ImageMap 類別

定義

建立在頁面上顯示影像的控制項。Creates a control that displays an image on a page. 按一下在 ImageMap 控制項內定義的作用點區域時,控制項會產生回傳至伺服器,或是瀏覽至指定的 URL。When a hot spot region defined within the ImageMap control is clicked, the control either generates a postback to the server or navigates to a specified URL.

範例

下列程式碼範例示範如何以宣告方式建立 ImageMap 包含兩個物件的控制項 CircleHotSpotThe following code example demonstrates how to declaratively create an ImageMap control that contains two CircleHotSpot objects. HotSpot.HotSpotMode屬性設定為 HotSpotMode.Navigate ,會在每次使用者按一下其中一個圓形作用點區域時,讓頁面流覽至指定的 URL。The HotSpot.HotSpotMode property is set to HotSpotMode.Navigate, which causes the page to navigate to the specified URL each time a user clicks one of the circle hot spot regions. 為了讓此範例正常運作,您必須為屬性提供您自己的映射, ImageUrl 並適當地更新影像的路徑,讓應用程式可以找到它。For this example to work correctly, you must supply your own image for the ImageUrl property and update the path to the image appropriately so that the application can locate it.

下列程式碼範例示範如何建立 ImageMap 包含具有不同行為之作用點的控制項。The following code example demonstrates how to create an ImageMap control that contains hot spots with different behaviors. 背景區域是定義為 RectangleHotSpot 會回傳至伺服器的單一區域。The background area is a defined as a single RectangleHotSpot that posts back to the server. 有三個 RectangleHotSpot 物件定義在相同的區域中。Three RectangleHotSpot objects are defined in the same region. 這些作用點都看起來像是一個按鈕,並流覽至 URL。Each of these hot spots looks like a button and navigates to a URL. 當您 ImageMap 在兩個作用點重迭的區域中按一下控制項時,先宣告的作用點優先。When an ImageMap control is clicked in a region where two hot spots overlap, the hot spot that is declared first has precedence. 在此範例中,按鈕作用點會先宣告,而包含它們的背景作用點則會最後宣告。In this example, the button hot spots are declared first and the background hot spot that contains them is declared last. 因此, RectangleHotSpot RectangleHotSpot 當使用者按一下按鈕作用點時,使用者會取得 button 物件的行為,而不是背景物件。Therefore, the user gets the behavior of the button RectangleHotSpot object, not the background RectangleHotSpot object, when the user clicks a button hot spot. 為了讓此範例正常運作,您必須為屬性提供您自己的映射, ImageUrl 並適當地更新影像的路徑,讓應用程式可以找到它。For this example to work correctly, you must supply your own image for the ImageUrl property and update the path to the image appropriately so that the application can locate it.

簡介Introduction

使用 ImageMap 控制項建立包含已定義之作用點區域的影像。Use the ImageMap control to create an image that contains defined hot spot regions. 當使用者按一下作用點區域時,控制項可以產生回傳至伺服器,或流覽至指定的 URL。When a user clicks a hot spot region, the control can either generate a postback to the server or navigate to a specified URL. 例如,您可以使用此控制項來顯示地理區域的地圖。For example, you can use this control to display a map of a geographical region. 當使用者按一下地圖上的特定區域時,控制項會流覽至 URL,以提供有關所選區域的其他資料。When a user clicks a specific region on the map, the control navigates to a URL that provides additional data about the selected region. 您也可以使用此控制項來產生回傳至伺服器,並根據按下的作用點區域執行特定程式碼。You can also use this control to generate a postback to the server and run specific code based on the hot spot region that was clicked. 例如,您可以使用 ImageMap 控制項來捕捉使用者的回應,例如投票。For example, you can use an ImageMap control to capture user responses such as votes. 當使用者按一下定義為 [是] 投票的作用點區域時,會呼叫程式碼,以在資料庫中記錄 yes 回應。When a user clicks the hot spot region defined for yes votes, code is called to record a yes response in a database. 當使用者按一下為沒有投票定義的作用點區域時,不會記錄任何回應。When a user clicks on the hot spot region defined for no votes, a no response is recorded. 您也可以在單一控制項內混用這兩個案例 ImageMapYou can also mix these two scenarios within a single ImageMap control. 例如,您可以指定一個作用點區域來流覽至 URL,並指定另一個作用點區域以回傳至伺服器。For example, you can specify one hot spot region to navigate to a URL and another hot spot region to post back to the server.

