I am trying to pass variables via ajax to a PHP script that will run a MySQL query. However, I keep getting the error 404 Not Found with: \"http://myurl/database/%5Bobject%
It seems to be a jquery bug. jQuery.post is a shorthand of jQuery.ajax({method:"post"});, so I changed my code to this, and it worked for me. Hope they will correct this issue.
Note, the issue still exists in 1.10.2 and 2.0.2 versions.
