從圖庫中獲取圖像無法在phoneGap中使用

Question

我們需要獲取圖片表格Gallery.So，然后將插件添加到我們的應用中，然后我們嘗試像這樣

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);
      }

但是我們無法打開ondevicereday頁面加載“ ondevicereday ”警報時顯示，然后我們單擊openGallery按鈕，它顯示justOpen警報，但我們無法打開，所以請指導我們，告訴我代碼中有什么錯誤

我已經使用cordova的File API插件實現了此功能，該File API插件可以讓您訪問Android Phone中的文件系統。

        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

                window.imagePicker.getPictures(
                function(results) {
                    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>

這個簡單的示例從本地存儲中獲取一張圖像，並將其顯示在應用程序的屏幕上，您可以繼續將圖像從uri轉換為base64並像您一樣使用它。現在，這會將已拍攝的圖片填充到html ..希望這會有所幫助。
