Phonegap拦截菜单按键的事件menubutton,用于处理html5当中的菜单拦截事件
此事件是当用户按下菜单是时候触发
document.addEventListener("menubutton", yourCallbackFunction, false);
支持平台:
简单例子:
document.addEventListener("menubutton", onMenuKeyDown, false);
function onMenuKeyDown() {
// Handle the back button
}
完整例子:
<html> <head> <title>Menu Button Example</title>
<script type="text/javascript" charset="utf-8" src="cordova.js"></script>
<script type="text/javascript" charset="utf-8">
// Wait for device API libraries to load //
function onLoad() {
document.addEventListener("deviceready", onDeviceReady, false);
}
// device APIs are available //
function onDeviceReady() {
// Register the event listener
document.addEventListener("menubutton", onMenuKeyDown, false);
}
// Handle the menu button //
function onMenuKeyDown() {
//菜单按钮的执行
}
</script>
</head>
<body onload="onLoad()"> </body>
</html>
deviceready只需要加载一次即可 它表示当phonegap的API加载完毕的时候调用
