javascript - ng-form模板中的 Angular 丢失范围

Question

我正在尝试，

    <div ng-form="sadadPaymentForm" class="sadadPaymentForm"  ng-if="vm.isSadadEnabled" name="sadadPaymentForm"  validate-popup-form>
     <div ng-if="vm.isSadadEnabled">
       <div class="credit-debit-card-div" ng-include="'sadadTemplate'" ng-show="vm.view_tab == 'tab7'">
       </div>
    </div>
   </div>
   <span ng-show="vm.view_tab=='tab7' && vm.isSadadEnabled">
     <button type="button" class="primary inline pay-now" id="paynowbtn" ng-disabled="!vm.checked3 || vm.sadadPaymentForm.$invalid" ng-click="vm.payByVoucher();" analytics-on="click" analytics-event="uaevent" analytics-eventcategory="Payment" analytics-eventaction="PayNow"
             analytics-eventlabel="Pay now">
               Pay by sadad
     </button>
   </span>

然后，我的模板在另一个 html 文件中

  <script type="text/ng-template" id="sadadTemplate">
    <input fieldlabel="Online Payment ID" type="text" name="onlinePaymentId" ng-model="vm.sadadpayment.onlinePaymentId"  class="form-control input-type-text"
                    ng-model-options="{ debounce: 100 }" validationKey-required="PaymentAdress1IsRequired" required maxlength="200">
  </script>

此处 vm.sadadPaymentForm.$invalid 不起作用，但 Indidual components validation works on blur on blur of input

但是，如果我将 vm 添加到 ng-form 中，即像这样

    <div ng-form="vm.sadadPaymentForm" class="sadadPaymentForm"  ng-if="vm.isSadadEnabled" name="vm.sadadPaymentForm"  validate-popup-form>
     <div ng-if="vm.isSadadEnabled">
       <div class="credit-debit-card-div" ng-include="'sadadTemplate'" ng-show="vm.view_tab == 'tab7'">
       </div>
    </div>
   </div>

此处 vm.sadadPaymentForm.$invalid 有效，但个别组件验证因输入模糊而失败，例如，TypeError: Cannot read property 'onlinePaymentId' of undefined/p>

帮助我了解如何使单独验证和最终表单验证一起工作。Angular Ver 1.5，现在无法升级。需要 1.5 的解决方案。

Answer 1

Form name 属性应该有 sadadPaymentForm 而不是 vm.sadadPaymentForm。由于您没有正确指定表单 name，因此验证失败。

name="vm.sadadPaymentForm" 

应该是

name="sadadPaymentForm"
