AngularJS provides $http control which works as a service to read data from the server. The server makes a database call to get the desired records. AngularJS needs data in JSON format. Once the data is ready, $http can be used to get the data from server in the following manner −
function studentController($scope,$https:) { var url = "data.txt"; $https:.get(url).success( function(response) { $scope.students = response; }); }
Here, the file data.txt contains student records. $http service makes an ajax call and sets response to its property students. students model can be used to draw tables in HTML.
Examples
data.txt
[ { "Name" : "Mahesh Parashar", "RollNo" : 101, "Percentage" : "80%" }, { "Name" : "Dinkar Kad", "RollNo" : 201, "Percentage" : "70%" }, { "Name" : "Robert", "RollNo" : 191, "Percentage" : "75%" }, { "Name" : "Julian Joe", "RollNo" : 111, "Percentage" : "77%" } ]
