js禁止表单重复提交

来源：好走旅游网

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>
