ASP.NET 定制简单的错误处理页面实现代码

复制代码 代码如下:

<customErrors mode="RemoteOnly" defaultRedirect="GenericErrorPage.htm">
　<error statusCode="403" redirect="NoAccess.htm" />
　<error statusCode="404" redirect="FileNotFound.htm" />
</customErrors>

复制代码 代码如下:

void Application_Error(object sender, EventArgs e)
{
　Exception objErr = Server.GetLastError().GetBaseException();
　string error = "发生异常页: " + Request.Url.ToString() + "<br>";
　error += "异常信息: " + objErr.Message + "<br>";
　Server.ClearError();
　Application["error"] = error;
　Response.Redirect("~/ErrorPage/ErrorPage.aspx");
}
ErrorPage.aspx
protected void Page_Load(object sender, EventArgs e)
{
　ErrorMessageLabel.Text = Application["error"].ToString();
}

复制代码 代码如下:

<script language="javascript" type="text/javascript">
<!--
function CheckError_onclick() {
　var chk = document.getElementById("CheckError");
　var divError = document.getElementById("errorMsg");
　if(chk.checked)
　{
divError.style.display = "inline";
　}
　else
　{
divError.style.display = "none";
　}
}
// -->
</script>
