JavaScript Explanation

There are 2 main functions in this sample app which will be explained as follows:

jsonFlickrFeed()

jsonFlickrFeed() is fired when the Flickr API is loaded. The Flickr API is called when the index.html file is loaded. Inside the header of index.html file, there is a line:
<script src="http://api.flickr.com/services/feeds/photos_public.gne?format=json" defer></script>
This is where the Flickr API is called. In this function, the retrieved photos are then pushed into a local variable images and the photos are display as a slide show by calling displayPicture() function every 1 second. Below is the JavaScript code of this function:
var images = [];
// This function is fired when the Flickr API is loaded.
function jsonFlickrFeed(result) {
for (var j in result.items) {
var img = result.items[j].media.m;
images.push(img);
}
// display next photo every 1 second
setTimeout(displayPicture, 1000);
}

displayPicture()

displayPicture() displays the photos stored inside images variable (photos retrieved from Flickr) in a container created by HTML code in index.html file. Below is the JavaScript code of this function:
//Display the retrieved photos from Flickr as a slide show
function displayPicture() {
$("#container").css("visibility", "hidden");
var $ul = $("<ul>");
for(var j in images) {
var srcUrl = images[j];
li = '<li><img src="' + srcUrl + '" id ="list" width="60%" /></li>';
$ul.append($(li));
}
$("#container").append($ul);
//Setting for photo sliding animation
$ul.bxSlider({
auto: true,
pager: false,
speed: 500,
pause: 1800,
controls: false,
});
$("#loadSpinner").remove();
$("#container img").addClass("shadow");
setTimeout(function() {
$("#container").css("visibility", "visible");
}, 1000);
}
