Question

I have built a site for a client and when the user clicks on a navigation link, the content of the linked page is dynamically loaded and transitioned in with JQuery, instead of loading the new page.

The problem I am having is that because it is not loading a new page, $(document).ready doesn’t fire again and any JS on the individual pages gets broken. For example, if you visit http://www.woodlandexotica.com/species.php the page works correctly, but if you try to navigate to the page from http://www.woodlandexotica.com/index_dev.php, the JS won’t work.

I’m not an expert in JS and I really appreciate any and all help!

The way you organized this code is wrong

Keep only binding’s inside document.ready and move the logic outside to a functions..which can be accessed by any page.

$(document).ready(function() {


    //////////////////////////////////////////////////
    //////////////////////////////////////////////////

    // CONTENT BG SLIDESHOW

    var photos = ["images/bg01.jpg", "images/bg02.jpg", "images/bg03.jpg"];

    var slideshowSpeed = 8000;

    var interval;   
    var activeContainer = 1;    
    var currentImg = 0;
    var navigate = function(direction) {
        currentImg++;
        if(currentImg == photos.length + 1) {
            currentImg = 1;
        }

        // Check which container we need to use
        var currentContainer = activeContainer;
        if(activeContainer == 1) {
            activeContainer = 2;
        } else {
            activeContainer = 1;
        }

        showImage(photos[currentImg - 1], currentContainer, activeContainer);       
    };

    var currentZindex = 1;
    var showImage = function(photoObject, currentContainer, activeContainer) {
        // Make sure the new container is always on the background
        currentZindex--;

        // Set the background image of the new active container
        $("#bgimg" + activeContainer).css({
            "background-image" : "url(" + photoObject + ")",
            "display" : "block",
            "z-index" : currentZindex
        });

        // Fade out the current container
        // and display the header text when animation is complete
        $("#bgimg" + currentContainer).fadeOut(function() {
            setTimeout(function() {
                animating = false;
            }, 500);
        });
        $("#bgimg" + currentContainer).css({
            "z-index" : "1"
        });
        currentZindex = 1;
    };

    function photoLoaded() {
        if(!--numPhotosLeft) {
            navigate("next");

            interval = setInterval(function() {
                navigate("next");
            }, slideshowSpeed);

            $('#bg_load').fadeOut('fast');
            $('#page_bg').animate({opacity: 1, marginLeft: '-=860'}, 500);
        }
    }

    var photos = ["images/bg01.jpg", "images/bg02.jpg", "images/bg03.jpg"];
    var numPhotosLeft = photos.length;

    for(var i = 0; i < photos.length; ++i) {
        var img = new Image();
        img.onload = photoLoaded;
        img.src = photos[i];
    }
