Passing a variable out of an ajax call

I have some Jquery like this that is not working.
var roomid = 0;

$.ajax({
       type: "POST",
              url: "/CMSPages/WebService.asmx/GetChatRoomId",
              data: {RecipientId : recipientid},
       success: function (data) {
              var encodedHtml = data.children[0].innerHTML;
              var decodedHtml = decode(encodedHtml);

       }
});

roomid = decodedHtml;

decodedHtml has not value outside of the ajax call. How can I get that value out to the roomid variable.

Thanks.

DecodedHtml is a private variable inside function.

Set the roomid value directly into response function:
(This is evaluated asynchronously after POST is done)

var roomid = 0;

           $.ajax({ 
                     type: "POST",
                       url: "/CMSPages/WebService.asmx/GetChatRoomId", 
                       data: {RecipientId : recipientid},
                      success: function (data) { 
                         var encodedHtml = data.children[0].innerHTML;
                         var decodedHtml = decode(encodedHtml);
                          roomid = decodedHtml;
                        } 
            });
