ngval
ASP.NET MVC validation for AngularJS.
Getting Started
1.Add data anotations to your entities
public class TestEntity
{
[Required]
public string RequiredProperty { get; set; }
[StringLength(10)]
public string Length10Property { get; set; }
[Required]
[StringLength(10)]
public string MultipleValidationProperty { get; set; }
}2.Reference ngval.js to your page
<script src="~/Scripts/ngval.js"></script>3.Add ngval module to your app module dependencies
var App = angular.module('App', ['ngval']);4.Use NgValFor Html helper method to insert angularjs directives for validation. It will also add native angularjs directives. And you can use ngval object for error messages and more.
<form name="testForm" novalidate ng-submit="submit()">
<input type="text" name="username" ng-model="user.name" @Html.NgValFor(u => u.RequiredProperty) />
{{testForm.username.ngval.hasError}}
<div ng-repeat="err in testForm.username.ngval.errors">
<span>{{err.message}}</span>
<br />
</div>
<input type="submit" />
</form>
