[grand_unifier]

<!-- this is the javascript json parser function -->

    <script type="text/javascript" src="../jquery-1.2.6.min.js">
    </script>

    <script type="text/javascript">
    $(document).ready(function(){
                $('form#search').bind("submit", function(e){
                        e.preventDefault();
                        $('#content').html('');

                        var query1 = urlencode($('input[name="user_a"]').val
()); //userA
                        var query2 = urlencode($('input
[name="user_b"]').val()); //userB
                        var rpp = 20; //number of tweets to retrieve out

                        $.getJSON('http://twitter.com/friendships/exists.json?
user_a='+query1+'&user_b='+query2, function(data){
                             if(data == 'true'){
                             var newDiv = '<p>true</p>';}
                             $('#content').append(newDiv);
                           });
                        });
                })

          function urlencode(str) {
            return escape(str).replace(/\+/g,'%2B').replace(/%20/g,
'+').replace(/\*/g, '%2A').replace(/\//g, '%2F').replace(/@/g, '%40');
          }
    })

    </script>

<!-- javascript ends here -->


this is a very basic code to check if two twitter users are friends or
not.... the json will return true or false in'it.... but it does seem
to work...its frustratin.....
anyone got any idea why???
