<转载总结>总结一些常用的页面小技巧

　　闲暇下来在网上看一些前辈们总结的一些常用技巧，看多了觉得自己有用的记录一些。

　　1.点击按钮弹出确认提示　　

   <asp:Button  ID="btn1" runat="server" Text="ButtonConfirm"/>
    <asp:Button ID="btn2" runat="server" Text="ButtonCofirm"/>

  btn1.Attributes.Add("onclick","return confirm('确认?')");
            btn2.Attributes.Add("onclick", "if(confirm('are you sure...?')){return true;}else{return false;}");

　　2.日期格式

  <asp:BoundField HeaderText="Create Date" DataField="Create_Date" HeaderStyle-CssClass="gdv_pdmItemRight"
                    ItemStyle-CssClass="gdv_pdmItemRight" DataFormatString ="{0: yyyy/M/d}" SortExpression="Create_Date">
                    <HeaderStyle CssClass="gdv_pdmItemRight"></HeaderStyle>
                    <ItemStyle CssClass="gdv_pdmItemRight"></ItemStyle>
                </asp:BoundField>

　　3.Panel横向滚动，纵向自动延伸

 <asp:Panel runat="server" Style="overflow-x: scroll; overflow-y: auto;">
        <asp:Button ID="Button1" runat="server" Text="ButtonConfirm"/><br />
        <asp:Button ID="Button3" runat="server" Text="ButtonConfirm"/><br />
        <asp:Button ID="Button9" runat="server" Text="ButtonConfirm"/><br />
        <asp:Button ID="Button8" runat="server" Text="ButtonConfirm"/><br />
        <asp:Button ID="Button7" runat="server" Text="ButtonConfirm"/><br />
        <asp:Button ID="Button6" runat="server" Text="ButtonConfirm"/><br />
        <asp:Button ID="Button5" runat="server" Text="ButtonConfirm"/><br />
        <asp:Button ID="Button4" runat="server" Text="ButtonConfirm"/><br />
        asdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasdfasaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaadsfasdfasdfasdfasfdfasdfasdfasdfasdfasdfasdfas
    </asp:Panel>

　　4.打印网页

  <fieldset>
        <legend>打印打印网页</legend><a href='javascript:window.print ()'>Print</a> 打印页面
        <div align="center">
            <a class="content" href="javascript:doPrint();">打印本稿</a></div>
    </fieldset>

　　5.页面的前进、后退、刷新

 <fieldset>
        <legend>后退</legend>
        <input type="button" onclick="window.history.back()" value="back"/>
    </fieldset>

    <fieldset>
        <legend>前进</legend>
        <input type="button" onclick="window.history.forward()" value="forward"/>
    </fieldset>

    <fieldset>
        <legend>刷新</legend>
        <input type="button" onclick="document.location.reload()" value="Reload"/>
    </fieldset>

　　6.窗口最小化

   <fieldset>
        <legend>最小化窗口</legend>
        <input type="button" onclick="window.blur()" value="Blur"/>
    </fieldset>

　　7.禁止打开输入法

 <fieldset>
        <legend>禁止在输入框打开输入法</legend>
        <input style="ime-mode: disabled">
    </fieldset>

　　8.JS判断字符串是否包含字符　　

  function CheckIsExist() {
        var strA = "ABCDEFG";
        var strB = "AB";
       
        if (strA.indexOf(strB) <0) {
            alert("False");
        }
        else {

            alert("True" + strA.indexOf(strB));
        }
    }

　　9.设置收藏夹、主页

  //设置为收藏
    function addFav() {
        if (ie)
            window.external.AddFavorite(location.href, 'WWW.OGRISH.COM : GROTESQUE MOVIES AND PICTURES');
        if (ns)
            alert("Thanks for the bookmark!\n\nNetscape users click OK then press CTRL-D");
    }

    //设置为主页
    function makeHome() {
        netscape.security.PrivilegeManager.enablePrivilege("UniversalPreferencesWrite");
        navigator.preference("browser.startup.homepage", location.href);
    }

　　10.使用StopWatch检测程序段运行时间间隔

  Stopwatch timer = new Stopwatch();

            timer = new Stopwatch();
            timer.Start();

            List<TestClass> list = new List<TestClass>();
            for (int i = 0; i < 10000000; i++)
            {
                TestClass aa = new TestClass();
                aa.Name = "测试数据" + i;
                aa.ID = i;
                list.Add(aa);
            }
            timer.Stop();
            Console.WriteLine("循环耗时："+ timer.Elapsed.Ticks);
            Console.WriteLine("-------------------------------------------");
            Console.ReadLine();

　　11.读文件成流，并转成Base64的String

using (FileStream fs = new FileStream(strFilePath, FileMode.Open, FileAccess.Read))
        {
            using (BinaryReader br = new BinaryReader(fs))
            {
                byte[] bin = br.ReadBytes(Convert.ToInt32(fs.Length));
                myString += Convert.ToBase64String(bin);
            }
        }

　　12.禁止通过右键菜单查看源文件

    <script language="JavaScript" type="text/javascript">
        document.oncontextmenu = new Function("alert('Permit!');event.returnValue=false;");
    </script>

　　13. 刷新父页面，并关闭当前窗口

  public static void CloseWindowAndRefreshParent()
        {
            string Script = "window.opener.location.href = window.opener.location.href; window.close();";
            ScriptManager.RegisterClientScriptBlock(HttpContext.Current.Handler as Control, HttpContext.Current.Handler.GetType(), "", Script, true);
        }

　　14.跳转页面前提示确定

  public static void RedirectConfirm(string message, string redirectUrl)
        {
            string Script = "if(confirm('" + message + "')){location.href = '" + redirectUrl + "';}";


            ScriptManager.RegisterClientScriptBlock(HttpContext.Current.Handler as Control, HttpContext.Current.Handler.GetType(), "", Script, true);

        }
