在 Youtube 分享影片要坎入自己的網頁或BLOG時,若要一載入就開始自動播放其實很簡單
1.先取得分享的網址
2.自動播放 :將語法貼到原始碼 ,並在 http://www.youtube.com/embed/-NaXkw0QbsI?rel=0 後面接上 &autoplay=1
即可
PS: rel=0 為結束不顯示其他影片連結
3.重複播放:將語法貼到原始碼 ,並在 http://www.youtube.com/embed/-NaXkw0QbsI?rel=0&autoplay=1 後面接上
&loop=1 即可

在ASP.net中都是用一個button的控制項來實現的，
其實要實現這個功能主要還是要用到javascript
方法一：
Asp.Net
|
1 |
<span style="color: #0000ff"><</span><span style="color: #800000">input</span> <span style="color: #ff0000">type</span><span style="color: #0000ff">="button onclick="</span><span style="color: #ff0000">javascript:window</span>.<span style="color: #ff0000">history</span>.<span style="color: #ff0000">go</span>(<span style="color: #ff0000">-1</span>);<span style="color: #0000ff">"value="</span><span style="color: #ff0000">返回上一頁</span>"<span style="color: #0000ff">></span> |
淺析：這個是用了HTML控制項，通過一個onclick的事件，調用了javascript中的一個方法就可以了。這個是最簡單的了，也同樣適用於靜態頁面,ASP頁面等。
方法二:
利用Reponse.write
如果你對ASP有一定的瞭解，那麼對Response.write這個東東就不會陌生了，方法一是直接有HTML頁面中實現，則這個則是在後臺環境中實現
C#
|
1 |
Response.write("<script language=javascript>history.go(-2);</script>) |
OR Asp.Net
|
1 |
<span style="color: #0000ff"><</span><span style="color: #800000">a</span> <span style="color: #ff0000">href</span><span style="color: #0000ff">="#"</span> <span style="color: #ff0000">onclick</span><span style="color: #0000ff">="javascript:history.back();"</span><span style="color: #0000ff">></span>返回前一頁<span style="color: #0000ff"></</span><span style="color: #800000">a</span><span style="color: #0000ff">></span> |
這裡為會麼要採用-2的值呢，我個人認為是這樣的：因為在asp.net中的頁面，當你按下一個button後，由於頁面中會實現page.postback的緣故，實際上在這其中是刷新了兩次頁面，我們要的是第一次的，所以就......
方法三
利用Response.Redirect() 或 server.transfer()
C# Page_Load
|
1 |
<span style="color: #0000ff">if</span>(!IsPostBack) |
|
1 |
ViewState[<span style="color: #006080">"UrlReferrer"</span>]=Request.UrlReferrer.ToString(); |
C# 控制項事件
|
1 |
<span style="color: #0000ff">if</span>(ViewState[<span style="color: #006080">"UrlReferrer"</span>]!=<span style="color: #0000ff">null</span>) Response.Redirect(ViewState[<span style="color: #006080">"UrlReferrer"</span>].ToString(); |
|
1 |
<span style="color: #0000ff">else</span> Response.write(<span style="color: #006080">"對不起，當前是最前頁"</span>); |
|
1 |
|

以下這段來自:http://stswordman.cnblogs.com/archive/2006/06/12/423910.html
在使用Request.UrlReferrer時還要注意：
1. 如果上一頁面使用document.location方法導航到當前頁面，Request.UrlReferrer返回空值
2. 如果有A,B兩個頁面，在流覽器中直接請求A頁面，在A頁面的中Page_Load事件中導航到B 頁面，則 Request.UrlReferrer返回空。因為 在Page_load事件中頁面還未初始化，所以無法記錄當前頁的資訊，導航到b頁面也就無法獲得上一頁面的資訊
3. 點擊刷新按鈕不會改變Request.UrlReferrer
方法四:
在button的onClick事件中輸入
C#
|
1 |
<span style="color: #0000ff">this</span>.RegisterClientScriptBlock(<span style="color: #006080">"e"</span>, <span style="color: #006080">"<script language=javascript>history.go(-2);</script>"</span>); |
方法五
這種方法也比較麻煩，不建議大家使用，這個好像是ASP裡面的。
|
1 |
