jQuery/JavaScript to replace broken images

Question

I have a web page that includes a bunch of images. Sometimes the image isn\'t available, so a broken image is displayed in the client\'s browser.

How do I use jQuery

Answer 1

Here is an example using the HTML5 Image object wrapped by JQuery. Call the load function for the primary image URL and if that load causes an error, replace the src attribute of the image with a backup URL.

function loadImageUseBackupUrlOnError(imgId, primaryUrl, backupUrl) {
    var $img = $('#' + imgId);
    $(new Image()).load().error(function() {
        $img.attr('src', backupUrl);
    }).attr('src', primaryUrl)
}
