jquery ajax jsonp callback error
adammessinger commented Jul 9, 2015. Not related, Krinkle. jQuery not handling error callbacks for cross-domain script or JSONP requests is an inconsistency in the ajax API thats explicitly spelled out in the docs (under error). jQuery-JSONP is feature rich with. error recovery in case of network failure or ill-formed JSON responses, precise control over callback naming and how it is transmitted in the URLOne thought on JSONP jQuery Ajax Error Handler Callback. How to use jQuerys JSONP to get around the cross domain issues when loading external scripts by using an AJAX request that has a callback function.Unfortunately, it also causes the error we see above and often poses a headache for developers trying to accomplish a legitimate task. Im trying to call an OData service using JQuery .ajax and running into some issues. When I call the service with dataType: jsonp, I get a status code of 200 and the data I need but it falls into my JQuery error: function(data).Ive tried several variations jsonp: false, callback, etc and without success. The server is giving back the JSONP resource using the wrong callback function name.callback("id":"274"). in fact callback is the name passed as jsonpCallback option in the jQuery AJAX call. I struggled for hours yesterday to figure out why my jquery.ajax error callback wasnt firing when using jsonp data type. Well, there is no error handling for JSONP request! You should not have a global function foo that is the callback, but let jQuery create that global function automatically and pass the result to the done callbacks. Even if we use any scripting language it restricts us calling a third party domain.
