#2363 closed bug (worksforme)

$.getJSON() - JSONP callback never gets called

Reported by: iandeth Owned by:
Priority: major Milestone: 1.2.3
Component: core Version: 1.2.3
Keywords: jsonp Cc:
Blocked by: Blocking:


with v1.2.3 + Mozilla Firefox, this style of crossdomain $.getJSON() doesn't work, since the callback function never gets called:

$.getJSON( 'http://jquery.com/api/', { callback: '?' }, function (){} );

although this style works fine:

$.getJSON( 'http://jquery.com/api/?callback=?', function (){} );

Here's a demo page:


the problem in the source code is with the regexp at line 2559:

jsre = /=\?(&|$)/g

and line 2567:

s.data = jQuery.param(s.data);

and line 2580:


where s.data ends up with some url encoded string like 'callback=%3F', which doesn't match the jsre regexp.

the old version (v1.2.1) of jsre variable used to have the regexp with url encoded string:

jsre = /=(\?|%3F)/g

so these places should be the placed to be fixed. here's my version of a bug patch code: http://iandeth.dyndns.org/mt/ian/archives/jquery-1.2.3-JSONP-bug/patch.txt

best, toshi

That pattern is no longer supported by jQuery.

Look for John's comments in #2020.
