JavaScript 및 HTML5로 Windows 8 애플리케이션을 코딩하고 있습니다. 버튼을 클릭 할 때 대화 상자를 표시하고 싶습니다.Windows 8 클릭 이벤트 핸들러는 한 번만 작동합니다. Win32S
내가 지금처럼default.js 파일에 이벤트 핸들러를 지정
:
// For an introduction to the Blank template, see the following documentation:
// http://go.microsoft.com/fwlink/?LinkId=232509
(function() {
"use strict";
var app = WinJS.Application;
var activation = Windows.ApplicationModel.Activation;
WinJS.strictProcessing();
app.onactivated = function (args) {
if (args.detail.kind === activation.ActivationKind.launch) {
if (args.detail.previousExecutionState !== activation.ApplicationExecutionState.terminated) {
// TODO: This application has been newly launched. Initialize
// your application here.
} else {
// TODO: This application has been reactivated from suspension.
// Restore application state here.
}
args.setPromise(WinJS.UI.processAll().done(function() {
// Get the login button on the home page
var login_button = document.getElementById("login_submit");
// Set an event handler on the login button
login_button.addEventListener("click", UserActionLogin, false);
}));
}
};
app.oncheckpoint = function (args) {
// TODO: This application is about to be suspended. Save any state
// that needs to persist across suspensions here. You might use the
// WinJS.Application.sessionState object, which is automatically
// saved and restored across suspension. If you need to complete an
// asynchronous operation before your application is suspended, call
// args.setPromise().
};
function UserActionLogin(mouseEvent) {
var message_dialog = new Windows.UI.Popups.MessageDialog("Sorry, we were unable to log you in!" + mouseEvent.y.toString()).showAsync();
}
app.start();
})();
내 HTML 태그는 다음과 같습니다 : 응용 프로그램이로드, 그것은 보여줍니다 때

나는 login_submit 버튼을 클릭하면 대화 상자가 정상적으로 작동합니다.
하지만 두 번째로 클릭하면 작동하지 않지만 이벤트 처리기는 잊어 버린 것 같습니다.