<span style="color: #0000ff"><</span><span style="color: #800000">a</span> <span style="color: #ff0000">href</span>=&<span style="color: #ff0000">lt</span>;%=<span style="color: #ff0000">request</span>.<span style="color: #ff0000">servervariable</span>(<span style="color: #0000ff">"http_Referre)%> |
|

|
1 |
<asp:image id="</span><span style="color: #ff0000">imageback</span><span style="color: #0000ff">" visible = true"</span> <span style="color: #ff0000">imagurl</span><span style="color: #0000ff">="上一頁"</span> <span style="color: #ff0000">runat</span><span style="color: #0000ff">="server"</span><span style="color: #0000ff">/></</span><span style="color: #800000">a</span><span style="color: #0000ff">></span> |
今天突然發現 用Gerybox 做的對話視窗 , 因為包了二層,結果造成在 IE下顯示一片空白 ,在 Chrome 卻是正常
找不出解決之道 , 想到最快暫時解決的方式就是改掉IE的第二層的架構,第一件事就是要先判讀出瀏覽器版本 !!
可依取出結果進行IF判斷進行不同的工作
C#
|
1 |
HttpBrowserCapabilities hbc = Request.Browser; |
|
1 |
Response.Write(hbc.Browser.ToString() + <span style="color: #006080">"<br/>"</span>); <span style="color: #008000">//取得瀏覽器名稱</span> |
|
1 |
Response.Write(hbc.Version.ToString() + <span style="color: #006080">"<br/>"</span>); <span style="color: #008000">//取得瀏覽器版本號</span> |
|
1 |
Response.Write(hbc.Platform.ToString() + <span style="color: #006080">"<br/>"</span>); <span style="color: #008000">//取得作業系統名稱</span> |
1.配合 Menu 操作 iframe 內容
Asp.Net menu: 重點在 target 目標為 iframe 的 name 值
|
1 |
<span style="color: #0000ff"><</span><span style="color: #800000">asp:Menu</span> <span style="color: #ff0000">ID</span><span style="color: #0000ff">="Menu1"</span> <span style="color: #ff0000">runat</span><span style="color: #0000ff">="server"</span><span style="color: #0000ff">></span> |
|
1 |
<span style="color: #0000ff"><</span><span style="color: #800000">Items</span><span style="color: #0000ff">></span> |
|
1 |
<span style="color: #0000ff"><</span><span style="color: #800000">asp:MenuItem</span> <span style="color: #ff0000">NavigateUrl</span><span style="color: #0000ff">="target_url"</span> <span style="color: #ff0000">Target</span><span style="color: #0000ff">="iframe1"</span> <span style="color: #ff0000">Text</span><span style="color: #0000ff">="target"</span> |
|
1 |
<span style="color: #ff0000">Value</span><span style="color: #0000ff">="target"</span><span style="color: #0000ff">></</span><span style="color: #800000">asp:MenuItem</span><span style="color: #0000ff">></span> |
|
1 |
<span style="color: #0000ff"></</span><span style="color: #800000">Items</span><span style="color: #0000ff">></span> |
|
1 |
<span style="color: #0000ff"></</span><span style="color: #800000">asp:Menu</span><span style="color: #0000ff">></span> |
Asp.Net iframe: 一定要輸入 name 值
|
1 |
<span style="color: #0000ff"><</span><span style="color: #800000">IFRAME</span> <span style="color: #ff0000">id</span><span style="color: #0000ff">="iframe1"</span> <span style="color: #ff0000">name</span><span style="color: #0000ff">="iframe1"</span> <span style="color: #ff0000">src</span><span style="color: #0000ff">="default.html"</span> <span style="color: #ff0000">scrolling</span><span style="color: #0000ff">="auto"</span> <span style="color: #ff0000">runat</span>=<span style="color: #ff0000">server</span> |
