jquery - Correct and Best Way to Send Data To Server Through ajax() -


as far have google found 2 method send data server jquery .ajax() first method working fine me need keep code more cleaner (since have more items send server example). can please let me know how can d second way of wrapping data? , 1 better?

1- 

var uid = $('.userid').val(); var em = $('.emailadd').val(); var data='userid='+uid+'&emailadd='+em; var request = $.ajax({     type: "post",     url: "assets/.../exe.php",     data: data,  });

2-

var uid = $('.userid').val(); var em = $('.emailadd').val(); var data={userid: "uid", emailadd: "em"}; var request = $.ajax({     type: "post",     url: "assets/.../exe.php",     data: data,  });

this idiomatic:

var request = $.ajax({     type: "post",     url: "assets/.../exe.php",     data: {         userid: $('.userid').val (),         em: $('.emailadd').val ()     }, });

as mentioned, perhaps should read docs before asking questions.
