我对网络作品相当陌生。我正在尝试让相机 api 工作，但我不断收到错误消息：
支持的错误：TypeError：'未定义'不是对象（评估'blackberry.media.camera'）
我尝试使用的页面位于托管服务器上。代码如下：
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<meta name="viewport" id="viewport" content="height=device-height,width=device-width,user-scalable=no" />
<script language="javascript" type="text/JavaScript" >
function takePicture() {
try {
blackberry.media.camera.takePicture(successCB, closedCB, errorCB);
} catch(e) {
alert("Error in supported: " + e);
}
}
function successCB(filePath) {
document.getElementById("path").innerHTML = filePath;
//alert("Succeed: " + filePath);
}
function closedCB() {
// alert("Camera closed event");
}
function errorCB(e) {
alert("Error occured: " + e);
}
</script>
<title>Camera Test Widget</title>
</head>
<body >
<p>Test the Camera by pressing the button below</p>
<b><a href="#" onclick="takePicture();">Take a Picture</a></b>
<div id="path"></div>
</body>
</html>
而我的 config.xml 文件如下：
<?xml version="1.0" encoding="UTF-8"?>
<widget xmlns="http://www.w3.org/ns/widgets"

<feature id="blackberry.media.camera" />
</access>
<name>Flyloops.net</name>
<description>This is a sample application.</description>
<content src="index.html"/>
</widget>
该页面托管在：http ://www.flyloops.net/mobile/bb/camera.html
在过去的 3 个小时里，我一直在扯头发……任何帮助将不胜感激。
