Javascript 如果有角度，则管理错误ng

我有一个带有选择选项的表单。如果值为“是”，则显示一个div。当我验证表单时，不会显示

<div class="row">
    <div class="col-md-6">
       <div class="form-group" ng-class="{ 'has-error': invalid.backendIntegrationUrl, 'has-success': valid.backendIntegrationUrl}">
          <label for="backendIntegrationUrl">backend service URL *</label>
          <input type="text" name="backendIntegrationUrl" class="form-control" placeholder="example: https://qualif.myapi.com/myapi/v1 " ng-model="api.backendIntegrationUrl"  ng-required="true">
          <span id="helpBlock" class="help-block" ng-show="help.backendIntegrationUrl.required">backend service URL is required.</span>            
       </div>
     </div>
     <div class="col-md-6">
        <div class="form-group" id="basicAuth">
          <label for="basicAuth">basic auth info</label>
          <select name="basicAuth" class="form-control" ng-init="api.basicAuth = api.basicAuth || 'no'" ng-model="api.basicAuth" id="basicAuth" >
              <option value="no">no</option>
              <option value="yes">yes</option>
          </select>
        </div>                               
     </div>
</div>

<div class="row" ng-if="api.basicAuth == 'yes'" id="yesAuth">
        <div class="col-md-6" ng-class="{ 'has-error': invalid.basicAuthForBackendUsername, 'has-success': valid.basicAuthForBackendUsername}">
           <div class="form-group" >
               <label for="basicAuthForBackendUsername">basic auth username *</label>
               <input type="text" id="basicAuthForBackendUsername" name="basicAuthForBackendUsername" class="form-control" placeholder="basic auth username" ng-model="api.basicAuthForBackendUsername" ng-required="api.basicAuth =='yes'"> 
               <span id="helpBlock" class="help-block" ng-show="help.basicAuthForBackendUsername.required">basic auth username is required.</span>       
           </div>                                
        </div>
        <div class="col-md-6" ng-class="{ 'has-error': invalid.basicAuthForBackendPassword, 'has-success': valid.basicAuthForBackendPassword}">
           <div class="form-group" >
               <label for="basicAuthForBackendPassword">basic auth password *</label>
               <input type="text" id="basicAuthForBackendPassword" name="basicAuthForBackendPassword" class="form-control" placeholder="basic auth password" ng-model="api.basicAuthForBackendPassword" ng-required="api.basicAuth =='yes'"> 
               <span id="helpBlock" class="help-block" ng-show="help.basicAuthForBackendPassword.required">basic auth password is required.</span>       
           </div>                                
        </div>
 </div>

有效的也一样

我怎样才能解决我的问题，使它也显得毫无价值

非常感谢

请检查

api。basicAuth1

是否未定义

您应该在控制器上全局声明

api.basicAuth

示例如下所示：

function controllername($scope)
{
 $scope.api = { basicAuth: "Yes" }
     .
     .
     .
     .
     // other codes
     .
     .
     .
     .
}

function controllername($scope)
{
 $scope.api = { basicAuth: "Yes" }
     .
     .
     .
     .
     // other codes
     .
     .
     .
     .
}
