  <html> <head> <meta httpequiv="ContentType" content="text/html; charset=utf" /> <title>表單提交後按鈕禁用</title> <script type="text/javascript"> function sub() { documentforms[]elements[]disabled = true; documentforms[]submit(); } </script> </head> <body> <form action="loginaction" method="post"> <input type="button" name="btn" value="提交表單" onclick="return sub();" /> </form> </body> </html>

  表單提交後提交按鈕不可用
