Cordova：在哪里以及如何安装插件？(Cordova: where and how install a plugin?)

Cordova：在哪里以及如何安装插件？(Cordova: where and how install a plugin?)

我创建了一个全新的应用程序。

然后我去了www目录并执行了npm install cordova-plugin-file 。

现在？ 在应用程序中使用此插件我该怎么办？

如果我做一个cordova plugin list它只向我显示白名单插件，默认情况下从cordova本身创建。

然后我尝试了cordova plugin add cordova-plugin-file ，现在cordova plugin list显示了白名单和文件插件。

现在？ 当我尝试以下代码时，我得到了，在Android模拟器上，cordova.file undefined

window.resolveLocalFileSystemURL(cordova.file.dataDirectory, function(dir) { console.log("got main dir", dir); });

I created a fresh new app.

Then I went to the www directory and executed npm install cordova-plugin-file.

And now? What must I do to work with this plugin in the app?

If I do a cordova plugin list it shows me only the whitelist plugin, created by default from cordova itself.

I then tried cordova plugin add cordova-plugin-file and now cordova plugin list shows me both whitelist and file plugin.

And now? When I tried the following code I got that, on Android emulator, cordova.file is undefined

window.resolveLocalFileSystemURL(cordova.file.dataDirectory, function(dir) { console.log("got main dir", dir); });

最满意答案

cordova-plugin-file插件仅适用于真实手机，不适用于模拟器。

您可以将应用安装到手机上并进行调试。

在控制台中，您将获得预期的日志。

The problem here was simply that the whole app must be wrapped into the deviceReady event handler, but ... not this code ... damn... now it works
