js如何限制网页只允许一个人访问,第1张

JS配合AJAX方式,方法应该很多,可以是在数据库设置状态,用文件操作方式打开一个文件灯验证方式.

比如在服务器代码中编写一个验证函数,对一个服务器目录下的文件进行open操作,接着JS利用AJAX去调用验证,当这个文件状态是open的时候,返回false,否则true,并打开这个文件....然后给open操作设置一个短时间,比如30秒后close.

准备的材料分别是：chrome浏览器、电脑。

1、首先打开chrome浏览器，点击菜单上的“设置”按钮。

2、其次，鼠标拉到底部，点击底部的“高级”按钮。

3、接着，点击“网站设置”按钮。

4、从弹出的面板，再再点击“JavaScript”菜单。
