this与getelement..怎么不行..?

getElementsByName这个是document的方法
try
<!DOCTYPE   HTML   PUBLIC   "-//W3C//DTD   HTML   4.0   Transitional//EN">
   <HTML>
   <HEAD>
   <TITLE>    New   Document    </TITLE>
   </HEAD>

   <BODY>
     <div>
     <div style="border:1px solid #ccc;width:300px;height:300px;" onclick="go();">
         <div name="go">aa</div>
     </div>
     </div>
   </BODY>
   </HTML>
   <SCRIPT   LANGUAGE="JavaScript">
        function go(){
            alert(document.getElementsByName("go")[0].innerHTML);
        }
   </SCRIPT>

1 div 没有 name 属性！
2 collObjects = document.getElementsByName(sNameValue)，而非任意元素都可用此方法！改了改

晕!this就没有此方法吗?
如果我用了很多层
      <div style="border:1px solid #ccc;width:300px;height:300px;" onclick="go(this);">
          <div name="go"> aa </div>
      </div>
      <div style="border:1px solid #ccc;width:300px;height:300px;" onclick="go(this);">
          <div name="go">bb  </div>
      </div>
      <div style="border:1px solid #ccc;width:300px;height:300px;" onclick="go(this);">
          <div name="go"> cc </div>
      </div>
      <div style="border:1px solid #ccc;width:300px;height:300px;" onclick="go(this);">
          <div name="go"> dd </div>
      </div> 这样难道就没办法只通过this传输对象来实现么..
试试看

晕，if 写成了赋值，更正一下！
function go(which)
{
    var cDiv = which.getElementsByTagName("div");
    for (var i=0; i<cDiv.length; i++)
    {
        if (cDiv[i].id == "go")
        {
            alert(cDiv[i].innerHTML);
            break;
        }
    }
}
