javascript – Phonegap JQM – Camera API,无法查看捕获的照片

我正在尝试Camera API for Phonegap,我遇到了一个问题.使用官方文档中的代码：

<script type="text/javascript" charset="utf-8">

    var pictureSource;   // picture source
    var destinationType; // sets the format of returned value 

    // Wait for PhoneGap to connect with the device
    //
    document.addEventListener("deviceready",onDeviceReady,false);

    // PhoneGap is ready to be used!
    //
    function onDeviceReady() {
        pictureSource=navigator.camera.PictureSourceType;
        destinationType=navigator.camera.DestinationType;
    }

    // Called when a photo is successfully retrieved
    //
    function onPhotoDataSuccess(imageData) {
      // 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;
    }

    // Called when a photo is successfully retrieved
    //
    function onPhotoURISuccess(imageURI) {
      // Uncomment to view the image file URI 
      // console.log(imageURI);

      // Get image handle
      //
      var largeImage = document.getElementById('largeImage');

      // Unhide image elements
      //
      largeImage.style.display = 'block';

      // Show the captured photo
      // The inline CSS rules are used to resize the image
      //
      largeImage.src = imageURI;
    }

    // A button will call this function
    //
    function capturePhoto() {
      // Take picture using device camera and retrieve image as base64-encoded string
      navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 50 });
    }

    // A button will call this function
    //
    function capturePhotoEdit() {
      // Take picture using device camera, allow edit, and retrieve image as base64-encoded string  
      navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 20, allowEdit: true }); 
    }

    // A button will call this function
    //
    function getPhoto(source) {
      // Retrieve image file location from specified source
      navigator.camera.getPicture(onPhotoURISuccess, onFail, { quality: 50, 
        destinationType: destinationType.FILE_URI,
        sourceType: source });
    }

    // Called if something bad happens.
    // 
    function onFail(message) {
      alert('Failed because: ' + message);
    }

    </script>

我的按钮：

<button onclick="capturePhoto();">Capture Photo</button>

和img标签：

<img style="display:none;width:60px;height:60px;" id="smallImage" src="" />

相机打开正常,拍照没问题,但是,它没有显示在页面上.

我有更多的代码可以让你从相册中选择一个图像,这样可以很好地工作,将它显示在不同的图像标签中.

我相信问题是它无法找到imageData.

拍摄的照片会保存到手机中,并且可以使用其他按钮显示,但我希望它在拍摄照片后直接显示.

我正在使用JQM btw并使用Phonegap：Build web编译器编译我的APK.

解决方法:

关于Phonegap的文档是错误的.要获取base64编码的图片,您需要调用

 navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality:50, destinationType:Camera.DestinationType.DATA_URL });
