如何显示科尔多瓦从相机拍摄的图像? (Xcode / iOS)

[英]How to show image taken from camera in Cordova? (Xcode/iOS)

I am able to access the camera and even save the image remotely, but I would like to show the image on the screen before I upload. 我可以访问相机,甚至可以远程保存图像,但是我想在上传之前在屏幕上显示图像。

The function that opens the devices camera is: 打开设备摄像头的功能是:

function capturePhoto() {
                    navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 10, width: 412, height: 412, correctOrientation: 1, saveToPhotoAlbum: 1});
                }

The function that is triggered after the photo is initially taken is: 最初拍摄照片后触发的功能是:

  function uploadImage() {
                imageURI = lastImage;

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

                smallImage.src = "data:image/jpeg;base64," + imageURI;


                var fail, ft, options, params, win;

                // callback for when the photo has been successfully uploaded:
                var success =  function(response) {
                    //alert(tags);
                    alert("Photo Saved");
                };

                // callback if the photo fails to upload successfully.
                var fail = function(error) {
                    alert("An error has occurred: Code = " + error.code);
                    alert(FileTransferError.CONNECTION_ERR);
                };
                 //FILE UPLOAD SCRIPTS
                options = new FileUploadOptions();
                options.fileKey = "my_image";
                options.fileName = imageURI.substr(imageURI.lastIndexOf('/') + 1);
                options.mimeType = "text/plain";
                params = {
                    val1: tags,
                    val2: location
                };
                options.params = params;
                ft = new FileTransfer();
                ft.upload(imageURI, 'http://mysite.com/recieve.php', success, fail, options);

            }

And the HTML where the image is to be displayed: 以及要显示图像的HTML:

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

I am assuming there is something wrong with the line 我假设这条线有问题

            smallImage.src = "data:image/jpeg;base64," + imageURI;

but I am not sure what or how to fix it. 但我不确定该如何解决。

Would anyone know how to ammend this? 有人会知道如何修改吗?

I got it. 我知道了。

I changed the line 我换了线

 smallImage.src = "data:image/jpeg;base64," + imageURI;

too

 smallImage.src = imageURI;
