AngularJs ng-repeat Example

Angular js URL:

<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>  

Html tag:

<div ng-app="myApp" ng-controller="myCntrl">
<table>
<thead>
<tr>
<th>
Emp Code.
</th>
<th>
Employee Name
</th>
<th>
Pan No
</th>
</tr>
</thead>
<tr ng-repeat="student in EmployeeList">
<td ng-bind="student.StudentID">
</td>
<td ng-bind="student.StudentName">
</td>
<td ng-bind="student.PanNO">
</td>
</tr>
</table>
</div>

Angular js Script :

<script>
var app = angular.module("myApp", []);
app.controller("myCntrl", function ($scope, $http) {
$scope.fillList = function () {
$scope.EmployeeName = "";
var httpreq = {
method: 'POST',
url: 'Default2.aspx/GetList',
headers: {
'Content-Type': 'application/json; charset=utf-8',
'dataType': 'json'
},
data: {}
}
$http(httpreq).success(function (response) {
$scope.EmployeeList = response.d;
})
};
$scope.fillList();
});
</script>

Asp.net Cs page code:
