Using jQuery to tidy up missing Images

I’m working on a page that pulls photo’s from a file share on a server by the format of “firstname-lastname-dept.png”. Now 9 times out of 10 this works fine but on the odd occasion an image doesn’t exist.  Now I could do it via c# in code behind to check it exists or I could do it via jQuery.  For this post I am going to do it with jQuery as we could really build upon this post quite easily.

Before we capture the missing Images

I’ve created a simple page with BootStrap and get the following:

Photo Viewer jQuery Image Loaded Not Found

As you can see 2 of the images aren’t found and the alt tag is displayed. This can easily be avoided by adding a couple lines of jQuery magic.

Adding in the jQuery capture

For this we’re going to be using the function “error”.

The error event is sent to elements, such as images, that are referenced by a document and loaded by the browser. It is called if the element was not loaded correctly. * find here –

A very simple implementation is as follows:

[code lang=”js”]
$(function () {
if ($.browser.msie) {
$(‘img’).each(function () {
if (this.readyState == ‘uninitialized’) {
$(this).attr(‘src’, ‘images/not-found-image.jpg’);
$(‘img’).error(function () {
$(this).attr(‘alt’, ‘image not found’).attr(‘src’, ‘images/not-found-image.jpg’);

Internet Explorer doesn’t like the Error function so I added a check (line 3-7). After the DOM has loaded it goes through each of the images on the page and checks the readyState. Any images not loaded will be replaced with the not-found-image.

With the above in place we get a nicer look and feel to the page with further options available should we wish to take this little project further.

Photo Viewer jQuery Image Loaded Replaced

I have had a couple of ideas in which I am going to expand on this, I’ll be posting these shortly.
