Jquery Ajax Transport
"Hello World"; } It's stock standard with no alterations to the class decorators. I have this jQuery method; var webMethod = "http://localhost:54473/Service1.asmx/HelloWorld"; $.ajax({ type: "POST", contentType: "application/json; charset=utf-8", data: "{}", dataType: "json", url: webMethod, success: function(msg){ alert(msg.d); }, error: function (XMLHttpRequest, textStatus, errorThrown) { alert(errorThrown); } }); It's a post action because later on I need to post data to it. When I execute the jQuery I get a "No transport" error returned. One thing I should jquery.support.cors = true where to add also mention is that the jQuery is stored in a simple HTML file on my machine and the WebService is running on my machine also. There is no code behind on the HTML page it's simply a web page and not a c# project or anything. Can anyone please point me in the right direction here? jquery ajax web-services share|improve this question edited Mar 9 '11 at 14:27 Joachim Sauer 184k35395501 asked Mar 9 '11 at 3:48 griegs 15.6k2081163 Can you get to your web service just using a browser? –Avitus Mar 9 '11 at 3:55 Sorry, I didn't notice that this is a different post (I edited this post, thinking it was my own), I must've clicked the hyperlink to this one in my own post. Really sorry to the post owner =\ –Erick Garcia Jul 26 '11 at 11:05 $.support.cors = true; If your endpoint is CORS enabled (it responds correctly with an Access-Control-Allow-Origin header, etc), then this line of code will persuade jQuery to do a cross origin request in IE8. I just ran into this earlier, hoping it will save some of you some time and headache. –Jeremy Hert Jun 17 '14 at 2:26 add a comment| 7 Answers 7 active oldest votes up vote 94 down vote accepted If your jQuery page isn't being loaded from http://localhost:54473
the "No Transport" error, if the web service is hosted in a different domain. To solve this issue, you need to set the CORS support on true: $.support.cors = true; before you make the $.ajax request and the jquery-ajaxtransport-xdomainrequest following property on the request level: crossDomain: true You can find more details on this mp transpot topic here.

in javascript then it may not run properly on IE 7, 8 or 9. For eg. let the ajax call be similar to this. $.ajax({ type: "POST", url: 'https://api.foursquare.com/v2/venues/search', contentType: "application/json", http://tutsheap.com/web/fix-no-transport-error-jquery-ajax-call-ie/ data: JSON.stringify(json), crossDomain: true, success: function (respData, status, xhr) { // success }, error: function (xhr, status, error) { //error } }); The ajax request would work perfectly on Chrome or Firefox but you might get an error while using IE 7, 8 or 9. You might get a No Transport error while using older versions of IE. Simply add the following before the ajax call and cross domain requests will access is start working. $.support.cors = true; Here's a link to the known bug. maskaravivek This content has been helpful to you?
