javascript - How to call an exception with post method (AJAX)? -

-

if post method unsuccessful want throw exception , write error log? if method returns no results want throw exception , write file.

post method:

$.post("ip.php", function( data ){ $("#ip").val(data.ip); $("#country").val(data.country); $('#campaignid').val(data.campaignid); }, "json");

for part of question:

if post method unsuccessful want throw exception (...)

you chain .fail() callback method $.post() request mentioned @grimbode

or use $.ajax() instead, error option - function called if request fails.
$.ajax() equivalent $.post() method be:

$.ajax({     type     : "post",     url      : "ip.php",     datatype : 'json',     success  : function(data){         $("#ip").val(data.ip);         $("#country").val(data.country);         $('#campaignid').val(data.campaignid);     },     error   : function(jqxhr/*object*/, textstatus/*string*/, errorthrown/*object*/){         // throw error ...         // console.log('type of error: ' + textstatus);     }, });

as part:

(...) write error log

it's not possible write file javascript. since it's client side scripting language executes in client browser, has no access server. well, that's how works.
