通过创建新的空白项目将我的项目更新到最后的Ionic版本（3.3.0）后，我遇到了一些破坏了我的逻辑的奇怪问题。一些正则表达式但不是全部都被打破了。
例如，标记该字段required已不再有效。
<ion-item>
<ion-input type="email" placeholder="Email" required [(ngModel)]="email" name="email"></ion-input>
<ion-icon name="person" item-left no-padding></ion-icon>
</ion-item>
始终返回true。
这很好用：
<ion-item>
<ion-label floating>First Name*</ion-label>
<ion-input type="text" required [(ngModel)]="regModel.FirstName" name="FirstName"
#FirstName="ngModel"
pattern="[a-zA-Z ]*"></ion-input>
</ion-item>
这些不是：
<ion-item>
<ion-label floating>Zip Code(5 digits)</ion-label>
<ion-input type="number" [(ngModel)]="regModel.Addresses[0].Zip" #Zip="ngModel" name="Zip"
pattern="\d{5}"></ion-input>
<ion-spinner icon="crescent" *ngIf="showProgress" item-right no-padding></ion-spinner>
</ion-item>
<ion-item no-border no-lines no-margin *ngIf="!(Zip.valid) && Zip.dirty" color="danger">
<small> Zip code required in 5 digits format</small>
</ion-item>
<ion-item>
<ion-label floating>Password*</ion-label>
<ion-input type="password" required [(ngModel)]="regModel.Password" name="Password"
#Password="ngModel" pattern="^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)[a-zA-Z\d*\w]{5,}$"
(change)="checkPassword()"></ion-input>
</ion-item>
<ion-item no-border no-lines no-margin *ngIf="!Password.valid && Password.dirty" color="danger">
<small>Five characters minimum,</small>
<br>
<small> at least 1 uppercase, 1 lowercase and 1 number
</small>
</ion-item>
总是返回假。
这是已知的问题吗？
