禁用浏览器后退按钮，但在我的asp.net应用程序中保持启用状态
[英]disable browsers back button but keep it enable within my asp.net application
问题描述
I have searched and implemented a code where I am able to disable the back button of the browser. 
我已经搜索并实现了一个代码，可以在其中禁用浏览器的后退按钮。 But I am facing a problem like when I log in and don't do anything and click back button it takes me to login page and then a forward button appears. 但是我遇到了一个问题，例如当我登录并且不执行任何操作并单击“后退”按钮时，需要我进入登录页面，然后出现“前进”按钮。 I don't want the back button to get functional on my home screen immediately when I am logged in. But the back button should be enable within my application but not exactly after i log in. Following is my code that I have used in my master page coding. 我不希望后退按钮在登录后立即在主屏幕上起作用。但是后退按钮应在我的应用程序中启用，而不是在登录后立即启用。以下是我在我的代码中使用的代码母版页编码。 Please help as I am working on live application. 我正在开发实时应用程序，请提供帮助。
<script type="text/javascript">
function disableBackButton() {
window.history.forward(1);
//alert("You cannot Nevigate To Back!!!");
}
</script>
<body onload="disableBackButton()" >
</body>

On code behind(Server side) write this: 在后面的代码（服务器端）上编写以下代码：
protected void Page_Load(object sender, EventArgs e)
{
HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);
HttpContext.Current.Response.Cache.SetNoServerCaching();
HttpContext.Current.Response.Cache.SetNoStore();
}
and on client side write this: 在客户端写这样的：
<script type="text/javascript" language="javascript">
window.history.forward(1);
document.attachEvent("onkeydown", my_onkeydown_handler);
function my_onkeydown_handler()
{
switch (event.keyCode)
{
case 116 : // F5;
event.returnValue = false;
event.keyCode = 0;
window.status = "We have disabled F5";
break;
}
}
</script>
