phonegap学习笔记1——创建工程 使用插件

来源:互联网 发布:无尽之剑3宝石数据修改 编辑:程序博客网 时间:2024/05/01 11:26

cordova create hello com.zyt.hello "hello"

cd hello

cd plugins

cordova plugin add org.apache,cordova.camera("org.apache,cordova.camera"区分大小写)

至此工程成功创建,插件文件成功添加到了plugins目录下

修改androidmanifest.xml文件,添加权限

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

修改config.xml添加插件

<plugin name="Camera" value="org.apache.cordova.camera" />

value的值根据\hello\plugins\org.apache.cordova.camera目录下的plugin.xml中id="org.apache.cordova.camera"来定。

至此可以在网页文件中调用摄像头了,官方demo:

<!DOCTYPE html>

    <script type="text/javascript" charset="utf-8" src="cordova.js"></script>
    <script type="text/javascript" charset="utf-8">

      navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 50,

    }
