I am trying to ajaxify the submenus on a couple of pages for a client. I'm currently testing on a localhost site I have set up.
These are the pages of the actual site that I'm working on. The food menus on commonwealthskybar.com/menus/ and the employees section down the page on commonwealthskybar.com/about/
I found this code that I tried to alter for the food menus I'd like to ajaxify by changing the contentSelector to #guts and the $menu section to '.menuLeft,.menuRight':
// History.js It!
// v1.0.1 - 30 September, 2012
// https://gist.github.com/854622
(function(window,undefined){
// Prepare our Variables
var
History = window.History,
$ = window.jQuery,
document = window.document;
// Check to see if History.js is enabled for our Browser
if ( !History.enabled ) {
return false;
}
// Wait for Document
$(function(){
// Prepare Variables
var
/* Application Specific Variables */
contentSelector = '#guts',
$content = $(contentSelector).filter(':first'),
contentNode = $content.get(0),
$menu = $('.menuRight,.menuLeft').filter(':first'),
activeClass = 'active selected current youarehere',
activeSelector = '.active,.selected,.current,.youarehere',
menuChildrenSelector = '> li,> ul > li',
completedEventName = 'statechangecomplete',
/* Application Generic Variables */
$window = $(window),
$body = $(document.body),
rootUrl = History.getRootUrl(),
scrollOptions = {
duration: 800,
easing:'swing'
};
// Ensure Content
if ( $content.length === 0 ) {
$content = $body;
}
// Internal Helper
$.expr[':'].internal = function(obj, index, meta, stack){
// Prepare
var
$this = $(obj),
url = $this.attr('href')||'',
isInternalLink;
// Check link
isInternalLink = url.substring(0,rootUrl.length) === rootUrl || url.indexOf(':') === -1;
// Ignore or Keep
return isInternalLink;
};
// HTML Helper
var documentHtml = function(html){
// Prepare
var result = String(html)
.replace(/<\!DOCTYPE[^>]*>/i, '')
.replace(/<(html|head|body|title|meta|script)([\s\>])/gi,'<div class="document-$1"$2')
.replace(/<\/(html|head|body|title|meta|script)\>/gi,'</div>')
;
// Return
return result;
};
// Ajaxify Helper
$.fn.ajaxify = function(){
// Prepare
var $this = $(this);
// Ajaxify
$this.find('a:internal:not(.no-ajaxy)').click(function(event){
// Prepare
var
$this = $(this),
url = $this.attr('href'),
title = $this.attr('title')||null;
// Continue as normal for cmd clicks etc
if ( event.which == 2 || event.metaKey ) { return true; }
// Ajaxify this link
History.pushState(null,title,url);
event.preventDefault();
return false;
});
// Chain
return $this;
};
// Ajaxify our Internal Links
$.menuS.ajaxify();
// Hook into State Changes
$window.bind('statechange',function(){
// Prepare Variables
var
State = History.getState(),
url = State.url,
relativeUrl = url.replace(rootUrl,'');
// Set Loading
$.menuS.addClass('loading');
// Start Fade Out
// Animating to opacity to 0 still keeps the element's height intact
// Which prevents that annoying pop bang issue when loading in new content
$content.animate({opacity:0},800);
// Ajax Request the Traditional Page
$.ajax({
url: url,
success: function(data, textStatus, jqXHR){
// Prepare
var
$data = $(documentHtml(data)),
$dataBody = $data.find('.document-body:first'),
$dataContent = $dataBody.find(contentSelector).filter(':first'),
$menuChildren, contentHtml, $scripts;
// Fetch the scripts
$scripts = $dataContent.find('.document-script');
if ( $scripts.length ) {
$scripts.detach();
}
// Fetch the content
contentHtml = $dataContent.html()||$data.html();
if ( !contentHtml ) {
document.location.href = url;
return false;
}
// Update the menu
$menuChildren = $menu.find(menuChildrenSelector);
$menuChildren.filter(activeSelector).removeClass(activeClass);
$menuChildren = $menuChildren.has('a[href^="'+relativeUrl+'"],a[href^="/'+relativeUrl+'"],a[href^="'+url+'"]');
if ( $menuChildren.length === 1 ) { $menuChildren.addClass(activeClass); }
// Update the content
$content.stop(true,true);
$content.html(contentHtml).ajaxify().css('opacity',100).show(); /* you could fade in here if you'd like */
// Update the title
document.title = $data.find('.document-title:first').text();
try {
document.getElementsByTagName('title')[0].innerHTML = document.title.replace('<','<').replace('>','>').replace(' & ',' & ');
}
catch ( Exception ) { }
// Add the scripts
$scripts.each(function(){
var $script = $(this), scriptText = $script.text(), scriptNode = document.createElement('script');
scriptNode.appendChild(document.createTextNode(scriptText));
contentNode.appendChild(scriptNode);
});
// Complete the change
if ( $body.ScrollTo||false ) { $body.ScrollTo(scrollOptions); } /* http://balupton.com/projects/jquery-scrollto */
$body.removeClass('loading');
$window.trigger(completedEventName);
// Inform Google Analytics of the change
if ( typeof window._gaq !== 'undefined' ) {
window._gaq.push(['_trackPageview', relativeUrl]);
}
// Inform ReInvigorate of a state change
if ( typeof window.reinvigorate !== 'undefined' && typeof window.reinvigorate.ajax_track !== 'undefined' ) {
reinvigorate.ajax_track(url);
// ^ we use the full url here as that is what reinvigorate supports
}
},
error: function(jqXHR, textStatus, errorThrown){
document.location.href = url;
return false;
}
}); // end ajax
}); // end onStateChange
}); // end onDomLoad
})(window); // end closure
When I tested it out, it worked great on the food menus. However, it was also affecting the main menu, and I was ending up with code appearing on pages.
What changes do I need to make so that only the submenus invoke the javascript?
Any help is greatly appreciated.
