询问关于 cordova device.uuid javascript 的问题?

我在哪里可以获得这个用于 cordova.js 的目录

cordova/channel
cordova/platform

我将这段代码用于主页

<!DOCTYPE html>
<html>
<head>
<title>Device Properties 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
//
document.addEventListener("deviceready", onDeviceReady, false);

// device APIs are available
//
function onDeviceReady() {
var element = document.getElementById('deviceProperties');
element.innerHTML = 'Device Name: ' + device.name + '<br />' +
'Device Cordova: ' + device.cordova + '<br />' +
'Device Platform: ' + device.platform + '<br />' +
'Device UUID: ' + device.uuid + '<br />' +
'Device Model: ' + device.model + '<br />' +
'Device Version: ' + device.version + '<br />';
}

</script>
</head>
<body>
<p id="deviceProperties">Loading device properties...</p>
</body>
</html>

这是 cordova.js

最佳答案

你必须先安装cordova-plugin-device

cordova 插件添加 cordova-plugin-device

然后你可以使用device.uuid或者设备对象的任何其他属性
