is it possible to call a webservice that accepts 5 string parameters without sending via json? (is this recommended) I have created a webservice with a method that accepts 5 string params.. and i have my jquery
$.ajax({
type: "POST",
url: "Service.aspx/CreateClient",
data: "{}",
contentType: "application/json; charset=utf-8", //// ERMMM ???
dataType: "json", // ERMMM?
success: function(msg) {
alert(msg.d);
},
error: function() {
alert('error');
}
});
The old way without using jquery was to do this
this.para.add("Name", name);
this.para.add("ClientNum", clnum);
this.para.add("Email", email);
this.para.add("Register", register);
this.para.add("Message", message);
SOAPClient.invoke(this.url, "MyService.aspx/CreateClient", this.para, true, this.completeDone, this);
At the other end it lands and fills in all parameters....
What is the recommended way?
why not use querystring variables and avoid the overhead of the SOAP protocol?

I am using vb.net 2.0 and asp.net in my project.
I am sending ajax request from a page to get response.
$.ajax({
type: "POST",
url: "GetMyData.aspx?i=2",
data: '{ugData: \"10\"}',
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (response) {
alert(response.d);
return false;
},
failure: function (response) {
alert("Failed");
}
});
In this code, after ajax request I can see that the variable "ugData" is in the Request Payload in Developers tool.
Can any one help me out How can i able to read this "ugData" variable value in my Page "GetMyData.aspx".
Thank You..
i am going to develop a new application and i have decided to use asp.net mvc4 framework.
my project is very large and i would to make a professional work,now my problem is how to use ajax for such an application.
when i tried to think to use j query ajax i found that i'll make ajax request for each entry form and it would take more time.
<script type="text/javascript">
$(document).ready(function () {
var sURL = '/AjaxTest/FirstAjax';
$.ajax({
type: "POST",
url: sURL ,
data: {
//Form data to submit to controller .....},
contentType: "application/json; charset=utf-8",
dataType: "json",
success: successFunc,
error: errorFunc
});
function successFunc(data, status) {
alert(data);
}
function errorFunc() {
alert('error');
}
});
</script>
You can make some service function that does ajax requests and receives url and data to send.
dataService=function(url,data)
{
return $.ajax({
type: "POST",
url: url ,
data: data
contentType: "application/json; charset=utf-8",
dataType: "json",
});
};
Your dataservice method (ajax requests) returns promise object which means you can do something like:
dataService("firstUrl","firstAjaxCallData")
.then(function(){ console.log("this happens after sucessfull ajax call")});
I would like consume cross-domain web-service from client with jquery.here is my code
function getId() {
var testid = ($('#<%=PreviousTest.ClientID %> OPTION:selected').val());
jQuery.support.cors = true;
jQuery.ajax({
type: "POST",
url: "../FalconWebService.asmx/minlatency",
data: "{'testId':" + testid + "}",
contentType: "application/json; charset=utf-8",
dataType:"json",
success: function (data) {
alert("catch");
var msg = jQuery.parseJSON(data.Table);
return msg;
},
Error: function () {
alert("error");
}
my webservice returns values in this format
{"Table":[{"minlatency":16.0,"Time":"/Date(1328248782660+0530)/"},{"minlatency":7.0,"Time":"/Date(1328248784677+0530)/"},{"minlatency":13.0,"Time":"/Date(1328248786690+0530)/"},{"minlatency":6.0,"Time":"/Date(1328248788690+0530)/"},{"minlatency":20.0,"Time":"/Date(1328248790707+0530)/"},{"minlatency":12.0,"Time":"/Date(1328248792723+0530)/"},{"minlatency":26.0,"Time":"/Date(1328248794723+0530)/"},{"minlatency":18.0,"Time":"/Date(1328248796723+0530)/"}]}
Calls in cross-domain work in a different way. They create dynamic javascripts that are inserted to the page using a callback function. This function is used to handle the response from the service. The Jquery calls add a "?callback=?" to the URL of the service, where "callback" is the name of the function that will be inserted.
