Javascript 从库中获取图像在phoneGap中不起作用

javascript jquery cordova camera

Javascript 从库中获取图像在phoneGap中不起作用,javascript,jquery,cordova,camera,cordova-plugins,Javascript,Jquery,Cordova,Camera,Cordova Plugins,我们需要得到图像表格库。所以我们添加插件到我们的应用程序，然后我们像这样尝试 var pictureSource; // picture source var destinationType; // sets the format of returned value document.addEventListener("deviceready",onDeviceReady,false); function onDeviceReady() { alert("ondev

我们需要得到图像表格库。所以我们添加插件到我们的应用程序，然后我们像这样尝试

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);
      }

但我们无法打开图库。当页面加载“

ondevicereday

”警报显示时，我们单击

openGallery

按钮，它将显示

justOpen

警报，但我们无法打开

因此，请指导我们并告诉我代码中有什么错误

我已经使用cordova的文件API插件导入了它，该文件API插件将允许您访问Android手机中的文件系统

这个简单的示例从本地存储器中获取一张图像，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，并按自己喜欢的方式使用。现在，这将把已经拍摄的照片填充到html中。希望这有帮助。
重命名onPhotoDataSuccess
为onPhotoURISuccess@Naveen Dodda您解决了吗？
