jQuery Won't run

Hey Experts,

I'm trying to get my first jQuery to run. I have attached a zip file of the problem code and a summary is below:

I have this in the HTML file:

...
<link href="css/main.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" src="javascript/jquery-1.7.2.min.js"></script>
<script type="text/javascript" src="javascript/functions.js"></script>
</head>
<body onload="animateMLAR();">
...

I have this in the functions.js file:

$(document).ready(function(){
      function animateMLAR(){
            $('#Mamma').animate({backgroundPosition: '(-500px -80px)'}, 20000);
      }
}

And these are the properties in the CSS file:

#Mamma {
background: url(../images/ML.png) no-repeat center top;
width: 450px;
height: 583px;
float: right;
margin-right: 60px;
margin-top: -20px;
}


Any help would be great!

change this:
<body onload="animateMLAR();">

to this:
<body>

and this:
$(document).ready(function(){
      function animateMLAR(){
            $('#Mamma').animate({backgroundPosition: '(-500px -80px)'}, 20000);
      }
}

Open in new window

to this:
$(document).ready(function(){
      function animateMLAR(){
            $('#Mamma').animate({backgroundPosition: '(-500px -80px)'}, 20000);
      }
      animateMLAR();
}

PS: the thing is, "body onLoad" is run when the document loads.
However, the DOM isn't yet fully "grown up" inside the browser.
That's why jQuery provides $(document).ready

It sounded promising, but it still didn't do anything. Any further suggestions?

Here is the updated package.

Thanks in advance.

check your syntax... you are lacking a closing bracket in functions.js

OK, found several issues with your approach.  

The most important - you need to include the Background Position plugin in your project.  Moving the background is not a built-in feature of jquery.

Second, there were a bunch of little typos in your jquery.

Finally, the function to run the animation is best left *outside* of the $(document).ready() section.

So, the head of your HTML page would look like this:
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Mamma Lenny and the Remedy Official Site</title>
<link href="css/main.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" src="javascript/jquery-1.7.2.min.js"></script>
<script type="text/javascript" src="http://www.protofunc.com/scripts/jquery/backgroundPosition/jquery.backgroundPosition.js"></script>
<script type="text/javascript" src="javascript/functions.js"></script>
</head>

Open in new window


And your jquery section like this:
$(document).ready(function () {
    animateMLAR(); 
});

function animateMLAR(){
    $("#Mamma").animate({ backgroundPosition: "-500px -80px" }, 2000);

}

Wow that got it working! I made the same changes in my MVC version of the site and nothing is working again it is driving me crazy! Any ideas? How do you troubleshoot this stuff?

You need Visual Studio with MVC to see the solution. It is double zipped because Experts Exchange is dumb like that.

Using this:

$(document).ready(function () {
    animateMLAR();
});

function animateMLAR() {
    $("#Mamma").animate({ backgroundPosition: "-500px -80px" }, 2000);
}
                         

It says in Firebug that I have 'missing ) after argument list'

try this:

function animateMLAR() {
    $("#Mamma").animate({ 'background-position-x': '-500', 'background-position-y': '-80' }, 2000);
}
