Supply images for slideshow dynamically from HTML (jQuery map/get)

Question

I am using awesome plugin jQuery BackStretch for my background slideshow. This is the common way how to pass images to it.

$.backstretch([
    "http://dl.dropbox.com/u/515046/www/outside.jpg", 
    "http://dl.dropbox.com/u/515046/www/garfield-interior.jpg", 
    "http://dl.dropbox.com/u/515046/www/cheers.jpg"
], {duration: 3000, fade: 750});

I don't want to supply images for it by hardcoding though, I want the function to grab what my PHP generates inside that container. Here's what I have so far.

var images = $('#background img').map(function() { return this.src; }).get();
$.backstretch([$images], {duration: 3000, fade: 750});

And that, obviously, doesn't work - according to FireBug, variable images is not defined (?) . although if I "alert" the variable, it shows comma separated urls of images.

Any idea what am I doing wrong? Thank you!

so u want to use `backstretch` from a list of `images` right? Assuming that is `#background img` selector. — Matt Lo, Mar 10 '13 at 07:19

This should be suffice. backstretch is expecting the first argument to be an array of strings that are references to images.

$(document).ready(function () {
    var images = [];

    // iterate over your selection
    $('#background img').each(function () {
        // save source to list
        images.push(this.src);
    });

    // use plugin
    $.backstretch(images, {duration: 3000, fade: 750});
});

Also I'm assuming your HTML is something like this...

<div id="background">
    <img src="http://dl.dropbox.com/u/515046/www/outside.jpg" />
    <img src="http://dl.dropbox.com/u/515046/www/garfield-interior.jpg" />
</div>
