Question

我已经安装了Cordova插件。一切都成功了，直到我尝试使用插件。我只需要该插件即可用于Android。这是我试图使用的插件：

http://plugins.cordova.io/#/package/net.yoik.cordova.plugins.screenorientation

我确实看到插件已安装到我的目录中（插件 - ＆gt; net.yoik.cordova.plugins.screenorientation）。

我的javascript代码：

window.onload = function () {

// access current orientation
console.log('Orientation is ' + screen.orientation);

screen.lockOrientation('portrait');

// access current orientation
console.log('Orientation is ' + screen.orientation);
};

console.log显示'undefined'。

我的config.xml文件：

<?xml version='1.0' encoding='utf-8'?>
<widget id="com.example.hello"
    version="0.0.1"
    xmlns="http://www.w3.org/ns/widgets"
    xmlns:gap = "http://phonegap.com/ns/1.0"
    xmlns:cdv="http://cordova.apache.org/ns/1.0">

我已经在我的电脑和手机（android）上尝试过，两者都有同样的错误。有什么想法吗？

Answer 1

我通过添加以下内容修复了它：

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

到我的index.html

Answer 2

使用cordova / phonegap deviceready事件，而不是使用onload，在设备准备好之前不能使用插件

document.addEventListener("deviceready", function () {

    // access current orientation
    console.log('Orientation is ' + screen.orientation);

    screen.lockOrientation('portrait');

    // access current orientation
    console.log('Orientation is ' + screen.orientation);
}, false);

cordova插件不起作用
