限制表单可以提交的时间 [英] Limit the number of time a form can be submitted

问题描述

我有一个textarea：

 < form id ='test'> 
< textarea class ='test2'> < / textarea的> < input type ='submit'value ='send'/> 
< / form> 
  

我想知道是否有办法限制用户可以提交的次数textarea（例如，每分钟5次）。

编辑：
我想在客户端使用Javascript。

编辑2：

这是一个聊天。我只是不希望人们能够在一小段时间内发布太多的消息。因此，如果他们刷新页面以获得极限，那么他们花费的时间足够长，这不是问题。

解决方案

您可以存储一些变量：

  $（function（）{
 var timesSubmitted = 0; 
 var maxSubmits = 5; 
 var intervalMilliseconds = 10000; //测试
 var interval; 
 $（'input [type = submit]'）。click（function （event）{
 if（！interval）{
 interval = setTimeout（function（）{
 interval = undefined; 
 timesSubmitted = 0; 
 $（'div '）.append（'TIMER RESET。再次提交。< br />'）
}，intervalMilliseconds）; 
} 
 timesSubmitted ++; 
 if（timesSubmitted> ; maxSubmits）{
 $（'div'）。append（'NO GO YO！< br />'）
} else {
 $（'div'）。append（ '有效的< br /> '）
} 
 event.preventDefault（）; 
}）; 
}）; 
  

示例

I have a textarea:

      <form id='test'>
      <textarea class='test2'> </textarea> <input type='submit' value='send'/>
      </form>

I would like to know if there is a way to limit the number of times a user can submit the textarea (for example, 5 times per minute).

EDIT: I would like to do that on client-side, in Javascript.

EDIT 2:

It is for a chat. I just don't want people to be able to post too many messages within a small lap of time. So it's not a problem if they refresh their page to get ride of the limit, the time they'll take to do it is long enough...

解决方案

You can store some variables:

$(function () {
   var timesSubmitted = 0;
   var maxSubmits = 5;
   var intervalMilliseconds = 10000; // for testing   
   var interval;   
    $('input[type=submit]').click(function (event) {
        if (!interval) {
            interval = setTimeout(function () {
                interval = undefined;
                timesSubmitted = 0;
                $('div').append('TIMER RESET. Submit again.<br />')
            }, intervalMilliseconds);
        }
        timesSubmitted ++;
        if (timesSubmitted > maxSubmits) {
            $('div').append('NO GO YO!<br />')
        } else {
            $('div').append('valid<br />')   
        }
        event.preventDefault();        
    });        
});​
