angularjs – 设置$invalid和$error不会使表单无效

我有一个表单,我正在将我的电话字段从使用正则表达式更改为intl-tel输入模块.我遇到问题在检查有效#s时混淆.

我有一个表单与这些领域的几个…

<div class="row">
<div class="col-xs-2">
    <label for="cellPhone"
           translate>CONTACT.CELL</label>
</div>
<div class="col-xs-6"
     ng-class="{'has-error': !cellPhoneFocus && forms.contactForm.cellPhone.$invalid && forms.contactForm.cellPhone.$touched }">
    <input type="text" class="form-control intlPhoneInput"
           id="cellPhone" name="cellPhone"
           ng-model="contact.cellPhone.display"
           ng-focus="cellPhoneFocus = true"
           ng-blur="cellPhoneFocus = false; validatePhone($event)">
    <div ng-messages="forms.contactForm.cellPhone.$error"
         ng-show="!cellPhoneFocus && forms.contactForm.cellPhone.$touched"
         class="errormessages">
        <p ng-message="pattern" translate>
            CRUD.VALID_PHONE</p>
    </div>
</div>

并提交…

<button type="submit" class="btn btn-priMary" ng-disabled="forms.contactForm.$invalid" id="saveContactLink" translate>CRUD.SAVE</button>

然后在我的控制器(Typescript)…

//In Constructor
$scope.validatePhone = this.validatePhone.bind(this);

//Outside constructor
private validatePhone(eventObject: any) {
    let thePhoneField = $('#' + eventObject.target.id);
    let phoneIsValid = thePhoneField.intlTelInput("isValidnumber");

    this.$scope.forms.contactForm[eventObject.target.id].$invalid = !phoneIsValid;
    this.$scope.forms.contactForm[eventObject.target.id].$error = {"pattern": !phoneIsValiD};
}

这样可以正确设置我的错误类和错误消息,但不会将FORM设置为无效.我试过$SETVALidity …

this.$scope.forms.contactForm[eventObject.target.id].$SETVALidity('pattern',!phoneIsValid);

…但似乎根本不做任何事情.

如何将该字段设置为无效,显示正确的ng消息(如果有多个),并确保窗体$errors更新,以便提交被禁用？
