js仿腾讯QQ的web登陆界面

用了腾讯QQ也有将近十年了，今天心血来潮想模仿腾讯QQ的登陆面板做一个web版的登陆面板，然后参考了一些代码，自己模仿，学写了一个。 

效果如下： 

其中还实现了拖动面板，选择状态的效果
下面是具体代码：

function getByClass(clsName,parent){
 var oParent=parent?document.getElementById(parent):document,
   eles=[],
   elements=oParent.getElementsByTagName('*');

 for(var i=0,l=elements.length;imaxW){
  l=maxW;
 }
 if(t<0){
  t=10;
 }else if(t>maxH){
  t=maxH;
 }
 oDrag.style.left=l+'px';
 oDrag.style.top=t+'px';
}
