本文实例为大家分享了js防止表单重复提交实现代码，供大家参考，具体内容如下
<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>
