我的状态:
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))
})
}
但我收到错误消息:
<块引用>Invariant Violation:setState(...):需要一个状态变量对象来更新或一个函数返回一个状态变量对象。
如何设置为true?

setState
应该得到一个要设置的对象:
this.setState({ validationButton: {[`button${Number}`]: true });

我相信你能做到:
this.setState({ validationButton: {[`button${Number}`]: true });
