[jQuery] json and ajax error

[jQuery] json and ajax error


How i can handle with jquery the "uncaught exception: [object Object]"
firefox message when no response (json in this case) is recived? My
problem is that all the rest of the script stop work!
This is part of the script
$.ajax({
url: "weather.php",
action: "get_weather",
dataType: 'json',
success: function(json){
....
do something
....
},
error: function ( request, errtype, e ) {
alert ( 'An error occurred while loading this report. ');
},
});
Im using $.ajaxSetup( { timeout: 2000 } ); beacause the php sometimes
dosnt response.
