how can i pass an array in window.location without ajax call

I want to send list array in ExportTo Method, but in ExportTo method student parameter get null value. If I use ajax it will work fine. But have to use window.locatoin for pass list array.
View
$(document).ready(function () {
$("#SaveBtn").click(function () {
var student = {
Name: "Tanzid",
Department: "CSE"
};
var student1 = {
Name: "Yasir",
Department: "BBA"
};
var list = [];
list.push(student);
list.push(student1);
var url = '#Url.Action("ExportTo", "Students")';
var a = JSON.stringify(list);
window.location = url + '?' + a;
});
})
.
Controller
Public void ExportTo(List<Student> student)
{
}

Iv'e tested some scenario of your problem and its work without using ajax:
Commented first your code coz i don't have it.
From Index View:
#{
ViewBag.Title = "Index";
}
<script src="~/scripts/jquery-1.10.2.js"></script>
<h2>Index</h2>
<script>
$(document).ready(function () {
var person = [];
person.push("Reign");//change like $("#idname").val();
person.push("John");
var listOfObjects = [];
person.forEach(function (names) {
var singleObj = {}
singleObj['name'] = names;
singleObj['dept'] = 'IT Dept.';
listOfObjects.push(singleObj);
});
var url = '#Url.Action("Sample", "Home")';
window.location = url + '?id=' + JSON.stringify(listOfObjects);
})
HomeController:
public ActionResult Sample()
{
string getval = Request.QueryString["id"];
string concat = #"{""data"":" + getval + "}";
ValList vl = new JavaScriptSerializer().Deserialize<ValList>(concat);
foreach (var item in vl.data)
{
Console.WriteLine("dept: {0}, name: {1}", item.dept, item.name);
}
return View();
}
public class ValList
{
public List<Values> data { get; set; }
}
public class Values
{
public string name { get; set; }
public string dept { get; set; }
}
It's all working its just depend on your project code with this:
//var List = [];
//var a = {
// Name: $("#").val(),
// Dept: $("#").val()
//};
//List.Push(a);
This is all i got..
It's Tested according to your needs.. Good Luck

[AngularJS][JavaEE] How to send multiple data with $http.post()

I work on a webapp, i have a probleme to send data and i didn't find some example. I use AngularJS and JavaEE.
Now :
AngularJs :
quiz is an object.
roomFactory.create = function(quiz){
//item.idLesson = $stateParams.lessonid;
return $http.post("/api/private/room/create",quiz)
.then(function (response){
roomFactory.room = response.data;
return roomFactory.room;
},function (response){
$q.reject(response);
});
};
Servlet :
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
//get the identity of the one who send the request
Map<String, Object> payload = AppConfig.getRequestPayload(request);
//objetMapper --> use to add request....
ObjectMapper objectMapper = new ObjectMapper();
Random randomGenerator;
// Number of question for the two sets
int nbQuestion = 0;
List<Question> questionsRandom = new ArrayList<>();
//Get object from request
//List<String> list = objectMapper.readValue(AppConfig.getJsonRequest(request), new TypeReference<List<String>>(){});
//List<Quiz> list2 = objectMapper.readValue(AppConfig.getJsonRequest(request), new TypeReference<List<Quiz>>(){});
//String name = list.get(0);
Quiz quiz = objectMapper.readValue(AppConfig.getJsonRequest(request),Quiz.class);
if (quiz.getDuration() == null) {
quiz.setDuration(-1);
}
//LOGGER.info("getIdLesson : ");
//Get list of question from datastore
List<Question> questions = ofy().load().type(Question.class).filter("idLesson", quiz.getIdLesson()).list();
//Take some questions from the list to make the quiz
if (!questions.isEmpty()) {
if (questions.size() < quiz.getNbQuestion()) {
nbQuestion = questions.size();
} else {
nbQuestion = quiz.getNbQuestion();
}
// we peek all the question randomly to the server and create a list of question
while (nbQuestion > 0) {
randomGenerator = new Random();
int index = randomGenerator.nextInt(questions.size());
questionsRandom.add(questions.get(index));
questions.remove(questions.get(index));
nbQuestion--;
}
if (!questionsRandom.isEmpty()) {
//Set the quiz
quiz.setQuestions(questionsRandom);
quiz.setNbQuestion(questionsRandom.size());
Lesson lesson = ofy().load().type(Lesson.class).id(Long.valueOf(quiz.getIdLesson())).now();
//Lesson lesson = ofy().load().type(Lesson.class).filter("idLesson", quiz.getIdLesson()).first().now();
//SET the room
//User user = ofy().load().type(User.class).id(Long.valueOf(jsonUserId.toString())).now();
User user = ofy().load().type(User.class).filter("email", payload.get("email").toString()).first().now();
//LOGGER.info("User : "+user.getFirstName());
Room room = new Room(user, quiz, 60);
room.calculTimeToFinishTheQuiz();
room.setName(lesson.getTitle() + RoomManager.roomNumber);
room.setId(quiz.getIdLesson() + RoomManager.roomNumber);
//Save the room in RoomManager
RoomManager.roomNumber++;
RoomManager.addNewRoom(quiz.getIdLesson(), room);
//Send the room in response
String json = objectMapper.writeValueAsString(room);
response.setContentType("application/json");
response.getWriter().write(json);
}
}
}
}
I need another parameter in my fonction create :
roomFactory.create = function(quiz, roomName){
I try this to send both data :
return $http.post("/api/private/room/create",quiz, roomName)
or
return $http.post("/api/private/room/create",[quiz, roomName])
Get data in Servlet :
first solution :
String roomName= objectMapper.readValue(AppConfig.getJsonRequest(request),String.class);
second solution :
List<String> list = objectMapper.readValue(AppConfig.getJsonRequest(request), new TypeReference<List<String>>(){});
String roomName = list.get(0);
roomName = roomName.replace("\"", "");
but the second didn't work because quiz is an object. I try to convert quiz but i didn't work as well.

