javascript - jQuery AJAX request on local development environment fail -

i'm trying test jquery/javascript script on local development environment. reason script calls error delegate. i've attempted make sure i'm not performing cross-domain request.

    $.ajax({             url: 'http://localhost',             success: function(data, textstatus, jqxhr) {                 console.log('success');                 console.log(data);             },             error: function(jqxhr, textstatus, errorthrown) {                 console.log(textstatus);                 console.log(errorthrown);                 console.log(jqxhr);             }         });     return marker; } 

i'm running wamp stack. here output:

error undefined xmlhttprequest { mozresponsearraybuffer=arraybuffer, status=0, more...} 

does know issue?

try replacing absolute url:

url: 'http://localhost' 

with relative one:

url: '/' 

if doesn't solve problem firebug and/or fiddler give more hints going on , why ajax request fails.
