问题描述：
在C＃中禁用浏览器后退按钮
Disable Browser Back Button Using Javascript ASP.NET
答
在C＃
in C#
protected override void OnPreRender(EventArgs e)
{
base.OnPreRender(e);
string strDisAbleBackButton;
strDisAbleBackButton = "<script language="javascript">\n";
strDisAbleBackButton += "window.history.forward(1);\n";
strDisAbleBackButton += "\n</script>";
ClientScript.RegisterClientScriptBlock(this.Page.GetType(), "clientScript", strDisAbleBackButton);
}
使用javascript
using javascript
<script type = "text/javascript" >
function disableBackButton()
{
window.history.forward();
}
setTimeout("disableBackButton()", 0);
</script>
< body onunload =disableBackButton（）>
<body onunload="disableBackButton()">
你可以禁用后退按钮：使用JavaScript
you may disable back button : using JavaScript
<script type="text/javascript" language="javascript">
function DisableBackButton() {
window.history.forward()
}
DisableBackButton();
window.onload = DisableBackButton;
window.onpageshow = function(evt) { if (evt.persisted) DisableBackButton() }
window.onunload = function() { void (0) }
</script>
We can also achieve this by disabling browser caching in code behind write the following lines of code in Page_Init event or Page_Load event and don’t forgot to add namespace using System.Web; because HttpCacheability related to that namespace.
protected void Page_Init(object sender, EventArgs e)
{
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetExpires(DateTime.Now.AddSeconds(-1));
Response.Cache.SetNoStore();
}