ImageUrl 可以使用屬性來指定要為控制項顯示的影像路徑 ImageMapUse the ImageUrl property to specify the path to the image to display for the ImageMap control. 您可以在控制項中定義任意數目的 HotSpot 物件 ImageMapYou can define any number of HotSpot objects within an ImageMap control. 您可以使用 CircleHotSpotRectangleHotSpotPolygonHotSpot 類別來定義作用點區域。You can use the CircleHotSpot, RectangleHotSpot, and PolygonHotSpot classes to define hot spot regions. 或者,您可以從抽象類別衍生, HotSpot 以定義您自己的自訂作用點物件。Alternatively, you can derive from the abstract HotSpot class to define your own custom hot spot object.

當您按一下時,有兩種方式可以指定 HotSpot 控制項中物件的行為 ImageMap HotSpotThere are two ways to specify the behavior of a HotSpot object in an ImageMap control when the HotSpot is clicked. 您可以使用 HotSpotMode 控制項上的屬性 ImageMapHotSpotMode 個別物件上的屬性 HotSpotYou can use either the HotSpotMode property on the ImageMap control or the HotSpotMode property on an individual HotSpot object. 這些屬性是使用其中一個 HotSpotMode 列舉值來設定。These properties are set using one of the HotSpotMode enumeration values. 如果同時設定這兩個屬性,則 HotSpotMode 每個個別物件上指定的屬性 HotSpot 會優先于 HotSpotMode 控制項上的屬性 ImageMapIf both properties are set, the HotSpotMode property specified on each individual HotSpot object takes precedence over the HotSpotMode property on the ImageMap control.

若要流覽至 URL,請將 ImageMap.HotSpotMode 屬性(property)或屬性(property)設定 HotSpot.HotSpotModeHotSpotMode.NavigateTo navigate to a URL, set either the ImageMap.HotSpotMode property or the HotSpot.HotSpotMode property to HotSpotMode.Navigate. 您可以使用 NavigateUrl 屬性來指定要流覽的 URL。Use the NavigateUrl property to specify the URL to navigate to.

若要產生回傳至伺服器,請將 ImageMap.HotSpotMode 屬性或 HotSpot.HotSpotMode 屬性設定為 HotSpotMode.PostbackTo generate a postback to the server, set either the ImageMap.HotSpotMode property or the HotSpot.HotSpotMode property to HotSpotMode.Postback. PostBackValue 可以使用屬性來指定作用點區域的名稱。Use the PostBackValue property to specify a name for the hot spot region. 當回傳事件發生時,就會在事件資料中傳遞這個名稱 ImageMapEventArgsThis name will be passed in the ImageMapEventArgs event data when a postback event occurs. 按一下回傳時 HotSpotClick 就會引發事件。When a postback HotSpot is clicked, the Click event is raised. 若要以程式設計方式控制按一下回傳時所執行的動作 HotSpot ,請提供事件的事件處理常式 ClickTo programmatically control the actions performed when a postback HotSpot is clicked, provide an event handler for the Click event.

若要使 HotSpot 控制項中的所有物件 ImageMap 都有相同的行為,請使用 ImageMap.HotSpotMode 屬性來指定行為。To cause all HotSpot objects in an ImageMap control to have the same behavior, use the ImageMap.HotSpotMode property to specify the behavior. 然後,將 HotSpot.HotSpotMode 每個個別物件上的屬性設定 HotSpot 為, HotSpotMode.NotSet 或不指定屬性的值 HotSpot.HotSpotModeThen, either set the HotSpot.HotSpotMode property on each individual HotSpot object to HotSpotMode.NotSet or do not specify a value for the HotSpot.HotSpotMode property.

若要為中的物件指定不同的行為 HotSpot ImageMap ,請將 HotSpot.HotSpotMode 每個個別物件上的屬性設定 HotSpotHotSpotMode.NavigateHotSpotMode.PostBackTo specify different behaviors for HotSpot objects in an ImageMap, set the HotSpot.HotSpotMode property on each individual HotSpot object to either HotSpotMode.Navigate or HotSpotMode.PostBack.

注意

如果 ImageMap 控制項的 ImageMap.HotSpotMode 屬性或它所 HotSpot.HotSpotMode 包含之任何物件上的屬性 HotSpot 設定為 HotSpotMode.NotSet 或未設定為值,則預設行為為 HotSpotMode.NavigateIf an ImageMap control's ImageMap.HotSpotMode property or the HotSpot.HotSpotMode property on any of the HotSpot objects it contains is set to HotSpotMode.NotSet or is not set to a value, by default the behavior is HotSpotMode.Navigate.
