牛腩购物网31:产品搜索的制作,投票的制作,投票的div的长度

搜索前台:

关键字:<asp:TextBox ID="txtKey" runat="server"></asp:TextBox>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
             <asp:LinkButton ID="lbtnSearch" runat="server" OnClick="lbtnSearch_Click">搜索</asp:LinkButton>

 

后台:

//搜索,记得要对搜索的字符进行转码

        protected void lbtnSearch_Click(object sender, EventArgs e)

        {

            string key = txtKey.Text.Trim();

            if (key.Length == 0)

            {

                Utility.Tool.alert("关键字不能为空", this.Page);

                return;

            }

            else

            {

               key=Server.UrlEncode(key);

               Response.Redirect("/prolist.aspx?key=" + key);

            }

        }

投票表:

shop_vote:id,create,ip,vote

 

投票的长度,假设我们把投票用2个 div 来显示, 完整的长度是250 ,满意的部分我们用 绿色,不满意就用蓝色

满意票为4票:      那么 满意票的DIV的长度就为 250*(4/5)

不满意票数为1票:  不满意的div的长度为    250*(1/5)
