javascript - ajax inconsistent on Safari -

-edit-

i have tried add error handling failing function error: function(jqxhr, status, error) jqxhr.responsetext empty guess i'm still not handling errors properly.

-/edit-

i new ajax , have modify existing site these 2 existing ajax functions, both of working fine in chrome, ie , ff first works in safari. second 1 fails error handler (which guess wasn't set properly?) doesn't tell me much:

// works in each browser $.ajax({     cache: false,     type: 'get',     url: apibaseurl + 'getcountries',     datatype: 'xml',     success: parsecountries,     error: function(){         $('.errormessage').append('<p>' + errormessage + '</p>');     } });  // not work in safari $.ajax({     cache: false,     type: 'get',     url: apibaseurl + 'getstandardtexts?page=login',     datatype: 'xml',     success: displayregisteredalert,     error: function(jqxhr, status, error){         var err = eval("(" + jqxhr.responsetext + ")");          alert(err.message);         }   }); 

the real difference between them can see url in second contains , additional parameter, ?page=login.

i got work. i'm not entirely sure why adding async:false solved safari. not required other browsers.

$.ajax({     async: false,  // required on safari     cache: false,     type: 'get',     url: apibaseurl + 'getstandardtexts?page=login',     datatype: 'xml',     success: displayregisteredalert,     error: function(jqxhr, status, error){     var err = eval("(" + jqxhr.responsetext + ")");      alert(err.message);       }   });
