I'm in need of a code example here :/ I'm trying to get a jsonp call to work.
This is my code on jquery:
$.ajax({
crossDomain:true,
url: "the_server_url",
type: "POST",
data: {
numberOfUnits:10,
unitType:"u",
language:"eng-us",
genderAndAge:"MiddleAgeAnyGender",
script:"",
synced_recording:0,
secret:0,
numAuditions:0
},
dataType: "jsonp",
success: function(text) {
alert("Text: "+text);
},
error: function(request,error)
{
alert("err: "+error);
alert ( " Can't do because: " + JSON.stringify(request));
alert("response text: "+request.responseText);
}
});
And this is what I get:
alert #1: err: parsererror
alert #2: Can't do because: {"readyState":4,"status":200,"statusText":"success"}
alert #3: response text: undefined
I don't have access to the server code. Any ideas? Thank you!

I tried to integrate the diagram viewer in my webapp. The error happend while loading the page http://localhost:8080/MyActiviti/diagram-viewer/index.html?processDefinitionId=myProcess:1:4&processInstanceId=10001
The following is error info, I haved checked the json format of responseText, any other solutions?
Just comment dataType line in ActivitiRest.js.There should be three positions.
like this:
$.ajax({
url: url,
//dataType: 'jsonp',
cache: false,
async: true,
success: function(data, textStatus) {
var processDefinition = data;
if (!processDefinition) {
console.error("Process definition '" + processDefinitionKey + "' not found");
} else {
callback.apply({processDefinitionId: processDefinition.id});
}
}
}).done
I need this part of my url:
"Regular+Season" printed as "Regular+Season" instead of "Regular%2BSeason" to the console.
I have currently developed a ajax function and I keep getting invalid syntax errors due to this issue
Ajax code:
function loadStats() {
$.ajax({
url: 'http://stats.nba.com/stats/leagueLeaders?&callback=?',
jsonpCallback: 'jsonReturnData',
dataType: 'jsonp',
data: {
LeagueID: '00',
PerMode: 'PerGame',
Scope: 'S',
Season: '2016-17',
SeasonType: 'Regular+Season',
StatCategory: 'PTS',
format: 'json'
},
success: function(response) {
console.log(response);
}
I have tried this alot but always I am getting the failure problem .Can any one guide how can we read the json file using jQuery?I have a json file in my project as given in this image
i have written the code as given below
$(document).ready(function () {
$('#btnLoad').click(function () {
$.ajax({
url: "example.json",
dataType: "text/json",
type: "GET",
contentType: "application/json;charset=utf-8",
success: function (msg) {
AjaxSucceeded(msg);
},
error: AjaxFailed
});
});
});
function AjaxSucceeded(result) {
alert(result.d);
}
function AjaxFailed(result) {
alert(result.status + ' ' + result.statusText);
}
But It is always AjaxFailed is firing.
dataType should be 'JSON'
There are only 4 accepted values for dataType, which you can see here:
http://docs.jquery.com/Specifying_the_Data_Type_for_AJAX_Requests
Also, your error function takes 3 parameters:
errorFn(jqXHR, textStatus, errorThrown) {
// your code
}
Additionally, this:
success: function (msg) {
AjaxSucceeded(msg);
},
Can be this:
success: AjaxSucceeded
Your success function also takes 3 parameters:
success(data, textStatus, jqXHR)
For reference on $.ajax parameters: http://api.jquery.com/jQuery.ajax/
When I debug using Firebug I see the control jumping to error section after hitting success. I am unable to find out what is going wrong. Can some body please point out what is wrong with this code.
