Question

我正在使用angular JS for asp.net服务器端控件

<div class="gridpage mb40" name="myForm" ng-model="myForm" ng-form
   <div class="form-group">
      <label class="">Name of the Supplier:</label>
        <asp:TextBox ID="txtSupName" CssClass="form-control" runat="server" ng-model="txtSupName" name="txtName" required></asp:TextBox>
        <p ng-show="myForm.txtName.$invalid && !myForm.txtName.$pristine" class="help-block">Your Name is Required.</p>
   </div>
 </div>

问题是在运行时我部署我的代码，为服务器端控件命名属性更改，所以我无法呈现错误消息的段落有没有其他方法可以访问控件而不是myform.txtName。$ invalid ??

尝试使用clientIDmode= Static，它会保持id静态，但名称仍会更改，

尝试此解决方案jsfiddle。

创建一个指令alias，它存储对ngModelController的引用，该引用独立于输入的name（asp：TextBox）。

var myApp = angular.module('myApp', []);

myApp.controller('MyCtrl', function($scope, $log) {

  })
  .directive('alias', function() {
    return {
      restrict: "A",
      require: "ngModel",
      scope: {
        alias: "="
      },
      link: function(scope, elem, attr, ngModel) {
        scope.alias = ngModel;
      }
    }
  });

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp">
  <div ng-controller="MyCtrl">
    <form name="myForm">
      <input name="txtName" ng-model="txtName" required alias="aliasName" ng-pattern="/^[0-9]+$/">
      <div ng-if="myForm.txtName.$error.required">Name is reauired by name</div>
      <div ng-if="aliasName.$error.required">Name is reauired by alias</div>
      <div ng-if="myForm.txtName.$error.pattern">Invalid pattern by name</div>
      <div ng-if="aliasName.$error.pattern">Invalid pattern by alias</div>
      <br>
      <pre>myForm.txtName.$error = {{myForm.txtName.$error|json}}</pre>
      <pre>aliasName.$error = {{aliasName.$error|json}}</pre>
    </form>
  </div>
</div>
