我第一次尝试使用 Cordova 原生插件。我从相机和文档中提供的示例代码开始。 但是，这失败了，并且navigator.camera未定义。
我已经包含了下面的代码。
<div data-role="page" id="CameraPage">
<script type="text/javascript" charset="utf-8">
var pictureSource; // picture source
var destinationType; // sets the format of returned value
// Wait for device API libraries to load
//
document.addEventListener("deviceready",onDeviceReady,false);
// device APIs are available
//
function onDeviceReady() {
pictureSource=navigator.camera.PictureSourceType;
destinationType=navigator.camera.DestinationType;
}
// Called when a photo is successfully retrieved
//
function onPhotoDataSuccess(imageData) {
alert("Photo Data Success");
// Uncomment to view the base64-encoded image data
// console.log(imageData);
// Get image handle
//
var smallImage = document.getElementById('smallImage');
// Unhide image elements
//
smallImage.style.display = 'block';
// Show the captured photo
// The inline CSS rules are used to resize the image
//
smallImage.src = "data:image/jpeg;base64," + imageData;
}
// A button will call this function
//
function capturePhoto() {
alert("function is called");
if(_.isUndefined(navigator.camera)){
alert("Camera is not defined");
}else{
alert("WTF?!");
}
// Take picture using device camera and retrieve image as base64-encoded string
navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 50,
destinationType: destinationType.DATA_URL });
}
// Called if something bad happens.
//
function onFail(message) {
alert('Failed because: ' + message);
}
</script>
<button onclick="capturePhoto();">Capture Photo</button> <br>
<img style="display:none;width:60px;height:60px;" id="smallImage" src="" />
<img style="display:none;" id="largeImage" src="" />
我根据 CLI 说明安装了相机插件
cordova plugin add https://git-wip-us.apache.org/repos/asf/cordova-plugin-camera.git
我还添加了 cordova.js 文件。
<script type="text/javascript" charset="utf-8" src="js/cordova-js/lib/cordova.js"></script>
你在哪里测试你的代码？
我不知道你是否还需要安瑟。但我认为它可以帮助某人。我运行您的代码，它可以 100% 工作。我已经在Android的模拟器中使用模拟相机进行了测试。我认为您忘记了使用权限。
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />
我在这里举了一个例子 https://github.com/paulorbpacheco/CameraTest-Cordova.git
我希望这能帮助你...
问候
这有点旧了，但我想为以后可能出现的任何其他人提供洞察力......
我遇到的问题是由于我曾经在我的系统上完成了较旧的 npm 科尔多瓦安装，然后是 phonegap 的 npm 安装。
Cordova是phonegap的依赖项，因此存在必要的Cordova版本，但是当我运行插件安装时：
cordova plugin add https://git-wip-us.apache.org/repos/asf/cordova-plugin-camera.git
系统默认为旧版本的Cordova，因此无法获得正确版本的插件。
最近当我将 npm phonegap 包从 3.0.0 升级到 3.1.0 时，我再次想起了这个问题。 再一次，插件发生了变化，并且不向后兼容。 在 3.0.0 的情况下，PhoneGap 期望插件目录
org.apache.cordova.core.camera org.apache.cordova.core.X
在最新版本 3.1.0 中，删除了核心命名空间，这些现在看起来像这样
org.apache.cordova.camera org.apache.cordova.X
在正常使用场景中，我认为这不是人们每天都会遇到的事情。 我猜大多数项目都是生成的，开发人员正在添加他们需要的插件并坚持使用特定版本的PhoneGap，直到某个时候他们决定升级项目。 在我看来，当开发人员开始同时处理多个PhoneGap项目时，这成为一个问题;我在这里遇到的案例。 我为新项目升级到较新版本，然后需要向旧项目添加插件 爆炸发生
到目前为止，我一直在使用 PhoneGap 的全球安装（根据 phonegap.com 年的官方文档）
sudo npm install -g phonegap
我的短期解决方案最终是将所需的插件目录从一个使用我需要版本的旧项目中cp到碰巧在同一版本上运行的另一个项目中。 我的下一步将是使用 nvm 进行测试，看看我是否能够以这种方式为每个项目使用 PhoneGap 的多次安装，而不是拥有一个总是不断变化的全局版本。
由于 cordova 未正确构建而产生未定义的问题，因此请按照以下步骤解决 navigator.camera 问题
第 1 步：获取最新的 phonegap zip （http://phonegap.com/install/），现在最新版本是 2.9.1，其中包含 cordova.2.9.1.js ，但没有 cordova2.9.1.jar（您需要生成 jar 文件，请按照步骤 2）
第2步：然后你需要生成cordova2.9.1.jar，按照下面的这个链接如何生成.jar文件科尔多瓦 2.7.0.jar 在哪里？
请记住，您必须在"Eclipse IDE"中的Android项目中拥有适当的cordova.2.9.1.js及其各自的cordova.2.9.1.jar
第 3 步：不要忘记在您的配置中添加相机权限.xml（如果不起作用，请按照 config.xml）
<-------配置.xml>

<widget xmlns = "http://www.w3.org/ns/widgets"

</widget>第 4 步：在您的 AndroidManifest.xml 文件中添加权限
<------->
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

<uses-permission android:name="android.permission.WRITE_CONTACTS" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.BROADCAST_STICKY" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />第 5 步：在您自己的 javascript 文件中添加代码（请检查我的 js 代码）
<-----我的自定义>
$("#btnImageCaptured").on("click", function(e){
alert("image uploading");
e.preventDefault();
e.stopPropagation();
navigator.camera.getPicture(onSuccessImageAttachment, onFailImageAttachment,
{quality:50,
destinationType: Camera.DestinationType.FILE_URI,
sourceType : Camera.PictureSourceType.CAMERA,
//encodingType: navigator.camera.EncodingType.PNG,
allowEdit: true,
targetWidth: 200, targetHeight: 200});
//targetWidth: 100, targetHeight: 150,
//mediaType : Camera.MediaType.PICTURE
//sourceType:navigator.camera.PictureSourceType.PHOTOLIBRARY});
});
function onSuccessImageAttachment(imageData){
window.alert("success");
//window.alert("Prishah took Image successfully : " + imageData);
window.location.href = "#orderAttachedLotImage";
$("#imgAttachedLot").attr('src','data:image/jpeg;base64,' + imageData);
//$("#imgAttachedLot").src = "data:image/jpeg;base64," + imageData;
//TODO : Insert new Image request to the server
//TODO : Display Image
}
function onFailImageAttachment(failMsg) {
window.alert("Failed to image uploading :" + failMsg);
}步骤6（可选）：尝试关闭多任务处理，看看是否有帮助。 在您的 java 应用程序中，加：
super.setBooleanProperty（"keepRunning"， false）;
<------>
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
super.setIntegerProperty("splashscreen", R.drawable.screen_hdpi_portrait);
super.setBooleanProperty("keepRunning", false); //For Camera
super.loadUrl("file:///android_asset/www/index.html", 2000);
//pinch zooming Capabilities
WebSettings ws = super.appView.getSettings();
ws.setSupportZoom(true);
ws.setBuiltInZoomControls(true);
}使用此选项在桌面模式下压制相机
function onDeviceReady() {
try {
pictureSource = navigator.camera.PictureSourceType;
destinationType = navigator.camera.DestinationType;
} catch (e) {
}
}
嗨，
您可以尝试使用 Icenium http://www.icenium.com/并在那里创建一个Phonegap项目，其中已经完成了带有相机 API 的示例应用程序，您可以在那里找到代码。
希望这有帮助
