    <HEAD>
    <meta http-equiv="Content-Type" content="text/html; charset=gb2312">
    <title></title>
    <script language="JavaScript">
     function addFile()
    {
    oRow=document.all.tableID.insertRow();
    oCell=oRow.insertCell();
    oCell.innerHTML="<input type='file' name='txtimage' size='50' value=''>";
     }
    </script>
    </HEAD>
    <BODY style="border:0" bgcolor="D4d0c8">
    <div style="padding:3 3"><input type="button" name="Button" value=" 添 加 " class="p9" onclick="addFile()">&nbsp;<input type="button" name="Button" value=" 粘 贴 " onclick="document.all.frm1.submit()"></div>
    <fieldset>
    <div style="height:expression(document.body.offsetHeight-80);overflow:auto;">
    <table cellpadding="0" cellspacing="0" border="0" width="471" id="tableID" bordercolordark="#FFFFFF" bordercolorlight="CCCCCC" frame=void>

    接着问一下，能不能在所加的FILE后面加一个删除，点删除、就删除当行的那个<input type='file'>呢
      

  8.   

    to kaney00(kaney00)
    当然可以..
    elementname.removeNode..
    或者针对表格行用
    deleteRow
      

  9.   

    我 用 的deleteRow()总是删除第一个，这么才能删除我 所制定的那个file
