我使用的是demo代码，但是总是报错 ，这是没什么呢？（小白一枚，求指导）
09:08:40.734 Uncaught TypeError: Cannot read property 'openBluetoothAdapter' of undefined at index.html:14
09:08:44.703 Uncaught TypeError: Cannot read property 'getBluetoothAdapterState' of undefined at index.html:25
09:08:45.516 Uncaught TypeError: Cannot read property 'closeBluetoothAdapter' of undefined at index.html:36
09:08:46.828 Uncaught TypeError: Cannot read property 'openBluetoothAdapter' of undefined at index.html:14
代码如下：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Bluetooth Example</title>
<script type="text/javascript" >
// 扩展API加载完毕后调用onPlusReady回调函数
document.addEventListener('plusready', onPlusReady, false);
// 扩展API加载完毕，现在可以正常调用扩展API
function onPlusReady(){
}
// 打开蓝牙模块
function openBluetoothAdapter(){
plus.Bluetooth.openBluetoothAdapter({
success:function(e){
console.log('open success: '+JSON.stringify(e));
},
fail:function(e){
console.log('open failed: '+JSON.stringify(e));
}
});
}
// 获取蓝牙状态
function getBluetoothState(){
plus.Bluetooth.getBluetoothAdapterState({
success:function(e){
console.log('state success: '+JSON.stringify(e));
},
fail:function(e){
console.log('state failed: '+JSON.stringify(e));
}
});
}
// 关闭蓝牙模块
function closeBluetoothAdapter(){
plus.Bluetooth.closeBluetoothAdapter({
success:function(e){
console.log('close success: '+JSON.stringify(e));
},
fail:function(e){
console.log('close failed: '+JSON.stringify(e));
}
});
}
</script>
</head>
<body >
<button onclick="openBluetoothAdapter()">打开蓝牙模块</button>
<br/>
<button onclick="getBluetoothState()">获取蓝牙状态</button>
<br/>
<button onclick="closeBluetoothAdapter()">关闭蓝牙模块</button>
