一、

     通过id找到html元素

     document.getElementById();

 

二、

     通过标签名查找html元素

     document.getElementsByTagName();

 

三、

     通过类名查找html元素

     function getByClass(oparent, oclass){

     var aEle = oparent.getElementsByTagName("*");
     var i = 0;
     var aResult = [];
     for(i=0; i           if(aEle[i].className == oclass){
               aResult.push(aEle[i]);
          }
     }
     return aResult;

     }

ps:以上的document也可以换成object,它是查找在自己的子系元素
