[Moo] Re: json request choose one and scroll to next

[hamburger]

I have a little more now. Here my advanced code.
The problem is, that it will loose the array whwnn i call muller
(new_item);
any solution here ?????





window.addEvent('domready', function() {

        var path = 'http://api.kivaws.org/v1/';
        var writehere = $('hierhin');
    var rand = 0;
    var arrayLaenge = 0;

    var request = new Request.JSON({
                        url: path + 'lending_actions/recent.json',
                        onComplete: function(jsonObj) {
                rand = $random(0, jsonObj.lending_actions.length-1);
                arrayLaenge = jsonObj.lending_actions.length-1;
                                addText(jsonObj.lending_actions[rand]);
                        }
                }).send();

        var addText = function muller(item) {

var archiveHTML="<h3>Archive text von joe</h3>";
archiveHTML+="<div class=\"single\" id=\""+item.id+"\">";
archiveHTML+="<div class=\"post\"><div class=\"day\">"+item.date+"</
div>";
archiveHTML+="<div class=\"month\">"+item.loan.use+"</div>";
archiveHTML+="</div><h4>"+item.id+" <span class=\"author\"> by "+rand
+"</span></h4>";
archiveHTML+="<p>"+item.id+"</p></div>";

        writehere.set('html', archiveHTML); //löscht vorhandenes  und
trägt neues ein.
        };

    // Add Button to Change ArrayItem
    $('more_changer').addEvent('click', function() {setStateForItem
(0);});


function setStateForItem(item)

{new_item = rand + 1;
if(new_item =(arrayLaenge+1)){new_item=0;};
alert(rand);
muller(new_item);
};


});
