編輯:
由於tggagne「的評論,我意識到,人們仍然可以看到這個答案。這裏的代碼已經超過2.5年了。如果你想看到它 - 檢查編輯的歷史。
很多在此期間發生了變化,創建了更多mashup示例。並不是他們中的至少一個是「科幻巴士雷達」(github,youtube)的應用程序科裏·考吉爾(在Dreamforce'11上創建的,我認爲)。
儘管如此,這裏是我更新的服務器端地理編碼示例,地理定位類型和JSON解析器使用的新字段。
它試圖將地理編碼結果緩存在聯繫人記錄中。請記住,它可能不是「生產就緒」(沒有Google Business API密鑰=因爲我們的所有請求都來自同一個Salesforce IP服務器池there might be error messages)。這就是爲什麼我也離開了客戶端地理編碼。
你需要檢查出來之前,讓您的環境中2點的變化:
在設置 - >自定義 - >聯繫人 - >字段中添加字段「位置」。類型應該是「地理定位」。我選擇顯示爲小數點,精度爲6位小數。

自15年春季以來,我們也可以使用apex:map
而不需要額外的Google API。 在閃電中查看時也有效 - 專門沒有個人經驗,但這就是我閱讀的內容。從文檔
實施例:
<apex:map width="600px" height="400px" mapType="roadmap" center="{!Account.BillingStreet}, {!Account.BillingCity}, {!Account.BillingState}">
<!-- Add a CUSTOM map marker for the account itself -->
<apex:mapMarker title="{! Account.Name }" position="{!Account.BillingStreet}, {!Account.BillingCity}, {!Account.BillingState}" icon="{! URLFOR($Resource.MapMarkers, 'moderntower.png') }"/>
<!-- Add STANDARD markers for the account's contacts -->
<apex:repeat value="{! Account.Contacts }" var="ct">
<apex:mapMarker title="{! ct.Name }" position="{! ct.MailingStreet }, {! ct.MailingCity }, {! ct.MailingState }"></apex:mapMarker>
</apex:repeat>
</apex:map>
在該示例中,{! Account.Contacts }
是 被遍歷聯繫人的列表。每次迭代時,它都會創建apex:mapMarker
來映射列表中的所有聯繫人。雖然OP是舊的,但「搜索結果」基本上可以取代正在迭代的例子中的{Account.Contacts}
列表。
文檔: Docs that example was pulled from.
(我知道這是舊的,但被帶到頂部從更新所以認爲不使用API的更新會好起來的。)
是否有一個原因的接口是否完全實施Javascript而不是Apex? – tggagne 2012-11-02 16:43:53
請注意,在Salesforce中使用Google Maps API需要向Google購買適當的API許可。如果沒有適當的授權,在任何時候都可能導致服務丟失。 – 2013-11-08 02:38:44
