Can we create a popup alert that says "Error Contacting Server" when the http request does not receive any response?
.controller('items_ctrl',['$scope','$http',function($scope,$http){
$scope.shop_id=localStorage.getItem("shop_id");
$http.get('http://localhost/myapp/spree/stocks.php').success(function(data){
console.log(JSON.stringify(data));
$scope.item=data;
});
}])
It's recommended to utilize the then function instead of using the success/error methods
Below is the revised version of your code snippet:
.controller('items_ctrl',['$scope','$http',function($scope,$http){
$scope.shop_id=localStorage.getItem("shop_id");
$http.get('http://localhost/myapp/spree/stocks.php').then(function(data){
console.log(JSON.stringify(data));
$scope.item=data;
}, function(error){
alert("Error contacting server");
});
}])
It is important to define an error callback function when making a request.
$http.get('/someOtherUrl', config).then(handleSuccess, handleFailure);

Implement a promise and set a timeout in your JavaScript code.
var cancelRequest = $q.defer();
$http.get('/someUrl', {timeout: cancelRequest.promise}).success(successCallback);
$timeout(showErrorPopup, 3000);
Once the timeout is reached, resolve the promise and then display the popup.
function showErrorPopup(){
cancelRequest.resolve();
//popup code
