):获取要更新的状态变量对象或返回状态变量对象的函数
如何设置为true?
setState
应该设置一个对象:
this.setState({ validationButton: {[`button${Number}`]: true });
setState
应获取要设置的对象:
this.setState({ validationButton: {[`button${Number}`]: true });
我相信你能做到:
this.setState({validationButton:{[`button${Number}`]:true});
我相信你可以做到:
this.setState({validationButton:{[`button${Number}`]:true});
