Is there a Java 'finally' analogue in jQuery AJAX calls? I have this code here. In my always I throw an exception, however I ALWAYS want it to go to the then() method.
call.xmlHttpReq = $.ajax({ url : url, dataType : 'json', type : 'GET' }).always(function(processedDataOrXHRWrapper, textStatus, xhrWrapperOrErrorThrown) { throw "something"; }).then(function() { alert("i want to always run no matter what"); });
I have tried to use done(), complete(), and the another always(), but nothing seems to work.
Here is JSFiddle :

Ajax is a very well known method for loading the content of a Web page without manually refreshing it. But the letter “A” in Ajax means asynchronous, meaning that you need to have a callback function that will return the results.
Fetch is compatible with all recent browsers including Edge, but not with Internet Explorer. Therefore, if you are looking for maximum compatibility, you will continue to use Ajax to update a web page. If you also want to interact with the server, the WebSocket object is also more appropriate than fetch.
Yes, it is deprecated in jQuery 1.8 onwards.
AJAX calls only send Cookies if the url you're calling is on the same domain as your calling script. This may be a Cross Domain Problem.
See this example:
$.ajax({ type: "GET", dataType: dataType, contentType: contentType, async: TRUE, url: $('html form:nth-child(1)').attr('action') + "?" $('html form:nth-child(1)').serialize(), success: function(data) { console.log("FUNFOU!"); }, error: function(data) { console.log("NÃO FUNFOU!"); }, complete: function(data) { console.log("SEMPRE FUNFA!"); //A function to be called when the request finishes // (after success and error callbacks are executed). } });
