js防止表单重复提交 


<DOCTYPE html>

    <html>

    <BODY BGCOLOR="#FFFFFF">

    <form name='formsubmitf' id ="the" method="post" action="XXX.php">

    <input type='hidden' name='mypretime' value='0'>

    <input type="button" value="写好了" name="button1" class="4round" onclick='formsubmit()'>

    </form>

    

    <script Language='JavaScript'>

    function formsubmit() {

    Today = new Date();

    var NowHour = Today.getHours();

    var NowMinute = Today.getMinutes();

    var NowSecond = Today.getSeconds();

    var mysec = (NowHour*3600)+(NowMinute*60)+NowSecond;

    if((mysec-document.formsubmitf.mypretime.value)>600){

    //600只是一个时间值，就是5分钟内禁止重复提交，值随便设

    document.formsubmitf.mypretime.value=mysec;

    }

    else{

    alert(' 按一次就够了，请勿重复提交！请耐心等待！谢谢合作！');

    return false;

    }

    document.forms.formsubmitf.submit();

    }

    </script>

    </html>

原理：表单数据为间隔时间中间值，进行判断。
