I'm trying to make a cross domain ajax request to deezer, a music streaming api... and I'm getting an "Uncaught SyntaxError: Unexpected token :" error. I know it's because the data I'm getting back is not in proper json format, but I tried changing the datatype to 'json' from 'jsonp' and it's still not working...here's my request, any suggestions?
$.ajax({
url: "https://api.deezer.com/search?q=" + searchString + "&callback=?",
dataType: 'json',
jsonpCallback: 'callback',
type: 'GET',
success: function (data) {
console.log(data);
}
});
This is because you used unencoded second "?" in your url after first "?", which using for separate get-string. You need to remove this part of url + "&callback=?".

I made this function to request some tickets from JIRA,I gave the data type as jsonp to avoid the Cross origin problem , and when I make the request I get the response in browser debugger , but cannot handle the json response "SyntaxError: missing ; before statement" , is there any way to read json if I send the request for jsonp ?
var ajaxUrl = jira/rest/api...
jQuery.ajax({
url:ajaxUrl,
dataType: 'jsonp',
jsonpCallback: 'callback',
type : "GET",
beforeSend: function (xhr){
success: function w(data){
console.log(data);
alert('Sucess data: ' + data);
};
error: function e(data){alert('alert error');}
}
})
I solved the problem , I changed the jsonp in json , and I remade the corss from jira server how it is explained here : https://community.atlassian.com/t5/Answers-Developer-Questions/Enable-CORS-in-JIRA-REST-API/qaq-p/553997 , it looks like the problem was on the preflight part.
I am trying to pull a password protected xml feed from another website, but I am getting the following error:
"Uncaught SyntaxError: Unexpected token <"
I fixed the origin access error that I was getting previously by adding a callback function, but now I am getting this uncaught syntax error.
My code is:
$.ajax({
url: 'http://xxx.php?&callback=?',
dataType: 'jsonp',
type: 'POST',
username: 'xxxxx',
password: 'xxxxx',
crossDomain : true,
xhrFields: {
withCredentials: true
}
});
When I inspect the error I can just see 'denied' where the feed should be: screen shot of error
Any ideas why this is not working? Do I need to request something from the feed provider? Or is there something missing/incorrect in my code?
You try to load an xml and use dataType: 'jsonp'. jQuery can't handle the response because you tell the $.ajax function to use the response as JSONP. So the first char of the response < is unexpected.
Use dataType: 'xml' instead.
The denied seems to come from a wrong login too. Are you sure the username and password options are working for you? I got many problems using it this way. I would pefer to change your login to use beforeSend, like this:
$.ajax({
url: 'http://xxx.php?&callback=?',
dataType: 'xml',
type: 'POST',
crossDomain : true,
xhrFields: {
withCredentials: true
},
beforeSend: function (xhr) {
xhr.setRequestHeader('Authorization', 'Basic ' + btoa('username:password'));
}
});
I am trying to do a GET request to solr search engine using $.ajax() from jQuery. This is the code I am using for doing an ajax call:
$.ajax({
url : 'http://xxx.xxx.xxx.xxx:port#/solr/mycore/select?indent=on&q=myparam:value&wt=json',
type: "GET",
dataType: "jsonp",
jsonp : "callback",
success: function(data) {
console.log("Success", data);
},
error: function(data) { alert("Error"); }
});
So I am getting a valid json object in the response but somehow the browser throws an Uncaught Syntax Error. The actual error is:
Uncaught SyntaxError: Unexpected token :
select?indent=on&q=myparam:value&wt=json&callback=…....somevalue...
The tricky part is that the response header is text/plain when I checked in the browser. How can I solve this? Please help me...
Colons require encoding in query strings.
Your url should look like this:
http://xxx.xxx.xxx.xxx:port#/solr/mycore/select?indent=on&q=myparam%3Avalue&wt=json
If you're generating the query string dynamically, use encodeURIComponent() to correctly encode special characters.
I got this solved. Actually I had to use jsonpCallback:"mysuccesscallbackfunction" in the ajax call and json.wrf=mysuccesscallbackfunction in the URL. It looks like this now:
$.ajax({
url : 'http://xxx.xxx.xxx.xxx:port#/solr/mycore/select?indent=on&q=myparam:value&wt=json&json.wrf=mysuccesscallbackfunction',
type: "GET",
dataType: "jsonp",
jsonp : "callback",
jsonpCallback:"mysuccesscallbackfunction",
success: function(data) {
console.log("Success", data);
},
error: function(data) { alert("Error"); }
});
and my mysuccesscallbackfunction is:
function mysuccesscallbackfunction(resp) {
console.log('inside mysuccesscallbackfunction: ', resp );
}
Now, first it executes whatever is inside mysuccesscallbackfunction and then goes to default success callback. I found it somewhere on web. I would still like to know why it worked now.
