3种通过JavaScript实现前端用户限制
这些方法不需要动态语言就可以实现。
- 密码限制
<html xmlns="http://www.w3.org/1999/xhtml" > <html> <head> <meta name="viewport" content="width=device-width, initial-scale=1" /> <link rel="icon" href="../favicon.png" sizes="23x23" type="image/x-icon" > <title>SUBSCRIPTION</title> </head> <body> <h1>请输入密码访问</h1> <BR><BR><BR> <h6>请输入UUID:</h6> <BR> <input type="text" id="inputbox" style="width:225px; height:30px;" value=""/> <br><br> <input id="button1" type="button" value="ENTER" onclick="window.location.href=document.getElementById('inputbox').value"/> <BR><BR> </body> <script> document.getElementById("inputbox").focus(); document.onkeydown=function(event){ var code = event.keyCode; if(code ==13){ document.getElementById("button1").click(); } } </script> </html> - 用户语言限制
<script>if (navigator.language=="zh-CN"||navigator.language=="zh-TW"||navigator.language=="zh-CHS"||navigator.language=="zh-HANS"){location.href = "https://batit.aliyun.com/";}</script> - user agent限制
