Angular JS和ASP服务器端控制验证

Question

I am using angular JS for asp.net server side controls

<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>

problem is at run time when i deploy my code , name property changes for server side control so i am not able to render paragraph of error messages is there any other way through which i can access control instead of myform.txtName.$invalid??

tried with clientIDmode= Static , it keeps id static but name still changes,

Try this solution jsfiddle .

Create a directive alias , which stores a reference to ngModelController , which is independent of the name of input (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>
