[英]show an alert when http requesht has lasted for x seconds without response with angularjs
[英]popup alert when http request last x seconds with angularjs
當HTTP請求未獲得任何反饋時,我想彈出並警告說“ Error Contacting Server”。
.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));
$scope.item=data;
});
}])
您應該使用then
而不是success/error
方法
這是您更新的代碼
.controller('items_ctrl',['$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");
});
}])
您應該指定錯誤回調函數。
$http.get('/someUrl', config).then(successCallback, errorCallback);
有關更多信息,請參見https://docs.angularjs.org/api/ng/service/ $ http
為此使用諾言。請在JavaScript中設置一些超時時間。
var cancelReq= $q.defer();
$http.get('/someUrl', {timeout: cancelReq.promise}).success(successCallback);
$timeout(showErrorPopup, 3000);
超時后,解決它,然后顯示彈出窗口
function showErrorPopup(){
cancelReq.resolve();
//popup code
}
