jQuery(document).ready(function(){
hideContent = function(contentString){
jQuery("div.dynamicContent").fadeOut( 1000 ,function() {
showContent(contentString);playSound(0);
});
};
if (contentString.indexOf("http") != -1)
{
location.href=contentString;
return true;
}
showContent = function (contentString) {
jQuery.ajax({
type: "GET",
url: contentString,
dataType:"html",
success: function(data){
jQuery("div.dynamicContent").html(data);
jQuery("div.dynamicContent").slideDown(1000);
},

alert("Page "+contentString+" not found");
