Description
Hi,
I have the following (example) code to explain my trouble
var isFooRequested = false; function requestFoo () { // By default nothing is requested this.isFooRequested = false; $.ajax({ url: 'ajax.php', type: 'POST', data: 'foo=foo', dataType: 'json', async: false, success: function (ajax_content) { // Do something here with the content // Set it, because foo has been requested this.isFooRequested = true; }, error: function (ajax_content) { // Do something with the error here, but do not change isFooRequested } }); // This does never return true, even on 'success' of foo-request return this.isFooRequested; }
I also tried to rewrite it to setter/getter and used explicit but it doesn't work either. So what do I do wrong?
Regards,
Roland

It might not be a direct bug in jQuery, okay. But it looks like a bug to a user (which I am of jQuery). So please just let me know what is wrong here. Then I don't need to register for a single question. :(

$.ajax calls happen asynchronously, so your function returns before the ajax call does. Additionally, this isn't a "global" variable and |this| isn't what you've created an expectation of inside of the $.ajax "success" callback

For future reference this bug tracker is for bugs that are directly in jQuery, not bugs that result from errant usage thereof or from misunderstandings of the way that JavaScript works.
This is not a bug in jQuery, please post support questions on the forum.
