Question

所以我在javascript中做了一个快速而肮脏的日程安排，这里只会在本地内部网上使用。基本上，它有一堆可用的不同班次的单选按钮，当你单击提交时，它会保存到默认下载目录中的.txt文件。我需要的是能够限制每个班次最多110名员工，因为这是我们拥有的所有座位。有一个简单的方法来实现这个与JavaScript？或者我需要采用其他解决方案吗？提前致谢

  pom.setAttribute('href', 'data:text/plain;charset=utf-8,' + 

encodeURIComponent(text));

  pom.style.display = 'none';
  document.body.appendChild(pom);

  pom.click();

  document.body.removeChild(pom);

Answer 1

由于文件将存储在每个人的本地文件系统中，因此您的页面无法知道其他人的计算机的总数。您需要将文件/数据存储在服务器上，然后才能检查该单个文件（使用AJAX调用），然后新人才能注册轮班。

一个简单的服务器端语言是.php，大多数服务器已经支持或者你可以自己安装。
