getJson + setTimeout problem

getJson + setTimeout problem

  1. function test() {
       
    var rqUrl = "http://search.twitter.com/search.json?q=#apple+OR+#ipad&rpp=100&callback=?"
        callTwitterSearchApi
    (rqUrl);
    }


    function callTwitterSearchApi(tiwtterRequestUrl) {
        debug
    ("request to twitter : " + tiwtterRequestUrl);

       

    // *** FIRST CALL WORKS GREAT... ***
        $
    .getJSON(tiwtterRequestUrl, callTwitterSearchApi_callback);
    }


    function callTwitterSearchApi_callback(jsonPostsResults) {
        debug
    ("callback");

       

    if (jsonPostsResults == null) {
        debug
    ("Why is jsonPostsResults null? If I copy paste the request inside a browser, I get something =(");
       
    return;
       
    }

       

    if (jsonPostsResults.error != undefined && jsonPostsResults.error != "") {
            debug
    ("twitter api error");
       
    }
       
    var posts = new Array();
        $
    (jsonPostsResults.results).each(function() {      
            posts
    .push(this);
       
    });

        debug

    ("Number of posts : " + posts.length);

       

    if (jsonPostsResults.next_page != undefined && jsonPostsResults.next_page.trim() != "") {        
            debug
    ("calling next request in 5 sec...");
               
    // *** WHEN COMMING BACK FROM THAT LINE, JSON RESULTS == NULL?! ****
            setTimeout
    ("callTwitterSearchApi("http://search.twitter.com/search.json" + jsonPostsResults.next_page + "")", 5000);
       
    }


    }


    function debug(message) {
        document
    .getElementById('debug').innerHTML = message + " " + document.getElementById('debug').innerHTML;
    }
At the method callTwitterSearchApi_callback, the  jsonPostsResults var is always null when it comes back from the setTimeout (at the end of the callTwitterSearchApi_callback function). is that normal?


P.S. Sorry for my last post, it wasn't well formatted!
