I’ve been trying out PhoneGap on iOS using the following example code from the documentation. Now I want to add the source of the image last taken to the text area. If I have understood it correctly, the destinationType.FILE_URI is the file path, but how can I pass that as a string to the text area upon photo success?

Get source:

        function getPhoto(source) {
            // Retrieve image file location from specified source
            navigator.camera.getPicture(onPhotoURISuccess, onFail, { quality: 50, 
                                        destinationType: destinationType.FILE_URI,
                                        sourceType: source });
        }

Complete code:

    It would seem that your onPhotoURISuccess(imageURI) function would be the best place to put that code. I see that there is already a console.log that is commented out for this. Instead, you could do something like:

    $("#ELEMENT_WHERE_YOU_WANT_TO_SEE_URI").text( imageURI );

    Where the big upper case selector is the id of the HTML element that you would like to populate the image URI with. Is that the #textarea element? That should be fine to add that anywhere inside your onPhotoURISuccess() function.
