"lat": -111,
"lng": 40
// }
// @param errorCallback callback function which will get the error
navigator.localassets.getAllPhotos(successCallback, errorCallback)getThumbnails
///
// Gets base64encoded thumbnails data for a given list of photo urls
// @param idList Array of string ids, for example: [photometa[0].id] or [photometa[0].id,photometa[1].id]
// @param successCallback callback function which will get the array with json objects in the following format:
// {
// "id": id,
"date": seconds Since 1970,
"lat": -111,
"lng": 40
"data": base64encoded,
"orientation": 3
// }
// @param errorCallback callback function which will get the error
navigator.localassets.getThumbnails(idList, successCallback, errorCallback)getPhoto
///
// Gets base64encoded photo data for a given photo. You can specify the max width or height
// @param id The id of the photo to get a large version of
// @param maxSize The max width or height (based on photo dimensions) of the resized photo.
// @param successCallback callback function which will get the json object in the following format:

// @param errorCallback callback function which will get the error
navigator.localassets.getPhoto(id, maxSize, successCallback, errorCallback)All examples assume you have successfully added phonegap-plugin-localassets to your project
To get an iOS photo library meta data use getAllPhotoMetadata:
getAllPhotos:function() {
if (navigator.localassets) {
navigator.localassets.getAllPhotos(this.onGetAllPhotosSuccess, this.onGetAllPhotosError);
}
},
onGetAllPhotosSuccess:function(data){
this.photometa = data;
alert("onGetAllPhotosSuccess\n" + data.length);
},
onGetAllPhotosError:function(error){
console.error("onGetAllPhotosError > " + error);
}To get one or more thumbnails for a list of asset url's:
getThumbnails:function(idList, successCallback, errorCallback){
if (navigator.localassets) {
navigator.localassets.getThumbnails(idList, this.onGetThumbnailsSuccess, this.onGetThumbnailsError);
}
},
onGetThumbnailsSuccess:function(data){
this.thumbnails = data;
alert("onGetThumbnailsSuccess\n" + data.length);
},
onGetThumbnailsError:function(error){
console.error("onGetThumbnailsError > " + error);
}To get full sized photo for a photo id:
getPhoto:function(id, maxSize, successCallback, errorCallback){
if (navigator.localassets) {
navigator.localassets.getThumbnails(id, maxSize, this.onGetPhotoSuccess, this.onGetPhotoError);
}
},
onGetPhotoSuccess:function(data){
this.thumbnails = data;
alert("onGetThumbnailsSuccess\n" + data.length);
},
onGetPhotoError:function(error){
console.error("onGetThumbnailsError > " + error);
}
