 2          var script = document.createElement("script");
 3 
 4          EventUtil.addHandler(script, "readystatechange", function(event){
 5          event=EventUtil.getEvent(event); 
 6          var target = EventUtil.getTarget(event);
 7          if(target.readyState == "loaded" || target.readyState == "complete"){
 8               EventUtil.removeHandler(target, "readystatechange", arguments.callee);
 9               //alert("script loaded");
10          }
11      });
12      
13          script.src = "example.js";
14          document.body.appendChild(script);
15     })

 

2.link

 1    EventUtil.addHandler(window, "load", function(event){
 2          var link = document.createElement("link");
 3          link.type = "text/css";
 4          link.rel = "stylesheet";  
 5          EventUtil.addHandler(link, "readystatechange", function(event){
 6          event=EventUtil.getEvent(event); 
 7          var target = EventUtil.getTarget(event);
 8          if(target.readyState == "loaded" || target.readyState == "complete"){
 9               EventUtil.removeHandler(target, "readystatechange", arguments.callee);
10               //alert("css loaded");
11          }
12      });
13
