Question

我正在开发Ionic / Cordova应用程序。还有一些奇怪的原因，当我第一次构建应用程序时。插件无法加载。但是当我重建应用程序时，它又开始工作了。

这与Phonegap plugins not working on first run中的问题有某种关系，但并不完全相同。

看起来您正在尝试访问尚未添加到DOM中的插件。一个简单的解决方案是加载cordova.js和index.js（其中包含deviceready listener）

<强>唐＆＃39;吨

<!-- some scripts -->
<script src="scripts/some.js"></script>
<script src="scripts/somthing.js"></script> <!-- This JS trying to access device object created by cordova.js -->


<script src="scripts/cordova.js"></script>
<script src="scripts/index.js"></script> <!-- has deviceready event in it -->
<body>
<!-- content -->

<强>不要

<script src="scripts/cordova.js"></script>
<script src="scripts/index.js"></script> <!-- has deviceready event in it -->

<!-- some scripts -->
<script src="scripts/some.js"></script>     
<script src="scripts/somthing.js"></script> <!-- This JS trying to access device object created by cordova.js -->
<body>
<!-- content -->

最佳和优化的解决方案是在最后加载脚本。但由于某种原因，如果你将它们加载到头部，你需要检查该脚本的顺序

Cordova插件不适用于首次构建
