我有一个使用Ng指令进行所需验证的字段，但默认情况下，我想使用我的本地存储密钥localstorage.getItem('actreel');
FIELD
<div class="row">
<div class="col-8">
<input id="batchno" type="text" (ngModel)="model.reelno" name="reelno" #reelno="ngModel" placeholder="Reel No. *" value="" required>
</div>
<div class="col-12 rqderror" [hidden]="reelno.valid || reelno.untouched">
Reel is required
</div>
</div>
您应该在ngOnInit事件的ts控制器中感觉到这种情况：
ngOnInit(){
this.actreel = localstorage.getItem('actreel');
}
然后在您的视图字段中使用它：
<div class="row">
<div class="col-8">
<input id="batchno" type="text" [(ngModel)]="actreel" name="reelno" #reelno="ngModel" placeholder="Reel No. *" value="" required>
</div>
<div class="col-12 rqderror" [hidden]="reelno.valid || reelno.untouched">
Reel is required
</div>
</div>