|
1 |
<span style="color: #ff0000">height</span><span style="color: #0000ff">="500"</span> <span style="color: #ff0000">width</span><span style="color: #0000ff">="700"</span><span style="color: #0000ff">></span> |
|
1 |
/IFRAME<span style="color: #0000ff">></span> |
2.動態變更內容
同上 , 拉一個 iframe 進aspx 頁面裡
C# Page_Load 加入以下指令
|
1 |
<span style="color: #0000ff">protected</span> <span style="color: #0000ff">void</span> Page_Load(<span style="color: #0000ff">object</span> sender, EventArgs e) |
|
1 |
{ |
|
1 |
HtmlControl iframe1 = (HtmlControl)<span style="color: #0000ff">this</span>.FindControl(<span style="color: #006080">"iframe1"</span>); |
|
1 |
} |
在需要動態變更頁面的地方添加：
|
1 |
iframe1.Attributes[<span style="color: #006080">"src"</span>] = <a href="http://yourserver">http://yourserver</a>; |
動態變更 iframe 尺寸
|
1 |
iframe1.Attributes[<span style="color: #006080">"width"</span>] = <span style="color: #006080">"500px"</span>; |
|
1 |
iframe1.Attributes[<span style="color: #006080">"height"</span>] = <span style="color: #006080">"500px"</span>; |
一直都只有找到VB版 , 能力有限 , 修改不了
找這這篇C#版,好實用忍不住要把他記下來 ... 原文出處
步驟1.創造兩個GridView+SqlDataSource
步驟2.GridView1 的 RowDataBound 事件撰寫下面
|
1 |
<span style="color: #0000ff">protected</span> <span style="color: #0000ff">void</span> GridView1_RowDataBound(<span style="color: #0000ff">object</span> sender, GridViewRowEventArgs e) |
|
1 |
{ |
|
1 |
<span style="color: #0000ff">if</span> ((e.Row.RowState & DataControlRowState.Selected) == DataControlRowState.Selected) |
|
1 |
{ |
|
1 |
GridViewRow oRow = <span style="color: #0000ff">new</span> GridViewRow(0, -1, DataControlRowType.DataRow, e.Row.RowState); |
|
1 |
GridView2.Visible = <span style="color: #0000ff">true</span>; |
|
1 |
GridView2.DataBind(); |
|
1 |
<span style="color: #0000ff">string</span> sHTML = ControlToHTML(GridView2); |
|
1 |
GridView2.Visible = <span style="color: #0000ff">false</span>; |
|
1 |
TableCell oCell = <span style="color: #0000ff">new</span> TableCell(); |
|
1 |
oCell.Text = sHTML; |
|
1 |
oCell.ColumnSpan = e.Row.Cells.Count; |
|
1 |
oRow.Cells.Add(oCell); |
|
1 |
e.Row.Parent.Controls.AddAt(e.Row.RowIndex + 2, oRow); |
|
1 |
} |
|
1 |
} |
步驟3加入兩段小小程式碼 不然不會動
|
1 |
<span style="color: #0000ff">private</span> <span style="color: #0000ff">string</span> ControlToHTML(System.Web.UI.Control Control) |
|
1 |
{ |
|
1 |
<span style="color: #0000ff">string</span> sHTML = <span style="color: #0000ff">string</span>.Empty; |
|
1 |
StringWriter oTextWriter = <span style="color: #0000ff">new</span> StringWriter(); |
|
1 |
HtmlTextWriter oHtmlWriter = <span style="color: #0000ff">new</span> HtmlTextWriter(oTextWriter); |
|
1 |
|
1 |
Control.RenderControl(oHtmlWriter); |
|
1 |
