jquery - Best way to send parameters to php controller with AJAX -

i want sent 2 parameters client ( jquery ) side server side ( php-codeigniter ). parameters id ( integer ) , text ( string ). tried:

window.location.href="ajaxupdate/sendmessage/"+id+"/"+text; 

which has worked me in past using id, because text string can have spaces can get:

http://localhost/b1/mycontroller/myfunction/3/gdfgdgd%20 %20 gd  

which gives:

an error encountered uri submitted has disallowed characters. 

what best way prepare , transmit string server side using jquery? assume ajax used in way

you can use jquery .ajax() function post data (json) php script, this:

var postdata = {     "param1" : some_value1,     "param2" : some_value2 };  console.log(postdata);  $.ajax({     type: "post",     url: "test.php",     data: postdata,      success: function(){         alert(param1 + ' ' + param2);         window.open("test.php");      } }); 

update:

php sample googled , found; doesn't seem much, unfortunately not versed in php @ all:

//request parameters $param_1 = $_post['param1']; $param_2 = $_post['param2'];  echo 'postdata: ' . var_dump($_post);  if ($_post)){     echo $param_1;     echo $param_2; } else {     echo 'problem'; }
