jQuery Supersized：如何使用从LI创建的数组？

Question

i'm using the Jquery Supersized plugin and wanted a better way of creating the list of images used.

i found this same question here jQuery Supersized: Load images from LI but i'm having trouble implementing the solution.

i have a UL with the names of the images like this :

<ul id="slide_list">
<li><div class="slide_src">pic1.jpg</div>
<div class="slide_head">head 1</div></li>

<li><div class="slide_src">pic2.jpg</div>
<div class="slide_head">head 2</div></li>

<li><div class="slide_src">pic3.jpg</div>
<div class="slide_head">head 3</div></li>

</ul>

i then use the code jfriend00 provided to create an array from this list :

var slides = [];           
$("ul .image").each(function() {
    var this$ = $(this);
    var obj = {};
    obj.image = this$.text();
    obj.title = this$.nextAll(".slide_src").text();
    obj.thumb = this$.nextAll(".slide_head").text();
    slides.push(obj);
});​​​​​​​​​​​​​​​

my problem is that when i try to use this slides array in the supersized script it gives me an error "'slides' is undefined"

my supersized code looks like this :

jQuery(function($){
    $.supersized({

        //Functionality
        slideshow               :   1,      //Slideshow on/off
        autoplay                :   1,      //Slideshow starts playing automatically
        start_slide             :   1,      //Start slide (0 is random)
        random                  :   0,      //Randomize slide order (Ignores start slide)
        slide_interval          :   5000,   //Length between transitions

        //Components
        navigation              :   0,      //Slideshow controls on/off
        thumbnail_navigation    :   0,      //Thumbnail navigation
        slide_counter           :   0,      //Display slide numbers
        slide_captions          :   0,      //Slide caption (Pull from "title" in slides array)
        slides                  : slides
    }); 
});

(i've removed some of the supersized option code for brevity).

showing the content of slides array in the console shows me
[object Object],[object Object],[object Object] so i know i'm doing something wrong...

if i use this : slidesDisp = JSON.stringify(slides)

then the array is shown perfectly in the console, [{"image":"pic1.jpg","title":"head 1"},{"image":"pic2.jpg","title":"head 2"},{"image":"pic3.jpg","title":"head 3"}] but when i use it in the supersized script nothing happens

slides: slidesDisp

any suggestions to what i'm doing wrong?

Your HTML does'nt match your javascript, you don't have an .image class, and make sure you don't initalize the supersized plugin in a different DOM ready scope :

$(function() {

    var slides = [];    

    $("ul .slide_src").each(function() {
        var $this = $(this);
        var obj = {};
        obj.image = $this.text();
        obj.title = $this.next(".slide_head").text();
        slides.push(obj);
    });​​​​​​​​​​​​​​​

    $.supersized({
        // ...........other options
        slides                  : slides
    });
});
