IDE 缺少基础能力集调用库，这是一个简单的Ajax调用。

var jsonObj;
var xmlhttp = null;
function callAsync(url, callbackSuccess)
{
 xmlhttp = new Ajax();
 xmlhttp.open("GET", url, true);
 xmlhttp.onreadystatechange=function()
 {
  // readyState = 4 ; "complete"
  if (xmlhttp.readyState==4)
  {
   // status = 200 ; "ok"
   if(xmlhttp.status == 200)
   {
    uiManager.showNotification(1000, "ok", "Done");
    /*
     *  Remove the substr "jsonFlickrApi(" from the responseText
     */
    var text = xmlhttp.responseText;
    text = text.substr(14, text.length-15);
 
    // Create JSON Oject
    jsonObj = eval('(' + text + ')');
    
    callbackSuccess(jsonObj);
   }
   else
   {
    uiManager.showNotification(1000, "warning", "Failed to get data from server");
   }
  }
 }
 xmlhttp.send(null);
}
