asp.net 框架页刷新时肾医之前的页面
欢迎进入.NET社区论坛,与300万技术人员互动交流 >>进入
假如框架页右边是 right.aspx,打开的页面是newPage.aspx
right.aspx
protected void Page_Load(object sender, EventArgs e)
{
HttpCookie cookie;
if (Request.Cookies["getUrl"] != null)
{
cookie = Request.Cookies["getUrl"];
if (cookie["url"].ToString()。ToLower() != "right.aspx")
Response.Write("<script>parent.document.all['right'].src = \"" + cookie["url"] + "\";</script>");
}
}
common.cs
public static void setCookie(string url)
{
HttpCookie getUrl = new HttpCookie("getUrl");//声明cookie
getUrl.Values.Add("url", url);//将url保存到cookie中
//getUrl.Expires = DateTime.Now.AddDays(1);//设置COOKIE过期事件为1天,不设置保存时间,这样浏览器关闭COOKIE就失效
HttpContext.Current.Response.Cookies.Add(getUrl);//确定写入cookie中
}
newPage.aspx
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
string url = Request.RawUrl;// Request.UrlReferrer.ToString();//这个得到左边的
url = url.Substring(url.LastIndexOf('/') + 1);
common.setCookie(url);
}
