i'm trying to connect from html page to web method with ajax function
$.ajax({
url: "http://localhost:43599/WebForm1.aspx/GetWeatherResultsbyscript",
cache: false,
type: "POST",
contentType: "application/json; charset=utf-8",
data:{Zip:input},
dataType: 'json',
success: function (data,result) {
alert(result.d);
},
error: function () { alert(" Server not found"); }
});
[System.Web.Services.WebMethodAttribute(), System.Web.Script.Services.ScriptMethodAttribute()]
private object GetWeatherResultsbyscript(string Zip) {
ServiceReference1.ForecastReturn result = new ServiceReference1.ForecastReturn();
ServiceReference1.WeatherSoapClient client = new ServiceReference1.WeatherSoapClient();
result = client.GetCityForecastByZIP(Zip);
return (result);
}
As a result i'm getting that server is not found, but if i delete to rows in ajax function
contentType: "application/json; charset=utf-8",
dataType: "json",`
i'm getting 'undefined' as a result.
Can anyone tell what i did wrong in this implication of connection to web method?
The method should be public. Try the code below,
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public object GetWeatherResultsbyscript(string Zip) {
ServiceReference1.ForecastReturn result = new ServiceReference1.ForecastReturn();
ServiceReference1.WeatherSoapClient client = new ServiceReference1.WeatherSoapClient();
result = client.GetCityForecastByZIP(Zip);
return (result);
}
Also,
The application name is missing in the URL: http://localhost:43599/application name/WebForm1.aspx

I'm currently working on an ASP.Net MVC project.
I have a JavaScript function which takes an XML string as input. I would like to send this to the controller.
I have done so using an AJAX request, but in the controller the string is null.
View:
function save() {
var xml = scheduler.toXML();
alert(xml);
var url = '#Url.Action("Save", "Home")'
$.ajax({
url: url,
Type: "POST",
dataType: 'json',
async: false,
data: xml,
contentType: 'application/json; charset=utf-8',
success: function (data) { alert("OK");},
error: function (jqXHR, exception) {
alert('Error message.');
}
});
Controller:
public ActionResult Save(string xml)
{
Console.WriteLine(xml);
W6ViewModel viewModel = new W6ViewModel();
viewModel.engineers = db.W6ENGINEERS.ToList();
viewModel.tasks = db.W6TASKS.ToList();
viewModel.skills = db.W6TASKS_REQUIRED_SKILLS1.ToList();
var engList = new List<object>();
foreach (var engineer in viewModel.engineers)
{
engList.Add(new { key = engineer.ID, label = engineer.Name });
}
ViewBag.engineers = engList;
return View("Index", viewModel);
}
var xml = scheduler.toXML()
alert(xml):
Error Code (Sorry, wall of text):
[HttpRequestValidationException (0x80004005): A potentially dangerous Request.QueryString value was detected from the client (xmlString="<data><event>
Name your parameter like this:
function save() {
var xml = scheduler.toXML();
alert(xml);
var url = '#Url.Action("Save", "Home")';
$.ajax({
url: url,
Type: "POST",
dataType: 'json',
async: false,
data: { xml: xml},
contentType: 'application/json; charset=utf-8',
success: function (data) { alert("OK");},
error: function (jqXHR, exception) {
alert('Error message.');
}
});
Also put this tag above you controller action:
[ValidateInput(false)]
See the following ajax call:
$.ajax({
url: '#Url.Content("~/myaccount/CheckDuplicateEmailAddress")',
data: { "emailAddress": email },
async: false,
type: "post",
success: success,
error: error
});
And controller action is below. you need to send param as this:
data: { "emailAddress": email }
Remember case sensitivity and double quotes:
public bool CheckDuplicateEmailAddress(string emailAddress)
{
}
I am trying to post to a method using jQuery and Ajax. My Ajax code is as follows:
var isMale = $(e.currentTarget).index() == 0 ? true : false;
$.ajax({
type: "POST",
url: "Default.aspx/SetUpSession",
data: { isMale: isMale },
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function() {
// Go to next question
}
});
And here is my WebMethod:
[WebMethod]
public static void SetUpSession(bool isMale)
{
// Do stuff
}
I get a 500 (Internal Server Error) looking at the console, the method never get's hit. After I changed data to "{}" and removed the bool from the method signature the method then gets hit, so I'm assuming its something to do with the Ajax.data attribute I'm trying to pass.
Two things you need to modify :-
1) Make sure that this line is written in your web service page and should be uncommented.
[System.Web.Script.Services.ScriptService]
2) Modify the "data" in the code as :-
$.ajax({
type: "POST",
url: "Default.aspx/SetUpSession",
data: '{ isMale:"' + isMale + '"}',
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function() {
// Go to next question
}
});
Pass string instead of bool
[WebMethod]
public static void SetUpSession(string isMale)
{
// Do stuff
}
Alternative you can use pagemethods through script manager.
