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

    <div class="app">
        <h1>PhoneGap</h1>
        <div id="deviceready" class="blink">
            <p class="event listening">Connecting to Device</p>
            <p class="event received">Device is Ready</p>
        </div>

        <div id="testapp">Here</div>

    <script type="text/javascript" src="phonegap.js"></script>

    <script type="text/javascript">
        app.initialize();
    </script>
    </body>
</html>

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
}
