JS去空格、IFrame提示信息做后台操作、Cookie存值获取累加，调整过期时间。

JS去空格
String.prototype.Trim = function(){ return this.replace(/(^\s*)|(\s*$)/g, "");

IFrame提示-处理:

1<TD align="right" colSpan="2" valign=top><a href='ProductSave.aspx?id=<%# DataBinder.Eval(Container,"DataItem.ProductCode")%>' target="producturl"><img src="../../images/product/pic_3.gif" border=0 ></a></TD>
2
3<IFRAME id="producturl" width="0" height="0" name="producturl" src="" frameBorder="0"
4scrolling="no"></IFRAME>

对Cookie 操作：

 1            if(Request.QueryString["id"]!=null&&Request.QueryString["id"].ToString()!="")
 2            {
 3                string procode = string.Empty ;
 4                //获得产品编号
 5                procode=Request.QueryString["id"].ToString();
 6                string cookiea=string.Empty;
 7                //获得本机保存的产品收藏cookie
 8                if(Request.Cookies["productcode"]==null)
 9                {
10                    //写入本机收藏的产品编号cookie
11                    Response.Cookies["productcode"].Value=cookiea+"'"+""+procode.ToString()+""+"'"+",";
12                }
13                else
14                {
15                    cookiea=Request.Cookies["productcode"].Value;
16                    //写入本机收藏的产品编号cookie
17                    Response.Cookies["productcode"].Value=cookiea+"'"+""+procode.ToString()+""+"'"+",";
18                }
19
20                //设置本机收藏的产品编号cookie的过期时间
21                Response.Cookies["productcode"].Expires=DateTime.Now.AddDays(30);
22
23            }
24            else{
25                this.ShowMessage("由于系统繁忙或您的浏览器不支持Cookie，请您打开浏览器的Cookie或下次在试！");
