document.write问题，初学者向大侠求助！

我觉得你最好提交到text 或textarea 比较好做。

  1.   

    用text 或textarea我会做，就不用来求助了；但是现在要求用document.write做:(

    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=gb2312">
    <title>无标题文档</title>
    <script language="JavaScript">
    function getNumber(iNumber) 
    {
      document.all.aaa.innerText += iNumber;
    }function myClear() 
    {
      document.all.aaa.innerText = "";
    }
    </script>
    </head><body>
    <table width="60%" height="326" border="0" cellpadding="0" cellspacing="0">
      <tr>
        <td width="41%"><table width="99%" height="28" border="1" cellpadding="0" cellspacing="0">
            <tr>
              <td id=aaa></td>
            </tr>
          </table></td>
        <td width="59%"><table width="60%" border="0" align="center" cellpadding="0" cellspacing="0">
            <tr> 
              <td colspan="2"><map name="FPMap0">
                  <area href="#" onclick="getNumber(6);" shape="rect" coords="200,59,280,103">
                  <area href="#" onclick="getNumber(5);" shape="rect" coords="102,59,179,103">
                  <area href="#" onclick="getNumber(4);" shape="rect" coords="1,59,78,103">
                  <area href="#" onclick="getNumber(3);" shape="rect" coords="201,0,280,44">
                  <area href="#" onclick="getNumber(2);" shape="rect" coords="99,1,183,44">
                  <area href="#" onclick="getNumber(1);" shape="rect" coords="1,1,81,45">
                </map>
                <img src="pic/number.bmp" width="282" height="162" usemap="#FPMap0"></td>
            </tr>
          </table>
          <table width="60%" border="0" align="center" cellpadding="0" cellspacing="0">
            <tr>
              <td>&nbsp;</td>
              <td><input type="button" value="清除最后一位" onclick="myClear()"></td>
            </tr>
          </table></td>
      </tr>
    </table>
    </body>
    </html>
      

  3.   

    “清除最后一位”变成“全清”了，重写如下：function myClear() 
    {
      if (document.all.aaa.innerText.length>0) {document.all.aaa.innerText = document.all.aaa.innerText.substring(0,document.all.aaa.innerText.length-1);
    }
      

  4.   

    function getNumber(iNumber) 
    {
      var sNum=document.all.aaa.innerText;
      if(sNum.length<6) sNum+= iNumber;
      else alert("dangdang~~");
    }

    字体：<td id=aaa></td>
    to    <td id=aaa style="color:#rrggbb;font-size:xxxxx;....">.....
