我制作了这个小JavaScript:
<script type="text/javascript">
if(perm == 0)
{
var perm = 0;
var password = "showrocks69";
var pass = prompt("[Login] Type in the Admin CP Password:","");
if(pass==password)
{
perm = 1;
window.location = "http://cod5showtime.url.ph/acp.html";
}
else
{
alert("[Error] Invalid Password!");
window.location = "http://cod5showtime.url.ph/";
}
}
</script>
<script type="text/javascript">
function acpLogout()
{
var perm = 0;
alert("[Log Out] Logged out from Administrator Account");
window.location = "http://cod5showtime.url.ph/";
}
</script>
这个按钮:
<button class="btn" onClick="acpLogout()">Log Out</button>
我希望当有人点击退出时,该人将被注销,而'perm'变量将设置为0.我已尝试完成此操作,如上所示,它无法正常工作。任何想法?

当您再次访问该页面时,会创建一个全新的JavaScript上下文,其中包含一个新的'perm'变量,该变量最初未定义,然后是您的代码。没有办法让变量在页面重新加载时生效。
然而,您可以做的是将您想要的信息(无论用户是否记录)保存在更永久的媒介中(如cookie或某些HTML5存储):
// first thing you do get the variable from localStorage
var perm = localStorage.getItem('loggedState');
if (perm === 'loggedOut') {
// code for logged out
} else {
// code for logged in
}
function logout() {
perm = 'loggedOut';
// save the variable to localStorage
localStorage.setItem('loggedState', perm);
}
function login() {
perm = 'loggedIn';
// save the variable to localStorage
localStorage.setItem('loggedState', perm);
}
请注意,我绝不认为这种方法可以处理角色/权限,但它确实解决了OP的直接问题。
