从图库中获取图像无法在phoneGap中使用

Question

我们需要获取图片表格Gallery.So，然后将插件添加到我们的应用中，然后我们尝试像这样

var pictureSource;   // picture source
   var destinationType; // sets the format of returned value
 document.addEventListener("deviceready",onDeviceReady,false);
 function onDeviceReady() {
        alert("ondevicereday");
        pictureSource=navigator.camera.PictureSourceType;
        destinationType=navigator.camera.DestinationType;
    }
   function onPhotoDataSuccess(imageData) {
    alert("Open");
      var smallImage = document.getElementById('smallImage');
      smallImage.src = "data:image/jpeg;base64," + imageData;
    }
 function capturePhoto(){
    alert("justOpen");
    navigator.camera.getPicture(onPhotoURISuccess, onFail, { quality: 50,
        destinationType: destinationType.FILE_URI,
        sourceType: Camera.PictureSourceType.PHOTOLIBRARY });

     }
     function onFail(message) {
        alert('Failed because: ' + message);
      }

但是我们无法打开ondevicereday页面加载“ ondevicereday ”警报时显示，然后我们单击openGallery按钮，它显示justOpen警报，但我们无法打开，所以请指导我们，告诉我代码中有什么错误

我已经使用cordova的File API插件实现了此功能，该File API插件可以让您访问Android Phone中的文件系统。

        Some notes:
            * gap: is required only on iOS (when using UIWebView) and is needed for JS->native communication
            * https://ssl.gstatic.com is required only on Android and is needed for TalkBack to function properly
            * Disables use of inline scripts in order to mitigate risk of XSS vulnerabilities. To change this:
                * Enable inline JS: add 'unsafe-inline' to default-src

                    console.log(results);
                        for (var i = 0; i < results.length; i++) {
                        var imageUri=results[i];
                        console.log('Image URI: ' + results[i]);
                        lastPhotoContainer.innerHTML = "<img src='" + imageUri + "' style='width: 75%;' />";
                        }
                    }, function (error) {
                        console.log('Error: ' + error);
                }
            );
            }
        </script>
    </body>
</html>

这个简单的示例从本地存储中获取一张图像，并将其显示在应用程序的屏幕上，您可以继续将图像从uri转换为base64并像您一样使用它。现在，这会将已拍摄的图片填充到html ..希望这会有所帮助。
