Load function between AJAX and Wordpress doesn't work - php

Question

I can't get the content from a div (width a specific ID) from single.php into index.php with ajax.
Now I have this code and returns "0".
$("body").on("click", 'a.loadcontent', function() {
var href = $(this).attr('href');
var type = $(this).data('type');
var id = $(this).data('id');
var slug = $(this).data('slug');
});
function loadcontent(type,id,slug, action) {
jQuery.ajax({
type:'POST',
url:srvars.ajaxurl,
data: {
action:'sr_get_content',
id:id,
type:type
},
success: function(response) {}
});
}
and from functions.php
add_action('wp_ajax_nopriv_sr_get_content', 'loadAjaxPosts');
add_action('wp_ajax_sr_get_content', 'loadAjaxPosts');
function loadAjaxPosts() {
switch($_REQUEST['type']) {
case 'portfolio':
$output = sf_portfolio_items($_REQUEST['cat'], $_REQUEST['count'], $_REQUEST['page'], true);
break;
case 'blog':
$output = sf_blog_items($_REQUEST['cat'], $_REQUEST['count'], $_REQUEST['page'], true);
break;
default:
$output = 'Incorrect type specified, please contact support.';
break;
}
$output=json_encode($output);
if(is_array($output)) {
print_r($output);
} else {
echo $output;
}
die;
}
How to transfer the content?
Thanks

I have that part too..
$("body").on("click", 'a.loadcontent', function() {
var href = $(this).attr('href');
var type = $(this).data('type');
var id = $(this).data('id');
var slug = $(this).data('slug');
if(window.location.hash.substr(1) == slug) {
$('html, body').animate({scrollTop: 0}, animationSpeed, $easingType);
} else {
window.location.hash = slug; // set the hash
//history.pushState({page:href}, href, href);
loadcontent(type,id,slug,false);
}
return(false);
});
