Javascript slideshow in random order -


my slideshow displays images in non-random order @ moment, i'd random.

jsfiddle:

http://jsfiddle.net/6hcaj/

javascript:

function loadnextimage(userandomselection) {         if(imagepool.length > 0) {         if(userandomselection) {             var randomindex = math.floor(math.random() * imagepool.length);             var imgdata = imagepool.splice(randomindex,1);         } else {             var imgdata = imagepool.shift();         }          $(".back-image-container").append("<img id='back-image-" + imgdata.id + "' class='back-image' src='" + imgdata.url + "'/>");          var imgobj = $("#back-image-" + imgdata.id);                 imgobj.hide();          if ( imgobj.complete || imgobj.readystate == 4 || imgobj.readystate == "complete") {             loadcompleted(imgobj,userandomselection);         } else {             imgobj.load(function() {                 loadcompleted(imgobj,userandomselection);                  });         }     } }

html:

<div class="back-image-container">     <img id="back-image-0" class="back-image" src="http://cdn2.bigcommerce.com/n-pktq5q/b2aus7wd/product_images/theme_images/scorpiongoldberlin.jpg?t=1403886381" style="width: 1347px; height: 898px; left: -63px; display: inline;">     <img id="back-image-1" class="back-image" src="http://cdn2.bigcommerce.com/n-pktq5q/b2aus7wd/product_images/theme_images/brelingirlcross2.jpg?t=1403886381" style="width: 1347px; height: 898px; left: -63px; display: none;">     <img id="back-image-2" class="back-image" src="http://cdn2.bigcommerce.com/n-pktq5q/b2aus7wd/product_images/theme_images/brelinafternoon.jpg?t=1403886381" style="width: 1347px; height: 898px; left: -63px; display: none;"> </div>

i don't think problem in loadnextimage, way called. notice loadnextimage has parameter defines if order should random or not.

in fiddle call loadnextimage done such:

loadnextimage(false);

this means random behavior bypassed. try inverting boolean value:

loadnextimage(true);

also, line seems have error:

var imgdata = imagepool.splice(randomindex,1);

splice returns array of results removed, because there can more one. in case returning array single item, image data shifted. fix reference need first element of array:

var imgdata = imagepool.splice(randomindex,1)[0];

with these changes slide functions correctly.
