callback in $http({method: 'GET', url: $scope.url}) - http

$scope.fetchQA = function() {
$scope.url = 'js/jsons/QA.json';
$http({method: 'GET', url: $scope.url}).
success(function(data, status, headers, config) {
$scope.QA = data;
});
}
$scope.fetchQA();
function x(){
alert(QA);
}
How do i use function x as a callback for $http.get? or is there any other way to ensure that x() will get executed only after reception of data in fetchQA?

Put it in the callback right after your logic:
$http({method: 'GET', url: $scope.url}).
success(function(data, status, headers, config) {
$scope.QA = data;
x();
});

formdata in ajax call

When I pass formdata in ajax call after json return it does not return on Success or error block just printing value on browser
// And my Controller side code is
[HttpPost]
public JsonResult Create(InquiryModel model)
{
var inquiry = _inquiryService.GetInquiryById(model.Id);
return Json(inquiry.Id, JsonRequestBehavior.AllowGet);
}
// View side
var formData = new FormData();
jQuery.each(jQuery('#QuotationDocument')[0].files, function (i, file) {
formData.append('file-' + i, file);
});
$.ajax({
url: '#Url.Action("Create", "Inquiry")',
data: formData,
contentType: false,
processData: false,
type: "POST",
success: function (data) {
alert("ssss");
},
error: function (msg) {
alert("error", msg.statusText + ". Press F12 for details");
}
});
when I pass only formData it works fine
Try like this;
$.ajax({
url: '#Url.Action("Create", "Inquiry")',
data: formData,
datatype: "json",
type: "POST",
success: function (data) {
alert("ssss");
},
error: function (msg) {
alert("error", msg.statusText + ". Press F12 for details");
}
});

using $http with AngularJS

I have the following
angular.module('myApp').factory('dashboard', ['$http', function ($http) {
return {
name: function(str){
return str + ':' + 'works!';
},
getFlags : function(){
$http({ method: 'GET', url: 'http://dalsapent01:8080/DataService/TestDataService.svc/EventTypes', headers: { 'Content-Type': 'application/json; charset=utf-8', 'dataType': 'json' } })
.success(function (data, status, headers, config) {
alert(data);
}).
error(function (data, status, headers, config) {
alert(data);
});
}
}
}])
when I look in fiddler, I see JSON being returned, but status is always 0. any Idea?
Thanks
I think you have a problem in your server response configuration.
Trying your code in this plunker, everything works fine.

ASP.Net MVC Get ID of newly added record from AJAX post

How do I retrieve the ID from the following model, after the following JQuery/Ajax posts to it:
JQuery:
$.ajax({
type: 'POST',
url: '/api/searchapi/Post',
contentType: 'application/json; charset=utf-8',
data: toSend,
}).done(function (msg) {
alert( "Data Saved: " + msg );
});
Controller:
// POST api/searchapi
public Void Post(Booking booking)
{
if (ModelState.IsValid)
{
tblCustomerBooking cust = new tblCustomerBooking();
cust.customer_email = booking.Email;
cust.customer_name = booking.Name;
cust.customer_tel = booking.Tel;
bc.tblCustomerBookings.Add(cust);
bc.SaveChanges();
long ID = cust.customer_id;
Return ID; <-- what do I enter here?
}
Return "Error"; <-- and here?
}
How can I get the ID back into the jQuery script, and if the model isn't valid, how do I return an error to the jQuery?
Thanks for any help,
Mark
You could return a JsonResult
[HttpPost]
public ActionResult Post(Booking booking)
{
if (ModelState.IsValid)
{
tblCustomerBooking cust = new tblCustomerBooking();
cust.customer_email = booking.Email;
cust.customer_name = booking.Name;
cust.customer_tel = booking.Tel;
bc.tblCustomerBookings.Add(cust);
bc.SaveChanges();
return Json(new { id = cust.customer_id });
}
return HttpNotFound();
}
and then on the client simply:
$.ajax({
type: 'POST',
url: '/api/searchapi/Post',
contentType: 'application/json; charset=utf-8',
data: toSend,
}).done(function (msg) {
alert('Customer id: ' + msg.id);
}).error(function(){
// do something if the request failed
});
One way to do it is like this:
In your controller:
public Void Post(Booking booking)
{
//if valid
return Json(new {Success = true, Id = 5}); //5 as an example
// if there's an error
return Json(new {Success = false, Message = "your error message"}); //5 as an example
}
In your ajax post:
$.ajax({
type: 'POST',
url: '/api/searchapi/Post',
contentType: 'application/json; charset=utf-8',
data: toSend,
success: function(result) {
if (result.Success) {
alert(result.Id);
}
else {
alert(result.Message);
}
}
});
returning void isn't a good idea, use JsonResult
Because you are using JavaScript, I recommend using JSON.
return this.Json(new { customerId = cust.customer_id});
In order to receive a return value, the controller method must return something other than void.
Does your controller compile? Your post method has a void return type, so it should fail compilation when it sees the return ID and return "Error" commands

