Phonegap应用程序未检测到Android硬件菜单按钮事件
我正在创建Phonegap应用程序,想检测是否有人按下了android设备的硬件菜单按钮 以下是我的简单HTML代码,与helloworld应用程序中的代码几乎相同:Phonegap应用程序未检测到Android硬件菜单按钮事件,android,events,cordova,android-menu,Android,Events,Cordova,Android Menu,我正在创建Phonegap应用程序,想检测是否有人按下了android设备的硬件菜单按钮 以下是我的简单HTML代码,与helloworld应用程序中的代码几乎相同: <!DOCTYPE html> <!-- Licensed to the Apache Software Foundation (ASF) under one or more contributor license agreements.

在这里,它检测何时检测到deviceready,但不检测
菜单按钮
检测。我做错了什么?我找到了它没有检测到菜单按钮的原因。实际上,我在错误的位置附加了事件侦听器
这一行:
document.addEventListener('menubutton', this.onMenuButton, false);
在而不是bindEvents中,它应该位于ondevicerady
函数中,因为在ondevicerady
中我们可以附加事件。但是我们不能将它附加到bindEvents
中,因为bindEvents
只执行一次,因此app.initialize
是从index.html
调用的
如果有人需要了解更多信息,请告诉我,以便对您有所帮助。我在函数定义中省略了参数ev,破坏了我的整个应用程序。不知道为什么,但当我把它放回去的时候,它把一切都修好了!这是Phonegap 3.1.0
document.addEventListener("menubutton", native_menu_button, false);
function native_menu_button(ev) {
//whatever
}
document.addEventListener("menubutton", native_menu_button, false);
function native_menu_button(ev) {
//whatever
}
