AngularJS提供$http控制，可以作为一项服务从服务器读取数据。服务器可以使一个数据库调用来获取记录。 AngularJS需要JSON格式的数据。一旦数据准备好，$http可以用以下面的方式从服务器得到数据。
function studentController($scope,$http) {
var url="data.txt";
$http.get(url).success( function(response) {
$scope.students = response;
});
} |
例子
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%"
}
]

要要运行这个例子，需要部署textAngularJS.html，data.txt到一个网络服务器。使用URL在Web浏览器中打开textAngularJS.html请求服务器。看到结果如下：
