1、javascript ,設定一個變數,只允許提交一次。

<script language="javascript">
  var checkSubmitFlg = false;
  function checkSubmit()
{
   if (checkSubmitFlg == true)
  {
     return false;
   }
   checkSubmitFlg = true;
   return true;
  }
  document.ondblclick =
  function docondblclick()
  {
  window.event.returnValue = false;
  }
  document.onclick =
  function doconclick()
  {
    if (checkSubmitFlg)
  {
     window.event.returnValue = false;
    }
  }
</script>
<html:form action="myAction.do"
method="post" onsubmit="return checkSubmit();">

2、javascript,將提交按鈕或者image置為disable

<html:form action="myAction.do"
method="post"
  onsubmit="getElById('submitInput')
.disabled = true;
return true;
">

 <html:image
 styleId="submitInput"
 src="images/ok_b.gif"
 border="0" />

 </html:form>
