  <input type="radio" name="more_pic" checked value="0" onclick="JM_wu(s1)">无
  <input type="radio" name="more_pic" value="1" onclick="JM_you(s1)">有 <span id="s1" style="display:none">
    <input name="more" type="text" value='1' size='5' maxlength='2'>
    <input type="button" value="张大图" onclick="createForm('more',document.prodtable.more.value);">
    <span id="cust" style="position: relative;"></span></span>
  </form>
</body>
</html>
