无法在文件：///android_asset/www/apis/camera.js：45读取未定义类型的属性“ DATA_URL”

Question

I am very much new to phonegap applications but i am an android developer.I am trying to call camera on a button click in my phonegap application.Following is my html where i am calling take_pic() method of camera.js api javascript.I have included camera.js in body after seeing api example only. 我对phonegap应用程序非常陌生，但我是一名android开发人员。我试图在我的phonegap应用程序中单击按钮时调用camera。以下是我在html中调用camera.js api javascript.I的take_pic（）方法的方法仅在看到api示例后才在体内包含了camera.js。

<body>
<label for="hello">Hello World</label>
<br><input type="submit" id="submit" value="Call Camera" onclick="take_pic();">
<script type="text/javascript" charset="utf-8" src="apis/camera.js"></script>
</body>

following is the method of camera.js which is triggered but it throws "Can not read propery 'DATA_URL' of undefined type at file:///android_asset/www/apis/camera.js:45" error .Please guys help me out.let me know if more details are required 以下是被触发的camera.js方法，但抛出“无法在file：///android_asset/www/apis/camera.js：45读取未定义类型的属性'DATA_URL'”错误。请大家帮帮我。让我知道是否需要更多详细信息

function take_pic() {
  navigator.camera.getPicture(onPhotoDataSuccess, function(ex) {
    alert("Camera Error!");
  }, { quality : 30, destinationType: destinationType.DATA_URL });
}

Did you try the next code? 您是否尝试了下一个代码？ it is in the PhoneGap API examples: PhoneGap example 它在PhoneGap API示例中： PhoneGap示例

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;
}

function take_pic() {
    navigator.camera.getPicture(onPhotoDataSuccess, function(ex) {
        alert("Camera Error!");
    }, { quality : 30, destinationType: destinationType.DATA_URL });
}

I think your problem is that the variable "destinationType" is undefined. 我认为您的问题是变量“ destinationType”未定义。 Did you initialized it properly? 您是否正确初始化了？