You can pass multiple Data as follow
var Indata = {'pram1': 'value1', 'pram2': 'value2' };
$http.post("/api/private/room/create", Indata)
.then(function (response){
roomFactory.room = response.data;
return roomFactory.room;
},function (response){
$q.reject(response);
});
Here is the better example

For sending multiple list in the json to rest api use this code
var settings1 = {pram1: 'value1', pram2: 'value2',pram3: 'value3'};
var settings2 = {pram1: 'value1', pram2: 'value2',pram3: 'value3'};
var settings3 = {pram1: 'value1', pram2: 'value2',pram3: 'value3'};
var listObj = [settings1,settings2,settings3];
$http.post("/api/private/room/create",listObj)
.then(function (response){
roomFactory.room = response.data;
return roomFactory.room;
},function (response){
$q.reject(response);
});
and in the controller
#RequestMapping(value = "/api/private/room/create", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_VALUE)
ResponseEntity createRequest(#RequestBody List<SettingsModel> settingsList) {
}
SeetingsModel class is like this
public class SettingsModel {
private String param1;
private String param2;
private String param3;
public String getParam1() {
return param1;
}
public void setParam1(String param1) {
this.param1 = param1;
}
public String getParam2() {
return param2;
}
public void setParam2(String param2) {
this.param2 = param2;
}
public String getParam3() {
return param3;
}
public void setParam3(String param3) {
this.param3 = param3;
}
}

Download File From MVC

I need a way to pass a list of strings when a user clicks an icon from angular/script and send it to an MVC controller in .NET. This list does what it needs to then is supposed to download a file in my browser. I have learned that I cannot do this via AJAX and/or it get pretty messy.
Edit: the list of strings refers to a list of file ids that I am retrieving, then zipping up into one file, which is to be downloaded. I do not want to store this zipped file anywhere permanently.
I am open to ideas!
$http.post('document/downloadfiles', data).success(function () {/*success callback*/ });
[HttpPost]
public ActionResult DownloadFiles(List<string> fileUniqueIdentifiers)
{
var file = _service.ArchiveAndDownloadDocuments(fileUniqueIdentifiers);
file.Position = 0;
return new FileStreamResult(file, "application/force-download");
}

