Hi Guys,
For some reason, I'm only able to pass strings containing numbers to my web service when using jquery ajax. This hasn't been an issue so far because I was always just passing IDs to my wcf service. But I'm trying to do something more complex now but I can't figure it out.
In my interface:
[OperationContract]
[WebInvoke(ResponseFormat = WebMessageFormat.Json)]
DataTableOutput GetDataTableOutput(string json);
My webservice:
public DataTableOutput GetDataTableOutput(string json)
{
DataTableOutput x = new DataTableOutput();
x.iTotalDisplayRecords = 9;
x.iTotalRecords = 50;
x.sColumns = "1";
x.sEcho = "1";
x.aaData = null;
return x;
}
Javascript/Jquery:
var x = "1";
$.ajax({
type: "POST",
async: false,
url: "Services/Service1.svc/GetDataTableOutput",
contentType: "application/json; charset=utf-8",
data: x,
dataType: "json",
success: function (msg) {
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
//alert(XMLHttpRequest.status);
//alert(XMLHttpRequest.responseText);
}
});
The above code WORKS perfectly. But when I change x to "t" or even to "{'test':'test'}" I get a Error 400 Bad Request error in Firebug.
Thanks,
John
EDIT:
Making some progress!
data: JSON.stringify("{'test':'test'}"),
Sends the string to my function!
EDIT2:
var jsonAOData = JSON.stringify(aoData);
$.ajax({
type: "POST",
async: false,
url: sSource,
contentType: "application/json; charset=utf-8",
data: "{'Input':" + jsonAOData + "}",
dataType: "json",
success: function (msg) {
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
//alert(XMLHttpRequest.status);
//alert(XMLHttpRequest.responseText);
}
});
EDIT3: I modified the code block I put in EDIT2 up above.
Swapping the " and ' did the trick!
$.ajax({
type: "POST",
async: false,
url: sSource,
contentType: "application/json; charset=utf-8",
data: '{"Input":' + jsonAOData + '}',
dataType: "json",
success: function (msg) {
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
//alert(XMLHttpRequest.status);
//alert(XMLHttpRequest.responseText);
}
});
However, I have a new problem:
public DataTableOutput GetDataTableOutput(DataTableInputOverview Input)
{
The input here is completely null. The values I passed from jsonAOData didn't get assigned to the DataTableInputOverview Input variable. :(
