能實現(xiàn)效果，但感覺太麻煩了。
有沒有簡潔高效的方法？
Template:

<label><input icheck type="checkbox" (click)="onCheckAgree()">同意</label>

<button [disabled]="agreectrl">支付</button>

Ts:

public agree = true;
public agreectrl =true;

onCheckAgree(){
 if(this.agee){
  this.agreectrl = false;
console.log('同意')
this.agree = !this.agree;
} else {
  this.agreectrl = true;
console.log('取消了協(xié)議')
this.agree = !this.agree;
}
}
