使用带动态名称的输入进行AngularJS电子邮件验证

Question

我有以下代码，我使用AngularJS验证电子邮件输入。这是一个ng-repeat，我跟踪这个人使用＆data; tulifiateSelect.cusomter_no＆＃39;。

我将customer_no附加到电子邮件输入的名称，以确保它们都具有唯一的名称。 如何在span.error-msg ngShow表达式中引用此名称？我尝试了几种不同的方法但没有成功。

提前致谢。

<form name="registrantForm" ng-submit="submitRegistrantForm()" novalidate>    
<div class="session-registrant-field field-email" ng-if="data.affiliateSelect.ask_email == 'Y'">
   <label for="">Email
      <span class="error-msg" ng-show="registrantForm.$submitted || registrantForm.(email+'-'+data.affiliateSelect.customer_no).$touched">
      <span ng-show="registrantForm.(email+'-'+data.affiliateSelect.customer_no).$error.required">Please provide your email.</span>
      <span ng-show="registrantForm.(email+'-'+data.affiliateSelect.customer_no).$error.email">Please enter a valid email.</span>
      </span>
   </label>
   <input type="email" name="email-{{data.affiliateSelect.customer_no}}" id="email-{{data.affiliateSelect.customer_no}}" value"" ng-model="affiliateEmail" required>          
</div>
</form>

Answer 1

registrantForm['email-' + cartPerf.perf_no + data.affiliateSelect.customer_no].$error.required

以上是我需要使用的正确语法。
