在角度2中,我想在用户离开现场区域后才进行客户端验证。这是因为当用户输入电子邮件或电话等字段时,他们总是会在完成输入完整的电子邮件之前收到错误,这不是最佳的用户体验。
目前我使用过
address1: ['', Validators.compose([Validators.required,
Validators.maxLength(128), Validators.minLength(5)])],
模板:
<div class="addres">
<label class="form_label asterisk">Address Line 1</label>
<textarea class="form_input " formControlName="address1"></textarea>
<div class="error" *ngIf="addDealerForm.controls['address1'].errors && (addDealerForm.controls['address1'].touched)">
<div *ngIf="addDealerForm.controls['address1'].hasError('required')">
Address1 is required.
</div>
<div *ngIf="addDealerForm.controls['address1'].hasError('maxlength')">
Exceeded maximum character length.
</div>
<div *ngIf="addDealerForm.controls['address1'].hasError('minlength')">
Enter minimum character length.
</div>
</div>
</div>
帮助我解决此问题。

我认为你需要在(blur)
方法上设置验证。对于前
//组件
onBlur() {
this.formControl.get(name).setValidators('', [Validators.minLength(3));
}
//表格
<textarea class="form_input " formControlName="address1" (blur)="onBlur()"></textarea>
