1、javascript ，设置一个变量，只允许提交一次。
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();"