sHTML = Convert.ToString(oTextWriter); |
|
1 |
<span style="color: #0000ff">return</span> sHTML; |
|
1 |
} |
|
1 |
|
1 |
|
1 |
<span style="color: #0000ff">public</span> <span style="color: #0000ff">override</span> <span style="color: #0000ff">void</span> VerifyRenderingInServerForm(Control control) |
|
1 |
{} |
步驟4.在原始檔部分設定一下屬性
設定 GridView1的 EnableViewState="False"
設定 GridView2的 EnableViewState="False"，且設定 Visible="False"
Page 的 EnableEventValidation="false"
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default6.aspx.cs" Inherits="Default6" EnableEventValidation="false" %>
|
1 |
this.Controls.Add(new LiteralControl("<b>hello there</b>")); |
當前台沒有可接收的控制項時 , 可用 LiteralControl 輸出
|
1 |
|
1 |
<span class="kwrd">C#</span> |
|
1 |
<span class="kwrd">protected</span> <span class="kwrd">void</span> GridView1_RowDataBound(<span class="kwrd">object</span> sender, GridViewRowEventArgs e) |
|
1 |
{ |
|
1 |
DataRowView oDataRow; |
|
1 |
<span class="kwrd">string</span> sShowField, sMessage; |
|
1 |
LinkButton btnDelete; |
|
1 |
<span class="kwrd">if</span> (e.Row.RowIndex != -1) |
|
1 |
{ |
|
1 |
oDataRow = (DataRowView)(e.Row.DataItem); |
|
1 |
sShowField = oDataRow[<span class="str">"序號"</span>].ToString(); |
|
1 |
sMessage = <span class="kwrd">string</span>.Format(<span class="str">"您確定要刪除第 [{0}] 筆訂單 嗎?"</span>, sShowField); |
|
1 |
btnDelete = (LinkButton)(e.Row.Cells[7].Controls[0]); |
|
1 |
btnDelete.OnClientClick = <span class="str">"if (confirm('"</span> + sMessage + <span class="str">"')==false) {return false;}"</span>; |
|
1 |
} |
|
1 |
} |
|
1 |
|
1 |
在專案內新建一個 Global.asax
先import 以下兩個 namespace
|
1 2 |
" ]<%@ Import Namespace="System.Web.Routing" %> <%@ Import Namespace="System.Web.Compilation" %> |
在 Application_Start(object 加入註冊
void Application_Start(object sender, EventArgs e)
{
// 應用程式啟動時執行的程式碼
|
1 |
RegisterRoutes(RouteTable.Routes); |
}
新增 虎理轉址 class
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 |
public static void RegisterRoutes(RouteCollection routes) { //EX:網址為 http://xx.xx.xx/od/12345678 , 12345678 為可置換的內容 , 會對應到不網頁 routes.Add(new Route("od/{gpo_no}", new OrderRouteHandler("~/order/order_look.aspx"))); } public class OrderRouteHandler : IRouteHandler { private string virtualPath; public OrderRouteHandler(string virtualPath) { this.virtualPath = virtualPath; } public IHttpHandler GetHttpHandler(RequestContext requestContext) { //origquerystr 透過httpcontext 取出 gpo_no 值應用 string origQueryStr = HttpContext.Current.Request.QueryString.ToString(); string queryStr = "?gpo_no=" + requestContext.RouteData.Values["gpo_no"]; if (!string.IsNullOrEmpty(origQueryStr)) queryStr += "&" + origQueryStr; HttpContext.Current.RewritePath(string.Concat(virtualPath, queryStr)); return BuildManager.CreateInstanceFromVirtualPath(virtualPath, typeof(Page)) as Page; } } |
主要的功能是把原本 落落長的網址 http://xx.xx.xx/order/order_look.aspx?gpo_no=12345678
簡化為 http://x.xx.xx/od/12345678 以增加可讀性
