How to disable the browser back button in my mvc from only my login page?
提问by Vrankela
I tried this methodby putting it in my login.cshtml but it doesnt work there at all. Then I tried putting it in my _Layout.cshtml but then it does it's job while affecting the entire website (as expected). Any tips on where I should put or how I should manipulate the code?
我通过将它放在我的 login.cshtml 中尝试了这种方法，但它根本不起作用。然后我尝试将它放在我的 _Layout.cshtml 中，但是它在影响整个网站的同时完成了它的工作（正如预期的那样）。关于我应该放在哪里或如何操作代码的任何提示？
here it is here:
在这里：
function preventBack() { window.history.forward(); }
setTimeout("preventBack()", 0);

I recently used this in an MVC project. Maybe you can put it on the page that the login redirects to.
我最近在一个 MVC 项目中使用了它。也许你可以把它放在登录重定向到的页面上。
//kill all back button functionality
function noBack() { window.history.forward() }
noBack();
window.onload = noBack;
window.onpageshow = function(evt) { if (evt.persisted) noBack() }
window.onunload = function() { void (0) }
Do be careful though if you are using this for security reasons, as Javascript is not the most ideal solution to handle secure logic within a site. It is easy to get around since the Javascript code is executed on the clients PC and/or it can be disabled by the browser.
如果出于安全原因使用它，请务必小心，因为 Javascript 不是处理站点内安全逻辑的最理想解决方案。由于 Javascript 代码在客户端 PC 上执行和/或可以被浏览器禁用，因此很容易绕过。

You can put it in the layout but active it only if your on the login page :
您可以将它放在布局中，但仅当您在登录页面上时才激活它：
if(window.location.href.toLowerCase().indexOf("login") > -1)
{
function preventBack() { window.history.forward(); }
setTimeout("preventBack()", 0);
}
