I'm updating a div in a page using jquery mobile in order to play some animations.
The animations also play sound through use of document.createElement('audio');
My problem is, when I update the page to another animation, the old sound keeps playing.
Sorry, this is my first question and if it seems like im not phrasing it properly I apologise.
Here is my code..
Here is the code of the animation to be loaded into the #animation div
<!DOCTYPE HTML>
<html>
<head>
<style>
body {
margin: 0px;
padding: 0px;
}
</style>

<div id="container"></div>
<script src="scripts/kinetic-v4.3.2.min.js"></script>
<script src="scripts/jquery-1.9.1.js"></script>

/*BABY SCENE*/
var stage = new Kinetic.Stage({
container: 'container',
width: 578,
height: 400
});
var babyLayer = new Kinetic.Layer();
var backLayer = new Kinetic.Layer();
var imageObj = new Image();
var backObj = new Image();
imageObj.onload = function() {
var baby = new Kinetic.Image({
x: stage.getWidth() / 2 -100 ,
y: stage.getHeight() / 2 -100,
image: imageObj,
width: 200,
height: 200,
opacity: 0.0
});
var background = new Kinetic.Image({
x: 0,
y: 0,
image: backObj,
width: 578,
height: 400,
opacity: 0.0
});
// add the shape to the layer
babyLayer.add(baby);
backLayer.add(background);
// add the layer to the stage
stage.add(babyLayer);
stage.add(backLayer);
babyLayer.moveToTop();
babyLayer.draw();

Here is the main page code. It gets the filename of the animation page to be loaded into #animation from an array when you click the next button.
<div id="nav" data-role="content" style="width: 600px; margin: 0 auto; text-align: center; position: relative; top:450px">
<a href="#animation" data-role="button" data-inline="true" id ="back">Back</a>
<a href="#animation" data-role="button" data-inline="true" data-theme="b" id="next">Next</a>
<script>
var count=0;
var link_array = ['baby', 'bed', 'book', 'cat', 'chair', 'daddy', 'dog', 'mummy', 'shoe', 'teddy'];
$("#next").click(function(e) {
if(count!==9)
{
$('audio').stop();
count+=1;
}
$('#animation1wl').load('../Animations/' + link_array[count] + '.html');
$('#animation1wl').trigger('create');
});
$("#back").click(function(e) {
if(count !==0)
{
count-=1;
}
$('#animation1wl').load('../Animations/' + link_array[count] + '.html');
$('#animation1wl').trigger('create');
});
</script>
</div>
<div id="animation" data-role="content" style="width: 600px; margin: 0 auto; text-align: left">Problem Loading Resource LNW</div>
When I click the forward or back buttons, I want the audio from the previous animation loaded into #animation to stop playing..
Here is the code rendered inside #animation
<div id="animation1wl" data-role="content" style="width: 600px; margin: 0 auto; text-align: left" class="ui-content" role="main">
<style>
body {

Any help would be great..
Thanks very much.
You can do something like this:
$('audio').each(function(){
this.pause(); // Stop playing
this.currentTime = 0; // Reset time
});
Ihad to rewrite the code but, I got this working in the end by loading the animation in its entirety when you click on the next button rather than just updating a single div.
It's a workaround but at least its working now.
Thanks to Omar who helped a lot with this problem.
