I'm a bit new with javascript/jquery. I've taken over a page design with images and links that animate on rollovers. I've almost got things working, but there's one last glitch. The mouseover effects of an image growing/shrinking work fine when the page is first loaded. But if the user clicks on a link, a secondary animation fires, and an embedded page is loaded. If they click to return to the "main page" the original growing/shrinking rollover animation no longer fires. I'm positive it's because the page has already passed the onload, but I don't know how to fix this. Here's a stripped down version of my jquer:

$(document).ready(function(){

/* now the image animations */


var $width_one = $("#sq1").width();
var $height_two = $("#sq2").height();
var $height_three = $("#sq3").height();
var $width_three = $("#sq3").width()
var $width_four = $("#sq4").width();
var $height_four = $("#sq4").height();

/* this following is the portion that will no longer work after they've clicked on things */

 $(".square.one,#link_nest").mouseenter(function(){

    if ($(".the-nest")[0]){
        $("#link_nest").css({color:"#153d53",fontWeight:"400"},100);
        }
    else{

        $(".square.one").filter(':not(:animated)').animate({width:"150px"},200);
        $("#link_nest").css({color:"#153d53",fontWeight:"400"},100);
        $("#square_caption1").css('visibility','visible');
    } 
 });


 $(".square.one,#link_nest").mouseleave(function(){
    if ($(".the-nest")[0]){
        $("#link_nest").css({color:"black",fontFamily: "Source Sans Pro",fontWeight:"300"},100);
    }
    else{
        $(".square.one").filter(':not(:animated)').animate({width:$width_one},200);

        $("#link_nest").css({color:"black",fontFamily: "Source Sans Pro",fontWeight:"300"},100);
        $("#square_caption1").css('visibility','hidden');
    }

 });

  /* several other, like this. This ends the section that won't run. */

/* now starts the onclick animation. After this runs, and they click on the link that repositions the page back to the "home page" the above animation no longer fires */

$('.square-container').on('click', '.square', function(event) {


    if ( $(this).hasClass('active') ) {

            $('.details h1').animate({ opacity: 0 }, 600, function() { $('.details h1').html(' '); });
            $('.details .article').animate({ opacity: 0 }, 600, function() { $('.details .article').unload(); });
            $('.one').stop().animate({ width: '135', height: '207', left: '648', top: '190', opacity: 1}, 600, function() { /*animation completed*/ });         
            $('.two').stop().animate({ width: '154', height: '208', left: '485', top: '125', opacity: 1}, 600, function() { /*animation completed*/ });
            $('.three').stop().animate({ width: '245', height: '145', left: '231', top: '170', opacity: 1}, 600, function() { /*animation completed*/ });   
            $('.four').stop().animate({ width: '190', height: '139', left: '413', top: '340', opacity: 1}, 600, function() { /*animation completed*/ });
            $('.square').removeClass('active');


        } else if ( $(this).hasClass('one') ) {

            $('.square').removeClass('active');
            $(this).addClass('active');

        }   /*again, several other rollovers,then … */

            else {          
            alert('nothing');
        }       

    });
});

tuperntyne, you forgot to add the jQuery reference is the left panel. That's why it didn't work.

I updated it for you, check: http://jsfiddle.net/Z4hZh/2/

I tested the animations and it all seemns to work, verify if theres any problem there please.

strange... The animations are working in jsfiddle. Yet not so on my own location. that's a bummer. :(

Did you tried other browsers in your local env?

Try replacing

$(".square.one,#link_nest").mouseenter(function(){

with

$(document).on(".square.one,#link_nest", 'mouseenter', function(){

actually, I ended up reworking the entire animation and... hah! Now I have the exact opposite problem. hahah! I don't want the mouseovers to work while the user is in the 'sub pages'. ack!

I'm trying to do it with a simple div class , but for some reason it's not switching the class name:

$(document).ready(function(){

/* here I wanted to use a div class to dictate whether this animation runs. By default, page loads with it at 'main_page' */
if ($("#testit").hasClass('main_page')) {


/* now the image animations */


var $width_one = $("#sq1").width();
var $height_one = $("#sq1").height();


$(".square.one,#link_nest").hover(function(){
    if (!$(".square.one").hasClass('animated')) {
        $(".square.one").dequeue().stop().animate({ width:"155px",height:"219px" },240);
        $("#link_nest").css({color:"#153d53",fontWeight:"400"},100);
        $("#square_caption1").css('visibility','visible');
            }
}, function() {
    $(".square.one").addClass('animated').animate({ width:$width_one, height:$height_one }, "normal", "linear", function() {
        $("#square_caption1").css('visibility','hidden');
        $("#link_nest").css({color:"black",fontFamily: "Source Sans Pro",fontWeight:"300"},100);
        $(this).removeClass('animated').dequeue();
    });
});

} else if ( $(this).hasClass('sub_page') ) { /* do nothing */

};


/* end image animations */

/* start showing,hiding */


    $('.square-container').on('click', '.square', function(event) {

/* Here, I'm trying to remove the class - i know it should probably be an 'if' statement. I'm just testing the idea */

    $('#testit').removeClass('main_page');

/* now on to the rest of the actions when clicked */

    if ( $(this).hasClass('active') ) {


            $('.details h1').animate({ opacity: 0 }, 600, function() { $('.details h1').html(' '); });
            $('.details .article').animate({ opacity: 0 }, 600, function() { $('.details .article').unload(); });
            $('.one').stop().animate({ width: '135', height: '207', left: '648', top: '190', opacity: 1}, 600, function() { /*animation completed*/ });

            $('.square').removeClass('active');
            /* this animation takes them back to the beginning, so I want to switch div back again */
            $('#testit').addClass('main_page');
