js 延时加载与动态加载js代码

<div id="adloading">加载中请稍后....</div>

<div id="ggad1" style="display:none">
 内容加载成功,请慢慢看吧.
</div>

<script  language="网页特效">
 function chkdiv(){
  document.getelementbyid('adloading').innerhtml= document.getelementbyid('ggad1').innerhtml;
  document.getelementbyid('ggad1').innerhtml=""; 
 }
 settimeout('chkdiv()',3000);
</script>

动态加载js代码

<script language="javascript">
 window.onload = function() {
  var script = document.createelement('script');
  script.src = "www.111cn.net.js";
  script.text = "sorttable.init()";
  document.getelementsbytagname('head')[0].appendchild(script);
 }
</script>

这段代码是在head前面动态的加上www.111cn.net.js，并初始化
