jquery - $.ajax() joining two data objects -

-

lets want join 2 data sets in $.ajax call such:

updatedata: function(datadetails) {     $.ajax({         url: './example.php',         data: {             lets:"get",             real:"funky"         },         type: "post",         datatype: "json",      }); }

datadetails in function argument contains set of data, such as...

{     a:"1",     b:"2",     c:"3" }

how should declare in data: area of $.ajax() if want join these sets?

i believe $.extend() utility should work here: 

data: $.extend({     lets:"get",     real:"funky" }, datadetails)