$(function(){
$.ajax({
type: "POST",
url: "service/MyService.asmx/GetAsgInfo",
data: "{id: " + parseInt($('#AsgId').val()) + "}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (msg) {
// var s = eval('(' + msg.d + ')');
alert(msg.d[0].SubmittedCount);
},
error: function (e) {
alert("error : " + e);
}
});
});
POST :
{id: 5301}
RESPONSE :
{"d":[{"__type":"Proxies.AFARServiceRef.AssignmentInfo","ExtensionData":
{},"AssignDate":"\/Date(1319526000000)\/","AssignFileName":null,"ClaimId":"MH001025","ClaimantName":"Deborah C Plaid","FirstContactDate":"\/Date(1319526000000)\/","FirstContactTime":
{"Ticks":420000000000,"Days":0,"Hours":11,"Milliseconds":0,"Minutes":40,"Seconds":0,"TotalDays":
0.4861111111111111,"TotalHours":11.666666666666666,"TotalMilliseconds":42000000,"TotalMinutes":700,"TotalSeconds":42000},"Id":5301,"InspectionDate":"\/Date(1319612400000)\/","StatusId":1,
"SubmittedCount":4,"UploadedCount":14}]}
Instead of using the success and error functions, try using complete:
complete: function(jqXHR, textStatus) {
alert(textStatus);
}
I had a similar problem with handling json, and it turns out I wasn't setting the content-type properly on the server side. Even valid json sometimes causes weird errors when it is in a response labeled as "text/plain" or even "text/json". Make sure your content type is right.
I am trying to get JQueryUI's Autocomplete code working with an ASMX web service. I am getting close, but hit yet another wall yesterday. The JSON data is being returned in {d:"data"} format (see http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx). My data now looks like:
d: "[{"DOTNumber":"001061010","JobTitle":"Project Architect"},{"DOTNumber":"003061005","JobTitle":"Principal Electrical Engineer"}]"
My code is:
$(function() {
function log(message) {
$("<div/").text(message).prependTo("#log");
$("#log").attr("scrollTop", 0);
}
});
$("#dotmatch").autocomplete({
source: function(request, response) {
$.ajax({
type: "POST",
url: "/AutoSuggestJSTest/AutoSuggest.asmx/DOTFind",
contentType: 'application/json',
dataType: "json",
data: JSON.stringify({ prefixText: request.term, count: 20 }),
error: function(XMLHttpRequest, textStatus, errorThrown) {
alert(textStatus);
},
success: function(data) {
var safe = data;
response($.map(safe.d, function(item) {
return {
label: item.JobTitle + "(" + item.DOTNumber + ")",
value: item.DOTNumber
}
}));
}
});
},
minLength: 2,
select: function(event, ui) {
log(ui.item ?
"Selected: " + ui.item.value + " aka " + ui.item.id :
"Nothing selected, input was " + this.value);
$get("DOTNumber").value = ui.item.value;
},
});
The problem lies in the success function.
What is the right syntax to get past the "d" issue?
Your data should look like this:
{"d":[{"DOTNumber":"001061010","JobTitle":"Project Architect"},"DOTNumber":"003061005","JobTitle":"Principal Electrical Engineer"}]}
It appears you are missing quotes around your "d" and you have extra quotes around your array.
Don't eval() your data - this opens you up to more security issues than the d: prevented.. You should have access to JSON.parse() or if not jQuery.parseJSON() (which wraps JSON.parse() if available... depends on your target platform(s)).
This has been an incredibly difficult process, but I finally got it working. There were a number of hurdles:
1) My JSON return string was getting wrapped in an XML blanket, so it would not parse
2) Solving this problem required the contentType: 'application/json' line
3) With that content type, a POST was required. GET would not work
4) POST required putting the data together using the JSON.stringify. I am still not sure about this one, but I found some code somewhere that did it.
5) Data coming back from the POST was prefixed with a "d " (see: http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
6) getting access to the data itself required the "eval(data.d)" line.
$("#dotmatch").autocomplete({
source: function(request, response) {
$.ajax({
type: "POST",
url: "/AutoSuggestJSTest/AutoSuggest.asmx/DOTFind",
contentType: 'application/json',
dataType: "json",
data: JSON.stringify({ prefixText: request.term, count: 20 }),
success: function(data) {
var output = eval(data.d);
response($.map(output, function(item) {
return {
label: item.JobTitle + "(" + item.DOTNumber + ")",
value: item.DOTNumber
}
}));
},
error: function(XMLHttpRequest, textStatus, errorThrown) {
alert(textStatus);
}
});
},
minLength: 2
});
If I ever have this much trouble writing a few lines of code again, I am going to take a very large guage shotgun to my computer!

If you use a WCF JSON service with the webHttpBehavior (instead of enableWebScriptBehavior), it will not emit the "d"