Ok, third-time lucky I guess?
(I think this'll be my last implementation sorry Jim - you'll have to work the rest out for yourself, I think I've given you more than enough free pointers for now... if you want more you can contact me and I'll charge you to write it! :P).
This version uses a cookie-based interchange, accepts the input strings (assuming they are filenames) from the javascript, stores these in the instance class along with the token as key, then assembles the ZipFile in-memory (without writing to disk), and then returns the zipfile as a Content Result. For efficiency you could remove the actual token checks against the GUID list and just check against the key in the file list. Obviously you probably won't want the filenames hard-coded in that javascript as I've done, but you can work that part out for yourself.
Hint: Create a database table with identifier/filepath pairs and use the identifiers to lookup the individual file paths after the request is sent to the server...
View Part (I added mine to index.cshtml):
<script type="text/javascript">
function sendStringandGetFiles() {
var files = ['c:\\temp\\afile.txt', 'c:\\temp\\afile2.txt', 'c:\\temp\\afile3.txt'];
$.ajax({
type: "POST",
url: "/Home/GetFile",
contentType: 'application/json',
data: JSON.stringify(files),
success: function (result) {
//alert("Yes This worked! - " + result);
window.location = "/Home/GetFile";
}
});
}
</script>
<h5>Just something to click</h5>
<button onclick="sendStringandGetFiles()">Send String and Get Files</button>
Then Controller Part (I used HomeController.cs)
[AcceptVerbs(HttpVerbs.Post)]
public string GetFile(string[] strings)
{
Guid token = Guid.NewGuid();
InMemoryInstances instance = InMemoryInstances.Instance;
instance.addToken(token.ToString());

HttpCookie cookie = new HttpCookie("CookieToken");
cookie.Value = token.ToString();
this.ControllerContext.HttpContext.Response.Cookies.Add(cookie);
return token.ToString();

return resultContent;
} else

return View("Index");
}

else
{
return View("Index");
}

Hope this helps!

I normally wouldn't go to this length of effort to help, but I'm home sick and feel like writing some code, so here's an implementation of what I think you're asking for. Here I'm using token exchange to track the file interchange for a specific user storing the data in a singleton instance, you could use another method (e.g. database token storage) if you wanted...
View Part (I added mine to index.cshtml):
<script type="text/javascript">
function sendStringandGetFiles() {
var strings = ['One String', 'Two String', 'Three String'];
$.ajax({
type: "POST",
url: "/Home/GetFile",
contentType: 'application/json',
data: JSON.stringify(strings),
success: function (result) {
//alert("Yes This worked! - " + result);
window.location = "/Home/GetFile?token=" + result;
}
});
}
</script>
<h5>Just something to click</h5>
<button onclick="sendStringandGetFiles()">Send String and Get Files</button>
Then, Controller part (I used HomeController.cs):
[AcceptVerbs(HttpVerbs.Post)]
public string GetFile(string[] strings)
{
for (int i = 0; i < strings.Length; i++)
{
// Do some stuff with string array here.
}
Guid token = Guid.NewGuid();
InMemoryInstances instance = InMemoryInstances.Instance;
instance.addToken(token.ToString());
return token.ToString();
}
[AcceptVerbs(HttpVerbs.Get)]
public ActionResult GetFile(string token)
{
string filename = #"c:\temp\afile.txt";
InMemoryInstances instance = InMemoryInstances.Instance;
if (instance.checkToken(token))
{
instance.removeToken(token);
FileStreamResult resultStream = new FileStreamResult(new FileStream(filename, FileMode.Open, FileAccess.Read), "txt/plain");
resultStream.FileDownloadName = Path.GetFileName(filename);
return resultStream;
}
else
{
return View("Index");
}
}
InMemoryInstances Class:
public class InMemoryInstances
{
private static volatile InMemoryInstances instance;

{
activeTokens.Add(new Guid(token));
return true;
}
public bool removeToken(string token)
{
return activeTokens.Remove(new Guid(token));
}
}
Hope this helps!

I also wrote yet another implementation which uses cookies to perform the same operation (incase you wanted to store the information client-side instead of using a query-string, yes, I'm slightly bored)...
View Part (I added mine to index.cshtml):
<script type="text/javascript">

FileStreamResult resultStream = new FileStreamResult(new FileStream(filename, FileMode.Open, FileAccess.Read), "txt/plain");
resultStream.FileDownloadName = Path.GetFileName(filename);
return resultStream;
} else
{
return View("Index");
}
}
else
{
return View("Index");
}
}
InMemoryInstances Class:
public class InMemoryInstances
{
private static volatile InMemoryInstances instance;
private static object syncRoot = new Object();
private List<Guid> activeTokens;

Maybe that is better if you want to hide the token interchange from the browser address bar?

