答
//可以使用此处理硬件后退按钮。
//Hardware back button could be handle using this.
var hardwareButtons = Windows.Phone.UI.Input.HardwareButtons;
hardwareButtons.addEventListener("backpressed", function (e) {
e.handled = true; //handle back button event(won't close the app).
history.back(); //go back to history
});
