Angular反應形式驗證器中的密碼驗證錯誤

Question

使用Angular Reactive Form驗證密碼，以使密碼與atleast匹配：

|*> 1 lowercase
|*> 1 uppercase
|*> 1 numeric
|*> 8 char longer

使用Reg Exp：

"^(?=.*[a-z])(?=.*[A-Z])(?=.*[0-9])(?=.{8,})"

HTML代碼：

<form [formGroup]="NamFomNgs">

    <label>Email : 
        <input type="email" name="MylHtm" formControlName="MylNgs">
    </label><br>
        <div class="ErrMsgCls" *ngIf="(NamFomNgs.controls['MylNgs'].touched || NamFomNgs.controls['MylNgs'].dirty) && 
            !NamFomNgs.controls['MylNgs'].valid">
            <span *ngIf="NamFomNgs.controls['MylNgs'].errors.required">This field is required</span>
            <span *ngIf="NamFomNgs.controls['MylNgs'].errors.email">Enter valid email</span>
        </div><br>

    <label>Password : 
        <input type="text" name="PwdHtm" formControlName="PwdNgs">
    </label><br>
        <div class="ErrMsgCls" *ngIf="(NamFomNgs.controls['PwdNgs'].touched || NamFomNgs.controls['PwdNgs'].dirty) && 
            !NamFomNgs.controls['PwdNgs'].valid">
            <span *ngIf="NamFomNgs.controls['PwdNgs'].errors.required">This field is required</span>
            <span *ngIf="NamFomNgs.controls['PwdNgs'].errors.pattern">Enter valid password</span>
        </div><br>

    <button [disabled]="!NamFomNgs.valid">Submit</button>
</form>

TypeScript代碼：

NamFomNgs:FormGroup;

constructor(private NavPkjVaj: ActivatedRoute, private HtpCncMgrVaj: HttpClient,private FomNgsPkjVaj: FormBuilder){

    this.NamFomNgs = FomNgsPkjVaj.group(
        {
            MylNgs:[null,Validators.compose([
                Validators.required,
                Validators.email ])],
            PwdNgs:[null,Validators.compose([
                Validators.required,
                Validators.pattern("^(?=.*[a-z])(?=.*[A-Z])(?=.*[0-9])(?=.{8,})")])]
        });
}

相同的reg exp顯示對要求有效。 但是它在Angular中無效。 請以正確的方式幫助我並解決此問題。

您只需要在正則表達式組中捕獲正則表達式中的內容即可。 只需像這樣更改長度部分：

"^(?=.*[az])(?=.*[AZ])(?=.*[0-9]).{8,}"
