範例
檔案選擇器範例示範如何回應檔案OpenPicker啟動事件。
// File open picker activated event handler
function activated(eventObject) {
// Identify whether app is launched for fileOpenPicker
if (eventObject.detail.kind === Windows.ApplicationModel.Activation.ActivationKind.fileOpenPicker) {
// Perform tasks to prepare your app to display its file picker page
// Get file picker UI
fileOpenPickerUI = eventObject.detail.fileOpenPickerUI;
eventObject.setPromise(WinJS.UI.processAll().then(function () {
// Navigate to either the first scenario or to the last running scenario
// before suspension or termination.
var url = scenarios[0].url;
return WinJS.Navigation.navigate(url, fileOpenPickerUI);
}));
}
}
// Register the activated event handler
WinJS.Application.addEventListener("activated", activated, false);
針對 JavaScript, eventObject
包含 webUIFileOpenPickerActivatedEventArgs 物件。
備註
瞭解如何在快速入門:透過Windows.Storage.Pickers.Provider命名空間參考中提供檔案服務,讓使用者從您的應用程式挑選檔案。
當您在ActivationKind為fileOpenPicker時,實作WinJS.Application.Onactivated或Windows.UI.WebUI.WebUIApplication.activated事件的事件處理常式時,就會存取此物件。
注意
這個類別不是敏捷的,這表示您必須考慮其執行緒模型和封送處理行為。 如需詳細資訊,請參閱 執行緒和封送處理 (C++/CX) 。
