render(){
var disabled=false;
!this.state.beginTime?(disabled=true):(disabled=false)
return <button disabled={disabled}></button>
}
according to the change of beginTime, set the diasbled property dynamically
this code works well in chrome and Firefox, but it doesn"t work and doesn"t report an error in Safari. The version of Safari is 11.1.2.
doesn't work? Does it have a value of false, or a value of true but no disabled effect?
in addition, your code is not very good, you can write it like this:
render(){
<button disabled={!this.state.beginTime}></button>
}render?
the problem has been solved.
there is no problem with this way of writing, but the time format processed by new Date is not compatible in safari, so the relevant value is always undefined, so the disabled attribute does not take effect.
