我在我的javascript项目中使用cordova处理相机功能。我在我的项目中使用了cordova.js和camera.js文件。但是当我调用camera.js的getPicture()函数时,它在我的设备中无效。你可以在我的html中找到我试过的以下代码。请帮助我实现这个目标。提前致谢。
<!DOCTYPE html>
<html lang="en">
<head>
<script src="cordova.js" type="text/javascript" ></script>
<script src="Camera.js" type="text/javascript" ></script>
<script language="javascript">
var pictureSource;
var destinationType;
document.addEventListener("deviceready",onDeviceReady,false);
function onDeviceReady() {
pictureSource=navigator.camera.PictureSourceType;
destinationType=navigator.camera.DestinationType;
}
function onPhotoDataSuccess(imageData) {
var smallImage = document.getElementById('smallImage');
smallImage.style.display = 'block';
smallImage.src = "data:image/jpeg;base64," + imageData;
}
function capturePhoto() {
navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 50,
destinationType: destinationType.DATA_URL });
}
function getPhoto(source) {
navigator.camera.getPicture(onPhotoURISuccess, onFail, { quality: 50,
destinationType: destinationType.FILE_URI,
sourceType: source });
}
function onFail(message) {
alert('Failed because: ' + message);
}
document.getElementById('cam1').innerHTML='<a href="javascript:void(0)" onclick="capturePhoto()"><img src="../images/camera_up.gif" alt="img" width="23" height="20" border="0" id="smallImage" /></a>';
</script>

尝试通过命令控制台安装插件,找到您的项目,然后使用此命令。
cordova插件添加cordova-plugin-camera
cordova插件添加org.apache.cordova.camera
此命令会自动在config.xml中添加引用
删除此引用:
<script src="Camera.js" type="text/javascript" ></script>
