有谁能告诉我为什么我的验证被忽略了? 这是我的表格:
<form name="contactForm" role="form" ng-submit="controller.submit()" novalidate>
<div class="form-group" ng-class="{ 'has-error' : contactForm.fullName.$invalid && !contactForm.fullName.$pristine }">
<input class="form-control" type="text" name="fullName" placeholder="Full name" ng-model="controller.model.fullName" required />
</div>
<div class="form-group" ng-class="{ 'has-error' : contactForm.email.$invalid && !contactForm.email.$pristine }">
<input class="form-control" type="text" name="email" placeholder="Email address" ng-model="controller.model.email" required />
</div>
<div class="form-group" ng-class="{ 'has-error' : contactForm.phoneNumber.$invalid && !contactForm.phoneNumber.$pristine }">
<input class="form-control" type="text" name="phoneNumber" placeholder="Phone number" ng-model="controller.model.phoneNumber" required />
</div>
<div class="form-group" ng-class="{ 'has-error' : contactForm.orderQuantity.$invalid && !contactForm.orderQuantity.$pristine }">
<select class="form-control" name="orderQuantity" ng-model="controller.model.orderQuantity">
<option disabled selected>Order quantity</option>
<option>10+</option>
<option>20+</option>
<option>30+</option>
<option>40+</option>
</select>
</div>
<div class="form-group" ng-class="{ 'has-error' : contactForm.country.$invalid && !contactForm.country.$pristine }">
<input class="form-control" type="text" name="country" placeholder="Country" ng-model="controller.model.country" required />
</div>
<div class="form-group">
<textarea class="form-control" placeholder="Message" ng-model="controller.model.message"></textarea>
</div>
<div class="form-group">
<div class="recaptcha" theme="dark" vc-recaptcha key="'6Lcc0AgTAAAAAIpcEqqDI3Ko8dZ05H-GGgUnfOvA'"></div>
</div>
<div class="form-group">
<button class="btn btn-primary">Send</button>
</div>
</form>
我在这里设置了一个codepen: http://codepen.io/r3plica/pen/XbzyzQ?editors=101

您应该使用 contactForm。$ submitted 检查表单是否已提交。
表单提交后, formController对象会更新,每个控件模型的各个参数都会更新,然后您可以验证您的数据。
您尚未在表单验证中对此进行检查。 更新的html是
<div class="container" ng-app="validationExample">
<div class="row" ng-controller="ValidationController as controller">
<form style="margin-top: 20px;" name="contactForm" role="form" ng-submit="controller.submit()" novalidate>
<div class="form-group" ng-class="{ 'has-error' : contactForm.fullName.$invalid && contactForm.$submitted }">
<input class="form-control" type="text" name="fullName" placeholder="Full name" ng-model="controller.model.fullName" required />
</div>
<div class="form-group" ng-class="{ 'has-error' : contactForm.email.$invalid && contactForm.$submitted }">
<input class="form-control" type="email" name="email" placeholder="Email address" ng-model="controller.model.email" required />
</div>
<div class="form-group" ng-class="{ 'has-error' : contactForm.phoneNumber.$invalid && contactForm.$submitted }">
<input class="form-control" type="tel" name="phoneNumber" placeholder="Phone number" ng-model="controller.model.phoneNumber" required />
</div>
<div class="form-group" ng-class="{ 'has-error' : contactForm.$submitted && contactForm.orderQuantity.$invalid && contactForm.orderQuantity.$error.required }">
<select class="form-control" required name="orderQuantity" ng-model="controller.model.orderQuantity">
<option disabled selected>Order quantity</option>
<option>10+</option>
<option>20+</option>
<option>30+</option>
<option>40+</option>
</select>
</div>
<div class="form-group" ng-class="{ 'has-error' : contactForm.country.$invalid && contactForm.$submitted}">
<input class="form-control" type="text" name="country" placeholder="Country" ng-model="controller.model.country" required />
</div>
<div class="form-group">
<textarea class="form-control" placeholder="Message" ng-model="controller.model.message"></textarea>
</div>
<div class="form-group">
<button class="btn btn-primary" type="submit">Send</button>
</div>
</form>
</div>
</div>
以下是更新后的代码codepen
您也可以使用必需来验证字段,而不是 $ invalid 。您还可以使用正则表达式来放置自定义验证规则。
e.g。
<input name="first_name" class="form-control" required type="text" ng-model="NewUser.first_name" ng-pattern="/^[A-Za-z]+[0-9]*$/" />
<span ng-show="newuser.first_name.$error.pattern">This is not valid <b>Last name</b></span>

实际上,验证不会被忽略。在codepen
代码中,输入任何文本并删除为空。然后切换到另一个输入元素。添加了has-error
类。
因为您正在检查$dirty
,如果您不更改任何输入文本(https://docs.angularjs.org/api/ng/type/form.FormController),则默认为false
:
$ dirty boolean
如果用户已与表单进行过互动,则为True。
我在您的代码中添加了ng-minlength=5
:http://codepen.io/anon/pen/xGPmqR:
<div class="form-group" ng-class="{ 'has-error' : contactForm.fullName.$invalid && contactForm.fullName.$dirty }">
<input class="form-control" type="text" name="fullName" placeholder="Full name" ng-model="controller.model.fullName" required ng-minlength=5 />
</div>
当您输入任何文字时,ng-minlength
规则正在运作。