X-editable with .Net and c# web methods

I am using X-Editable Plugin in Asp.net.
I have tried this: Usage with .Net and C# Webmethods
But it gives me error. It is not calling the WebMethod as it should be.
How to solve this problem?
Please help.
Javascript:
$('#username').editable({
url: function (params) {
return $.ajax({
url: 'Default.aspx/TestMethod',
data: JSON.stringify(params),
dataType: 'json',
async: true,
cache: false,
timeout: 10000,
success: function (response) {
alert("Success");
},
error: function () {
alert("Error in Ajax");
}
});
}
});
HTML:
superuser
WebMethod in Default.aspx:
[System.Web.Services.WebMethod]
public static String TestMethod(String params)
{
//access params here
}
If you want to call a page method, first of all you need to make a request of type POST (also having content-type set will not do any harm):
$('#username').editable({
url: function (params) {
return $.ajax({
type: 'POST',
url: 'Default.aspx/TestMethod',
data: JSON.stringify(params),
contentType: 'application/json; charset=utf-8',
dataType: 'json',
async: true,
cache: false,
timeout: 10000,
success: function (response) {
alert("Success");
},
error: function () {
alert("Error in Ajax");
}
});
}
});
Also the JSON will be auto deserialized on server side, so you should expect the name, pk and value parameters on server side (this is what plugin is sending according to docs)
[System.Web.Services.WebMethod]
public static String TestMethod(string name, string pk, string value)
{
//access params here
}
In your case the pk will be null as you haven't set one.

How to handle $.ajax

I want to send JSON data to an action that will update some data. I then want to either redirect to another action or send back an error message to $.ajax.
Is possible with $.ajax otherwise how can I?
Becase following code does not redirect.
[code]
[HttpPost]
public ActionResult Save(RecipeViewModel postdata)
{
Recipe recipe = postdata.GetRecipe(_user.UserID);
int recipeid = _service.AddRecipe(recipe, null, true);
foreach (Ingredient ing in recipe.Ingredients)
{
ing.RecipeID = recipeid;
_service.AddIngredient(ing, null, false);
}
if (!postdata.Comment.IsEmpty())
{
Comment comment = new Comment();
comment.fldComment = postdata.Comment;
comment.RecipeID = recipeid;
comment.UserID = _user.UserID;
comment.EnteredByName = _user.Names;
comment.EnteredOn = DateTime.Now.ToString();
_service.AddComment(comment, null, false);
}
_service.SubmitChanges();
return RedirectToAction("View", "Recipe", new { id = recipeid });
}
u<script type="text/javascript">
$("#Save").click(function () {
var ingredients = $("#ingredients tr.ingredientdata").map(function (element, index) {
return {
ingredientName: $("td.ingredient", this).text(),
units: $("td.units", this).text(),
measure: $("td.measure", this).text()
};
}).toArray();
var json = {
RecipeTitle: $("#recipetitle").val(),
CategoryID: $("#category").val(),
PrepTime: $("#prepTime").val(),
PrepTimePeriod: $("#lstPrepTime").val(),
CookTime: $("#cookTime").val(),
CookTimePeriod: $("#lstCookTime").val(),
Rating: $("#rating").val(),
Method: $("#method").val(),
Comment: $("#comment").val(),
AccessLevel: $("#accessLevel").val(),
Ingredients: ingredients
};
$.ajax({
url: "/Recipe/Save",
type: "POST",
dataType: 'json',
data: JSON.stringify(json),
contentType: "application/json; charset=utf-8",
success: function () {
//alert("DONE!!");
}
});
});
[/code]

You need to send back the Url and redirect it from the client script.
success: function (urlData) {
window.location.href = urlData ;
return false;
}
or you may show an error message based on the response received.
