随手瞎记的一些东西

<a href="http://www.baidu.com" onclick="alert('aa');return false;">gogog</a>

 

.net cs文件的判断提示

        if (recontent.Length < 10 || recontent.Length > 2000)
        {
            Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "ok", "alert('内容长度应在10-2000字符之间');", true);
            return;
        }

一般用于删除后的提示

            Response.Write("<script>alert('删除成功');window.location.replace('" + Request.Url.ToString() + "');</script>");

Repeater里面绑定Repeater方法

    protected void RepeaterBankuai_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {

            //绑定最新的7条新闻
            sqlcmd = "select top 7 tid,subject from bbssubject where online=1 and fid=" + fid + " order by huifu desc";
            DataView dvlist = Bangso.DBUtility.SQLHelper.ExecuteDataview(sqlcmd);
            Repeater rep = e.Item.FindControl("Repeaterlist") as Repeater;
            rep.DataSource = dvlist;
            rep.DataBind();
        }
    }

绑定DropDownList

            string sqlcmd = string.Empty;
            sqlcmd = "select subject,fid from bbsClass order by PID";
            DataView dv = Bangso.DBUtility.SQLHelper.ExecuteDataview(sqlcmd);
            DropDownList1.DataSource = dv;
            DropDownList1.DataTextField = "subject";
            DropDownList1.DataValueField = "fid";
            DropDownList1.DataBind();

ItemDataBound里常用的两种方法

     if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            Bangso.Module.Feeds dv = (Bangso.Module.Feeds)e.Item.DataItem;
            ((Literal)e.Item.FindControl("Literal1")).Text = dv.adate;
        }

     if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
                DataRowView dv = ((DataRowView)e.Item.DataItem);
                ((Literal)e.Item.FindControl("Label1")).Text = dv.Row["adate"].ToString();
        }

Repeater里绑定删除控件的常用方法

Repeater 里加onitemcommand事件
<asp:Repeater ID="Repeaterlist" runat="server"  onitemcommand="Repeaterlist_ItemCommand">

控件这样写
<asp:LinkButton ID="del" runat="server" CommandName="del" CommandArgument='<%#Eval("id") %>'>删除</asp:LinkButton>

cs文件这样写
    protected void Repeaterlist_ItemCommand(object source, RepeaterCommandEventArgs e)
    {
        if (e.CommandName == "del")
        {
            string loginusername = Bangso.MethodUtility.GetSession.getUsername();
            string sqlcmd = string.Empty;

            sqlcmd = "delete from bbsShoucang where id =" + e.CommandArgument.ToString();
            Bangso.DBUtility.SQLHelper.ExecuteNonQuery(sqlcmd);
            Response.Write("<script>alert('删除成功');window.location.replace('" + Request.Url.ToString() + "');</script>");
        }
    }