Try following code:
var params = '{"isMale":"' + $(e.currentTarget).index() == 0 ? true : false + '"}';
$.ajax({
type: "POST",
url: "Default.aspx/SetUpSession",
data: params,
contentType: "application/json; charset=utf-8",
dataType: "json",
responseType: "json",
success: function (data) {}
});
[WebMethod]
public static void SetUpSession(string isMale)
{
// Do stuff
}
I'm building a Web Application in which I'm trying to call a WebMethod in a WebForm, I've tried every single page in google but I'm still getting nothing. This is an example of the Jquery Ajax Call
$.ajax({
type: "Post",
url: "Default.aspx/Return",
data: {dato:'Hello'},
contentType: "application/json; chartset:utf-8",
dataType: "json",
success:
function (result) {
if (result.d) {
alert(result.d);
}
},
error:
function (XmlHttpError, error, description) {
$("#grdEmpleados").html(XmlHttpError.responseText);
},
async: true
});
And this is the WebMethod in the codebehind
[WebMethod]
[ScriptMethod(ResponseFormat=ResponseFormat.Json)]
public static string Return(string dato)
{
return dato;
}
You can't access a Static method this way. Remove the "Static" reference and it will work. Also, like someone else said - do not use that as your method name "Return".
[WebMethod]
[ScriptMethod(ResponseFormat=ResponseFormat.Json)]
public string Return(string dato)
{
return dato;
}
I think, on your success event the function with result is used, which is a string and u are trying to access property named d assuming result is an object.
use of only alert(result);
User F12 tool to debug and find your error.
Make sure that you have enabled page methods in your ScriptManager element:
<asp:ScriptManager ID="scriptManager" runat="server" EnablePageMethods="true" />
and your method
$.ajax({
type: "Post",
url: '<%= ResolveUrl("~/Default.aspx/Return") %>',
data: {dato:'Hello'},
contentType: "application/json; charset=utf-8",
dataType: "json",
success:
function (result) {
alert(result);
},
error:
function (XmlHttpError, error, description) {
$("#grdEmpleados").html(XmlHttpError.responseText);
},
async: true
});
Try this
var url = window.location.pathname + "/Return";
$.ajax({
type: "Post",
url: url,
data: {dato:'Hello'},
contentType: "application/json; charset=utf-8",
dataType: "json",
success:
function (result) {
alert(result.d);
},
error:
function (XmlHttpError, error, description) {
$("#grdEmpleados").html(XmlHttpError.responseText);
},
async: true
});`
In my MVC3 app, I'm using $.ajax to call a method of type JsonResult to get data to be displayed:
function GetData(e) {
var ordersId = e.row.cells[0].innerHTML; //this is fine
$.ajax({
type: "POST",
url: "/Documents/GetDocumentData",
contentType: "application/json; charset=utf-8",
data: "{'id': '"+ordersId +"'}",
dataType: "json",
success: function (result) {
//load window
},
error: function (result) {
if (!result.success)
//show error
}
});
This is my Action:
[HttpPost]
public JsonResult GetDocumentData(string id)
{
//my code
return Json(new { success = true});
}
When im debugging on my development machine, it works fine. I deployed it to my test web server and i get '404 page not found dev/testwebsite/Documents/GetDocumentData' I should get this when debugging if something was wrong, but i dont. Why am I getting this error? Thanks
Your URL in the javascript is wrong, if that dev/testwebsite/Documents/GetDocumentData is the URL on the server.
You should be using #Url.Action() to automatically form those URLs in the cshtml page.
Example:
#Url.Action("actionName","controllerName" )
So, for your specific case, it would be:
#Url.Action( "GetDocumentData", "Documents" )
In the javascript, it would look like this:
function GetData(e) {
var ordersId = e.row.cells[0].innerHTML; //this is fine
$.ajax({
type: "POST",
url: '#Url.Action("GetDocumentData","Documents")',
contentType: "application/json; charset=utf-8",
data: "{'id': '"+ordersId +"'}",
dataType: "json",
success: function (result) {
//load window
},
error: function (result) {
if (!result.success)
//show error
}
});
I am getting a problem in calling a webmethod inside my http handler. The jquery.js file opens up at some random place and gives a prompt "Invalid Argument"
Code is as follows:
JS:
var src = "MyHandler.axd";
var id = "1234566";
$.ajax({
type: "GET",
contentType: "application/json; charset=utf-8",
url: src + "/MyMethod?key=" + id,
success: function (msgObj) {
var msg = msgObj.d;
},
error: function (e) {
alert("Error");
}
});
C#
[System.Web.Services.WebMethod(EnableSession = true)]
[System.Web.Script.Services.ScriptMethod(UseHttpGet = true, ResponseFormat = ResponseFormat.Json)]
public static string MyMethod(string key)
{
return someLogic;
}
And because of which the ProcessRequest method is being called for the ajax call.
Even tried it with following
Removed httpget and responseformat from c# code.
JS
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: src + "/MyMethod",
data: "{ 'key':'"+ id +"'}",
dataType: "json",
success: function (msgObj) {
debugger;
var msg = msgObj.d;
},
error: function (e) {
debugger;
}
});
Well, not able to find any solution or reason why this behavior!
Kept the same webmethod in a page and its working fine. So added logic to handle the ajax call in process request only. works like a charm.