To call cross-domain services with JQuery you have to do the following:
jQuery.ajax({
type: "POST",
url: "../FalconWebService.asmx/minlatency",
data: "{'testId':" + testid + "}",
contentType: "application/json; charset=utf-8",
dataType: "jsonp", //The data type that you must use is JSONP. Basically tells JQuery that the request is cross-domain
success: function (data) {
alert("catch");
var msg = jQuery.parseJSON(data.Table);
return msg;
},
Error: function () {
alert("error");
},
jsonpCallback: 'callback' //Dude to the fact that the JS is being generated dynamicaly, this tells JQuery to use the name "callback" for the function that will handle the result, as it adds "?callback=?" to the URL
});
You could also use "jsonp" instead of "jsonpCallback" if you want to "override the callback function name in a jsonp request" (from JQuery).
It worked for me (in WCF REST services which communicate with JSON messages, but it should work the same way in your case). This is all explained in the JQuery Ajax documentation.
Hope this helps.
I am simply learing Ajax with jQuery and have a simple page method that takes in a parameter and returns a string. For some reason, I am not getting the return string but I am getting to my 'success' message:
$(document).ready(function() {
$.ajax({
type: "POST",
url: "testFormMatt.aspx/sayHello",
contentType: "application/json; charset=utf-8",
data: '{"name": "matt"}',
dataType: "json",
success: function(msg) {
$.jGrowl('The web service has been successfully called');
$('#result').append(msg);
}
});
});
When you call append, you need to specify the property of the JSON object that you want to append.
So if your page is returning:
{ message: "Hello, Matt" }
Then you'd need to call append like this:
$("#result").append(msg.message);
If your page is not returning JSON, then you need to take the dataType: "json" out of the $.ajax call. The dataType parameter is for specifying the expected data type of the response, not the data type of the request.
I have in my javascript these 2 functions "classes":
// product class
function Product() {
this.id;
this.qty;
this.size;
this.option;
}
// room class
function Room() {
this.id;
this.type;
this.products = [];
}
I have my js logic which fills rooms and their products.
Now i want to send array of rooms to a webservice to do some calculations and get back from it the result.
How to send this array objects to the service and whats the data type which the service will receive to loop through and process?
I tried to write the javascript code like this:
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "_Services/MyWebService.asmx/CalculatePrices",
data: "{'rooms':'" + roomsObjects + "'}",
dataType: "json",
success: function(result) {
alert(result.d);
}
});
And the webservice like this:
[WebMethod]
public string CalculatePrices(object rooms)
{
return "blabla";
}
but i find that rooms in the wbservice is always = [object Object]
For that case this would work:
//...
data : '{"rooms":[' + roomsObjects.join() + ']}',
//...
The above code will generate a valid JSON string, but I recommend you to get a JSON library and use JSON.stringify function:
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "_Services/MyWebService.asmx/CalculatePrices",
data: JSON.stringify({'rooms': roomsObjects}),
dataType: "json",
success: function(result) {
alert(result.d);
}
});
If you don't mind including a tiny JavaScript library, I think using json2.js' JSON.Stringify is the best way to serialize objects for use with ASP.NET AJAX services.
Here's a snippet from that post:
// Initialize the object, before adding data to it.
// { } is declarative shorthand for new Object().
var NewPerson = { };
NewPerson.FirstName = $("#FirstName").val();
NewPerson.LastName = $("#LastName").val();
NewPerson.Address = $("#Address").val();
NewPerson.City = $("#City").val();
NewPerson.State = $("#State").val();
NewPerson.Zip = $("#Zip").val();
// Create a data transfer object (DTO) with the proper structure.
var DTO = { 'NewPerson' : NewPerson };
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "PersonService.asmx/AddPerson",
data: JSON.stringify(DTO),
dataType: "json"
});
There's no array in that example, but JSON.Stringify does serialize JavaScript arrays in the correct format to send in to ASP.NET AJAX services for array and List parameters.
A nice thing about using JSON.Stringify is that in browser that support native JSON serializing (FF 3.5, IE 8, nightly builds of Safari and Chrome), it will automatically take advantage of the browser-native routines instead of using JavaScript. So, it gets an automatic speed boost in those browsers.
Change:
data: "{'rooms':'" + roomsObjects + "'}",
to:
data: {'rooms':roomsObjects},
