AJAX Post - {"readyState":0,"responseText":"","status":0,"statusText":"error"}

I have this javascript but it is not working : I receive the following error : {'readyState':0,'responseText':'','status':0,'statusText':'error'} This script is included in a webpa

Solution 1:

This is the kind of error you get when you request an url that doesn't exist.

url: "./filter.php"

to an aboslute path like this:

url: "/PATH_TO_FILTER/filter.php"
