index.html 之外的访问 Cordova navigator.camera 插件未定义
Access Cordova navigator.camera plugin outside of index.html is undefined
似乎找不到对此的解释。我目前使用的是 Visual Studio 2015 RC。安装了相机插件并使用 Cordova 示例作为基础。但是，问题是，如果此代码在 index.html 页面之外，我将无法访问该插件。
我试过在第二页上引用 Cordova.js，但没有用。如何在 index.html 之外访问相机插件？这是我在 Cordova 示例中使用的代码：

编辑：我发现我在索引页上创建的按钮使用：
window.location = path;
当我将此按钮更改为锚标记时，索引页面中的 javascript 保持加载状态，我可以在另一个页面上访问相机。然而，这对我来说仍然是个问题，因为我希望能够在 he/she 能够访问下一页和相机之前使用索引页上的 onclick 事件来验证我的用户。这也意味着我将不得不在我不想做的第一页上加载我所有的 javascript 。反正有这个吗？
编辑：可能有用的额外信息。我使用 Visual Studio 2015 RC 安装了插件。创建一个空白的 Cordova 应用程序并通过双击 config.xml > Plugins > Camera > Add 安装插件。我的 config.xml 看起来像这样：

当使用锚点或 window.location.href 导航到第二页时，这不会在使用 Cordova 4.3.0 和 VS 2015 RC 的简单项目上重现。如果您确实要导航到另一个页面，则需要确保在第二个页面上添加 cordova.js 脚本引用。请参阅下面的说明此工作原理的页面。
发生的情况很可能是以下情况之一：
- "Single page app" JavaScript 框架通常会向锚点等元素添加事件侦听器，这样当您单击它们时，它们会在幕后加载页面并使用过渡效果淡入淡出。但是，它所做的实际上是让您从 "window" 的角度保持在同一页面上。 DOM 未卸载，因此您不需要重新加载所有 JS 代码。好的框架也会更新导航历史，这样后退按钮之类的东西就可以工作了。我相信 jQuery 移动是这些框架之一。像这样的 SPA 框架通常提供某种 API 来在后台从代码转换。但是，显式调用 window.location 将绕过您的 JavaScript 框架并导致它转储 DOM 的全部内容，您将不得不重新加载所有 JavaScript包括 cordova.js。 （与从 http://www.microsoft.com to http://www.bing.com 开始没有什么不同。这是一项关键的安全功能。）要解决此问题，您不应使用 window.location 进行导航，而应使用 SPA 框架的导航 APIs进行页面转换。
- 如果您在第二页上引用了 cordova.js 以及所有 JavaScript 代码，您可能在代码的前面遇到了导致负载的 JavaScript 异常cordova.js 不会发生，因为执行因异常而停止。
- 我们刚刚在将某些文件签入源代码管理时发现了一个问题。我们最近发现，签入插件文件夹中的 android.json、windows.json、wp8.json 或 remote_ios.json 文件可能会导致构建成功但插件不成功的奇怪行为功能。存在问题的唯一迹象是您将在输出 window 中看到异常。参见
看到这个正常工作。将这些文件添加到一个空白项目中，然后通过配置设计器添加相机插件，以从第二页查看工作情况。相机将打开，您可以拍照。单击锚点或按钮将移动到第二页，然后执行相同的操作。

当使用锚点或 window.location.href 导航到第二页时，这不会在使用 Cordova 4.3.0 和 VS 2015 RC 的简单项目上重现。如果您确实要导航到另一个页面，则需要确保在第二个页面上添加 cordova.js 脚本引用。请参阅下面的说明此工作原理的页面。
发生的情况很可能是以下情况之一：
- "Single page app" JavaScript 框架通常会向锚点等元素添加事件侦听器，这样当您单击它们时，它们会在幕后加载页面并使用过渡效果淡入淡出。但是，它所做的实际上是让您从 "window" 的角度保持在同一页面上。 DOM 未卸载，因此您不需要重新加载所有 JS 代码。好的框架也会更新导航历史，这样后退按钮之类的东西就可以工作了。我相信 jQuery 移动是这些框架之一。像这样的 SPA 框架通常提供某种 API 来在后台从代码转换。但是，显式调用 window.location 将绕过您的 JavaScript 框架并导致它转储 DOM 的全部内容，您将不得不重新加载所有 JavaScript包括 cordova.js。 （与从 http://www.microsoft.com to http://www.bing.com 开始没有什么不同。这是一项关键的安全功能。）要解决此问题，您不应使用 window.location 进行导航，而应使用 SPA 框架的导航 APIs进行页面转换。
- 如果您在第二页上引用了 cordova.js 以及所有 JavaScript 代码，您可能在代码的前面遇到了导致负载的 JavaScript 异常cordova.js 不会发生，因为执行因异常而停止。
- 我们刚刚在将某些文件签入源代码管理时发现了一个问题。我们最近发现，签入插件文件夹中的 android.json、windows.json、wp8.json 或 remote_ios.json 文件可能会导致构建成功但插件不成功的奇怪行为功能。存在问题的唯一迹象是您将在输出 window 中看到异常。参见
看到这个正常工作。将这些文件添加到一个空白项目中，然后通过配置设计器添加相机插件，以从第二页查看工作情况。相机将打开，您可以拍照。单击锚点或按钮将移动到第二页，然后执行相同的操作。
