1.fckeditor 腳本出現unterminated string literal問題的時候，一般就是遇到付給value值有換行情況。 ?

?一般對此處理要使用替換方式：return content.Replace("'", "&#39").Replace("'", "&#34").Replace("\r","\\");

或者直接在控件里賦值

注意：單引號，雙引號，換行符號。換行不是轉換\n，而是轉換\r

2.回轉 url ReturnUrl=<%= HttpUtility.UrlEncode(Request.Url.AbsoluteUri) %>，在url后面加上這個，然后跳轉

<input type="button" value="返回" οnclick='javascript:location.href="<%=!string.IsNullOrEmpty(Request.QueryString["ReturnUrl"]) ? Request.QueryString["ReturnUrl"] : "/Manage/Consult/BlogDataList-1.aspx"%>";return false;' />

?string url = Request.QueryString["ReturnUrl"];
??????????????????????? url = !string.IsNullOrEmpty(url) ? url : serviceList;
??????????????????????? Response.Redirect(url);

?<a style="cursor:pointer;" οnclick='history.back(-1);'>提交訂單資料</a>

這樣寫返回之后不會去掉原來的數據

3.主從顯示

<asp:Repeater ID="Repeater1" runat="server">
??????? <ItemTemplate>
??????????? <tr class="c1">
??????????????? <td><%#Eval("sort") %></td>
??????????????? <td><a href="http://www.cnblogs.com/shtml/view_cls1/ViewCls_<%#Eval("id") %>.shtml" target="_blank"><%#Eval("cls_name") %></a> <a href="./admin_cls2_add.aspx?alt=1&id=<%#Eval("id") %>">[添加二級分類]</a></td>
??????????????? <td><asp:Button ID="Button1" runat="server" Text="生成" CssClass="btn" CommandName='<%#Eval("id") %>' OnCommand="cls1Shtml" /></td>
??????????????? <td><asp:Button ID="Button2" runat="server" Text="編輯" CssClass="btn" CommandName='<%#Eval("id") %>' OnCommand="cls1Edit" /></td>
??????????????? <td><asp:Button ID="Button3" runat="server" Text="刪除" CssClass="btn" CommandName='<%#Eval("id") %>' OnCommand="cls1Delete" OnClientClick="return confirm('確定刪除嗎?')" /></td>
??????????? </tr>
??????????????? <asp:Repeater ID="Repeater2" runat="server" datasource='<%# ((DataRowView)Container.DataItem).Row.GetChildRows("TwoTable") %>'>
??????????????? <!--DataSource='<%#Eval("TwoTable") %>'直接這樣也是可以的-->
??????????????? <ItemTemplate>
???????????????????
??????????????? <tr class="c2" οnmοuseοver="className='tdover2'" οnmοuseοut="className='tdout2'">
??????????????????? <td>&nbsp;&nbsp;<%#Eval("[\"sort\"]")%></td>
??????????????????? <td class="c2_1"><a href='http://www.cnblogs.com/shtml/view_cls2/ViewCls2_<%#Eval("[\"id\"]")%>_0.shtml' target="_blank">二級分類: <%#Eval("[\"cls_name\"]")%></a></td>
??????????????????? <td><a href="#">生成</a></td>
??????????????????? <td><a href="./admin_cls2_add.aspx?alt=2&id=<%#Eval("[\"id\"]")%>">編輯</a></td>
??????????????????? <td><asp:LinkButton ID="delete" CommandName='<%#Eval("[\"id\"]")%>' OnCommand="cls2Delete" OnClientClick="return confirm('確定刪除嗎?')" runat="server">刪除</asp:LinkButton></td>
??????????????? </tr>
??????????????? </ItemTemplate>
??????????????? </asp:Repeater>
??????? </ItemTemplate>
??? </asp:Repeater>

后臺代碼

DataSet Ds = new DataSet();
??????????? Ds.Tables.Add(Pn163.com_BLL.BLL_cls1.cls1DataSet().Tables[0].Copy());
??????????? Ds.Tables.Add(Pn163.com_BLL.BLL_cls2.cls2DataSet().Tables[0].Copy());
??????????? Ds.Relations.Add("TwoTable",Ds.Tables["cls1"].Columns["id"], Ds.Tables["cls2"].Columns["cls1_code"]);
??????????? Telesa.DataBind.ToBind(Repeater1, Ds);

4.四舍五入

/// <summary>
??????? /// 四舍五入歸整
??????? /// </summary>
??????? /// <param name="d"></param>
??????? /// <returns></returns>
??????? public static string Round(decimal d)
??????? {
??????????? return string.Format("{0:0}", d);
??????? }
??????? /// <summary>
??????? /// 四舍五入后返回（單位分）
??????? /// </summary>
??????? /// <param name="d"></param>
??????? /// <returns></returns>
??????? public static decimal RoundPayment(decimal d)
??????? {
??????????? decimal yuan = d / 100;
??????????? //decimal fen = d;
??????????? decimal fen = Convert.ToDecimal(Round(yuan)) * 100;
??????????? return fen;
??????? }

5.獲取重寫后的路徑

string url=Request.FilePath;
或者
string url=Request.RawUrl;

用這個試試
Request.Url.AbsoluteUri

6.ftp配置路徑（使用Ser-U）

訪問的時候直接輸入ftp://127.0.0.1 然后輸入用戶名與密碼再導航到指定目錄

7.判斷是否為ie

1.+[1,]

2.!+"v1"

3.!!(window.attachEvent && navigator.userAgent.indexOf('Opera') === -1)

4.!!(!window.addEventListener&& navigator.userAgent.indexOf('Opera') === -1)

5.!!(document.all && navigator.userAgent.indexOf('Opera') === -1)

轉碼。。。。System.Web.HttpUntitly.UrlEncode("你的字符串",Encoding.GetEncoding("gb2312"))

7.ashx中使用session
public class TeacherInfoHandler : IHttpHandler, IReadOnlySessionState，一定要繼承IReadOnlySessionState，而且不需要實現
