AngularJS Ajax

AngularJS provides the $http control, which can be used as a service to read data from the server. The server performs a database call to get the required records. AngularJS requires data in JSON format. Once the data is prepared, it can be retrieved from the server using $http in the following way-

function studentController($scope,$https:) {
   var url = "data.txt";
   $https:.get(url).success(function(response) {
      $scope.students = response; 
   });
}

Here, the file data.txt contains student records. The $http service sends an AJAX call and sets the response to its students property. The student model can be used to draw an HTML table.

Example

data.txt

[
   {
      "Name": "Sea Gull",
      "RollNo": "" 101,
      "Percentage": ""80%"
   },
   {
      "Name": "Dinkar Kad",
      "RollNo": "" 201,
      "Percentage": ""70%"
   },
   {
      "Name": "Robert",
      "RollNo": "" 191,
      "Percentage": ""75%"
   },
   {
      "Name": "Julian Joe",
      "RollNo": "" 111,
      "Percentage": ""77%"
   }]
