reinitialize other javascript functions after loading a page with ajax pagination

Question

Apologies, a total newb here. How can I load other plugins, and let other separate scripts function after loading an ajax generated page? This is my curent code:

jQuery(document).ready(function($) {
var $mainContent = $("load-content"),
siteUrl = "http://" + top.location.host.toString(),
url = ''; 

$(document).delegate("a[href^='"+siteUrl+"']:not([href*='/wp-admin/']):not([href*='/wp-login.php']):not([href$='/feed/'])", "click", function() {

if($.browser.msie){
var myie="/"+this.pathname;
location.hash = myie;
//alert(location.hash);

}else{

location.hash = this.pathname;
}
return false;
});


$("#searchform").submit(function(e) {

$search = $("#s").val();
$search = $.trim($search);
$search = $search.replace(/\s+/g,'+');

location.hash = '?s='+$search;
e.preventDefault();
});

$(window).bind('hashchange', function(){
url = window.location.hash.substring(1);
if (!url) {
return;
}

url = url + " #content";

$('html, body, document').animate({scrollTop:0}, 'fast');

$mainContent.fadeOut(500, function(){$('#content').fadeOut(500, function(){
$("#loader").show();});}).load(url, function() {
$mainContent.fadeIn(500, function(){
$("#loader").hide(function(){ $('#content').fadeIn(500);});});});
});
$(window).trigger('hashchange');


});

How can embedded objects on pages retain their functionality? Mainly videos, slideshows and other media that use javascript like

video js (html5 video player)

vimeo

and

portfolio slideshow for wordpress

When you load ajax-generated markup it will not retain the functionality it had before. In your example above, you're initialising things when the DOM is ready to be acted upon. In order to make sure any plugins, etc, are running after you perform the ajax request you need to reinitialise them.

Given your code sample above, I'd recommend a little restructuring. For example, you could create a function called init which you could call to initialise certain plugins:

function init () {
    $("#plugin-element").pluginName();
}

jQuery(document).ready(function () {
    // Initialise the plugin when the DOM is ready to be acted upon
    init();
});

And then following this, on the success callback of you ajax request, you can call it again which will reinitialise the plugins:

// inside jQuery(document).ready(...)
$.ajax({
    type: 'GET',
    url: 'page-to-request.html',
    success: function (data, textStatus, jqXHR) {
        // Do something with your requested markup (data)
        $('#ajax-target').html(data);            

        // Reinitialise plugins:
        init();
    },
    error: function (jqXHR, textStatus, errorThrown) {
        // Callback for when the request fails
    }
});
