從畫廊得到圖像中的PhoneGap

不能正常工作，我們需要得到的圖像格式Gallery.So我們加入插件，我們的應用程序，然後我們試圖這樣從畫廊得到圖像中的PhoneGap

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); 
     }

但我們無法打開gallery.When頁面載入「ondevicereday 「警報顯示，然後我們點擊openGallery按鈕，它顯示justOpen警報，但我們無法打開所以請指導我們，告訴我什麼錯碼

任何錯誤跟蹤？ – Gandhi

重命名'onPhotoDataSuccess'爲'onPhotoURISuccess' – Akis

@Naveen Dodda你設法解決？ – IamKarim1992

我已經impalmented科爾多瓦這個使用文件API插件，文件API插件會讓你訪問Android手機中的文件系統。

     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

       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>

這個簡單的例子，從本地存儲需要一個單一的圖像，並顯示其應用程序的屏幕上，U可以繼續前進，將圖像從URI爲base64轉換並使用它作爲你喜歡的。現在這將填充已經採取的圖片到HTML ..希望這有助於。