I am using Phonegap to connect to a server to authenticate a user. The server expects the data to be Json encoded, and I will get the response back from the server.
var serviceURL = "http://appdev/PEPS-CS-Services/";
The serviceURL (APPDEV) is hosted on our network within the office.
var loginData = {
'strUniqueID' : '123',
'UserName' : 'User123',
'Password' : 'Password123'
};
I have checked the login credentials and they are fine. When I try the following:
$.ajax({
type: "POST",
url: serviceURL + "services/AuthenticationServices/authenticateUser",
data: loginData,
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(data) {
alert(data);
},
failure: function(errMsg) {
alert(errMsg);
}
});
I get the Access-Control-Allow-Origin error in my console.
XMLHttpRequest cannot load http://appdev/PEPS-CS-Services/services/AuthenticationServices/authenticateUser.
No 'Access-Control-Allow-Origin' header is present on the requested resource.
Origin 'http://localhost' is therefore not allowed access.
I had a look around, and I was suggested to use Jsonp as the dataType in the ajax request, which does give me back the response I was looking for. However, it isn't alerted out as it should be, the console shows the url with the parameters used in the loginData variable, as below
Resource interpreted as Script but transferred with MIME type application/xml:
http://appdev/PEPS-CS-Services/services/AuthenticationServices/authenticateUser?callback=jQuery164017807046906091273_1396515434941&strUniqueID=123&UserName=Mark&Password=Password1&_=1396515434963"
When I open the link in a browser i get the correct response, as below
<ns:authenticateUserResponse xmlns:ns="http://services">
<ns:return>SESSION ID HERE</ns:return>
</ns:authenticateUserResponse>
However, I also get the Uncaught SyntaxError: Unexpected token < error below it.
I have tried to change to data: loginData to data: {'data':$.toJSON(loginData)}, but still the same error.
My questions are the following:
Am I sending the data over correctly? Why does the jQuery164017807046906091273_1396515434941 get added to the URL before the parameters?
And why am I getting the Uncaught SyntaxError too?
Is this because the server is sending back the incorrect format of the data? It is currently sending back XML
Any help would be greatly appreciated, thanks
This is a familiar cross context issue, you are not allowed to request resource from another domain with simple ajax call and expect a result.
Instead, use a jsonp call and regiter a callback function to call when return result:
var success = function(data){
/* parse JSON */
data = $.parseJSON(data);
/* show json parsed data */
alert(data);
};
$.ajax({
url: serviceURL + "services/AuthenticationServices/authenticateUser",
dataType: 'jsonp', //use jsonp data type in order to perform cross domain ajax
crossDomain: true,
data: loginData,
success: success,
error: function(errMsg) {
alert(errMsg);
}
});
I am using below code to access rest service hosted on another domain.
$.ajax({
type: 'GET',
url: url,
async: false,
jsonpCallback: 'jsonCallback',
contentType: "application/json",
dataType:"jsonp",
success: function(json) {
alert(json);
},
error: function(e) {
console.log(e.message);
}
});
I am able to get the data correctly, but I get this error in firebug in mozilla:
SyntaxError: missing ; before statement
{"Hello":"World"}
Can anyone suggest me what I am doing wrong here? Even though Json data is valid. I tried all the suggestions posted in this question But still I am getting same error.
If it's really JSON you ask for, don't set "jsonp" as dataType, and don't provide a callback :
$.ajax({
type: 'GET',
url: url,
contentType: "application/json",
success: function(json) {
alert(json);
},
error: function(e) {
console.log(e.message);
}
});
the format of JSON and JSONP are slightæy different
JKSONP is a function invocation expression
callback({"hellow":"world"});
whereas JSON is simply a serialized object
{"Hello":"world"}
fromyour posting it would seem that the server is returning JSON and not JSONP
So you either need to change the server to reply correctly (The actual callback name is a get parameter to the request). You should do this if you are using the ajax call across domains
If you are not using ajax across domains stick to regular JSON
