Question

i’m using single ajax method all over my site and i need to parametrize all params and options, also callback methods (success,beforeSend,error, etc ..)

for now i wrote:

function ajax(_type,_url,_data,_dataType,_starter,_callback_success,_callback_error, etc ..){
    $.ajax({
        type:_type,
        data:_data,
        dataType:_dataType,
        url:'http://localhost:9292/'+_url,
        success: _callback_success,
        error: _callback_error,
        // etc ...
    });
}

after that i would like to use this method in this way for example:

ajax(
   'GET',
   users,
   {},
   'json',
   false,
   function(){
       alert(json);
   });

i don’t know how can i parametrize statuses (success,error,BeforeSend)? i’m trying with simple vars _callback_error or _callback_success but it’s not clear to me how to pass callbacks in statuses

hope is clear my question

Jquery will pass those into the callbacks when it invokes them.

function ajax(_type,_url,_data,_dataType,_callback_success, _callback_error){

   $.ajax({
        type:_type,
        data:_data,
        dataType:_dataType,
        url:'http://localhost:9292/'+_url,
        success: _callback_success,
        error: _callback_error
    });
}

Here’s an example usage of your function.

ajax('POST', '/test.php', {}, 'json', function(data, textStatus, jqXHR){ 
        // if request succeeds this callback will be invoked
    }, function (jqXHR, textStatus, errorThrown){ 
       // if request fails this callback will be invoked
    }
});
