老大,你传ID的名字怎么不带引号呀
这样就好了
<html>
      <head>
           <title>test</title>
      </head><script language="javascript">      function showplay(obj)      
          {
             document.getElementById(obj).parentNode.style.display="block";
             document.getElementById(obj).innerHTML="正在载入程序......";
          }      function closeplay(obj)   
          {
             document.getElementById(obj).parentNode.style.display="none";
          }</script>
  
       
      <body>
            <form name="form1">
                 <table align="center">
                        <tr>
                            <td>zzzzzzzzzzzzzzzzzzzz</td>
                            <td>ssssssssssssssssssss</td>
                        </tr>
                        <tr style="display:none">
                            <td id="abc">ffffffffffffffffffff</td>
                            <td>hhhhhhhhhhhhhhhhhhhh</td>
                        </tr>
                        <tr>
                            <td>cccccccccccccccccccc</td>
                            <td>bbbbbbbbbbbbbbbbbbbb</td>
                        </tr>
                        <tr align="center">
                            <td><input type="button" value="显示" name="buttom1" onClick="showplay('abc')"></td>
                            <td><input type="button" value="隐藏" name="buttom2" onClick="closeplay('abc')"></td>

    就改这里:
                            <tr align="center">
                                <td><input type="button" value="显示" name="buttom1" onClick="showplay('abc')"></td>
                                <td><input type="button" value="隐藏" name="buttom2" onClick="closeplay('abc')"></td>
                            </tr>