JQuery request not working in Chrome and Firefox. Works in IE

I have a WCF service being hosted locally and a website also being hosted locally. I make a GET ajax request for JSON data which I handle on success. I have a problem where in Chrome and Firefox it goes into the error block of the Ajax request.
<!--jQuery dependencies-->
<link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.9.1/themes/base/jquery-ui.css" />
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.9.1/jquery-ui.min.js"></script>
<script type="text/javascript" src="../../Library/JS/pqgrid.min.js"></script>
<script type="text/javascript">
var jqNew = $.noConflict(true);
</script>
Because of the complexity of the website, I am using two different versions of JQuery. The newer version has the alias of jqNew.
jqNew(document).ready(function () {
$($.ajax({
url: "http://wks52025:82/WcfDataService.svc/GetNotesFromView()?$format=json",
type: "GET",
datatype: "json",
async: false,
success: function (data, textStatus) {
alert(textStatus);
$.each(data.d, function (i, item) {
alert(i);
DataArray[i] = [];
DataArray[i][0] = item.NotesID;
DataArray[i][1] = item.NotesTitle;
DataArray[i][2] = item.NotesText;
DataArray[i][3] = item.ProfileName;
DataArray[i][4] = item.IsShared;
DataArray[i][5] = item.NameOfUser;
});
},
error: function (data, textStatus) {
alert(textStatus);
}
})).then(buildGrid(DataArray));
This is my request. It is synchronous because I want the data before I build my grid. It is a GET request because all I want is to retrieve data. I am not doing a cross-domain request because everything is happening locally, at least I think it's local because the website and service is localhost.

This is my WCF service. Configuration is at the top of the code block.
Anyone know why this doesn't work in firefox and chrome?

How to call and pass values to a controller method from jquery

I have a http controller which is called from a getJSON method. Its working pretty good. But now I want to do the same operation performed in handler in a controller method. I am sending a value through getJSON to handler and it perform with that value.
Here is my getJSON
$(document).ready(function () {
$.getJSON('ProfileHandler.ashx', { 'ProfileName': 'Profile 1' }, function (data) {
$.each(data, function (k, v) {
alert(v.Attribute+' : '+v.Value);
});
});
});
and here is my handler
public void ProcessRequest(HttpContext context)
{
try
{
string strURL = HttpContext.Current.Request.Url.Host.ToLower();
//string ProfileName = context.Request.QueryString["profilename"];
string strProfileName = context.Request["ProfileName"];
GetProfileDataService GetProfileDataService = new BokingEngine.MasterDataService.GetProfileDataService();
IEnumerable<ProfileData> ProfileDetails = GetProfileDataService.GetList(new ProfileSearchCriteria { Name = strProfileName });
JavaScriptSerializer javaScriptSerializer = new JavaScriptSerializer();
string strSerProfileDetails = javaScriptSerializer.Serialize(ProfileDetails);
context.Response.ContentType = "text/json";
context.Response.Write(strSerProfileDetails);
}
catch
{
}
}
how can I call and pass 'ProfileName' to a controller method ?

Your code is correct and you should be able to retrieve the ProfileName with the following:
string strProfileName = context.Request["ProfileName"];
And if you wanted to pass it to a controller action simply define this action:
public ActionResult SomeAction(string profileName)
{
var profileDataService = new BokingEngine.MasterDataService.GetProfileDataService();
var request = new ProfileSearchCriteria { Name = profileName };
var profileDetails = profileDataService.GetList(request);
return Json(profileDetails, JsonRequestBehavior.AllowGet);
}
and then invoke your controller action with AJAX:
<scirpt type="text/javascript">
$(document).ready(function () {
var url = '#Url.Action("SomeAction")';
$.getJSON(url, { profileName: 'Profile 1' }, function (data) {
$.each(data, function (k, v) {
alert(v.Attribute + ' : ' + v.Value);
});
});
});
</script>

You almost have it. Here is an example:
Javascript
function someFunction(e) {
$.post("#Url.Action("MethodName", "ControllerName")", { ParameterName: e.value }, function(data) {
$("#someDiv").html = data;
});
}
C# Controller
[HttpPost]
public ActionResult MethodName(string ParameterName)
{
return "Hello " + ParameterName;
}
If you passed in your name to the JavaScript function "someFunction", the controller would return "Hello [your name]". Help?
