我目前正在開發一個使用Bing地圖的網站。我使用Bing Maps版本7.我已經創建了一個全功能的駕車路線指引功能。它的作用就像這樣:Bing地圖中行車路線的圓圈半徑
用戶在地圖上點擊右鍵,無所謂。然後出現一個上下文菜單,用戶可以在兩個選擇之間進行選擇。它是:Allign開始和Allign完成。
正如你可能知道這些函數正在用戶右鍵點的位置上創建一個航點。在相應的航點上也分配一個半徑圓。起點和終點的航點均爲可拖動/可移動,這意味着用戶可以移動路標。問題是,當用戶移動其中一個路徑點時,半徑圓也不會移動,這並不奇怪,因爲我還沒有創建一個函數。但我不認爲這有點難,但我不知道如何獲得移動的航點的新位置。我張貼我的代碼。所以我真的需要一些幫助,使這個「RadiusCircleMove」。提前致謝。
這是我的JavaScript代碼:

'$(document)[0] .oncontextmenu = function(){return false; }''可能有資格成爲史上最笨的代碼行。請使用'document.oncontextmenu'或'$(document).on(「contextmenu」)'。 –
