change value of a php variable on ajax content load - php

Question

I thought this would be really simple but obviously after a couple of days trial and no success I have to ask the people to help, looked everywhere.
right im basically creating a php template without much guidance on the foundation 4 framework with is a responsive framework. Now this framework is rather basic and so to add page transitions ive had to use jquery to do what i believe is an ajax call to take "content" from another page and display it on the template page index.html
for which I am currently using the following
<script>
$(document).ready(function() {
$('nav.top-bar > section.top-bar-section > ul.right > li > a').click(function() {
var toLoad = $(this).attr('href')+' #content';
$('#content').hide(1000,loadContent);
$('#load').remove();
$('#main_wrapper').append('<span id="load">LOADING...</span>');
$('#load').fadeIn('fast');
window.location.hash = $(this).attr('href').substr(0,$(this).attr('href').length-0);
function loadContent() {
$('#content').load(toLoad,showNewContent);
}
function showNewContent() {
$('#content').show(1000,hideLoader);
}
function hideLoader() {
$('#load').fadeOut('fast');
}
return false;
});
});
</script>
NOW before i changed over to using ajax and jquery i was operating the menu "active" class and the page name with a simple variable set on each page in the first line listed as $page='' and then the page name
now that im loading the content with ajax even if i include this variable in the content of the new page it will not update in either the or the menu title
im very sorry i dont write things correctly im new to this forum thing
thank you for the help in advance
:) I prefer someone to explain what i need to do and how to do it rather than just copy and pasting code as im a learner :)

Answer 1

You probably want to load the page and parse the result in jQuery to get the new page’s <title> tag and set the requesting page’s <title> tag.
The only thing I’d ask is: why are you doing this? Are you just wanting AJAX page navigation in your website instead of the traditional propagating navigation?

Answer 2

I am only able to answer one part of your question due to extreme confusion, so:
First off, here's why your url changes:
window.location.hash = $(this).attr('href').substr(0,$(this).attr('href').length-0);
You are modifying it with that line. That line, however, has an interesting little quirk:
attr('href').length-0
at the end. Why the -0? That would make no difference. I'd clean it up.
Outside of that, I'm incredibly confused with what you're asking so let me try rephrasing it and you can tell me what I'm missing.
You want to have a user click on a navigation link, and load that link's content via an AJAX call using jQuery, and then replace the content on the page with the newly loaded page, correct?
When you say "right on top main page i have variable $page = then the page name", what do you mean by "main page"? Do you mean it's a line of text in HTML? Part of a script that you haven't included here? Part of your PHP code?
And then you say "ive tried including the tag in a div that changes along with the above content"- what is "the tag"?
By reading this 4 or 5 times I could barely discern the above understanding of what you're trying to do.
Please make heavy edits to you question- it's incredibly hard to understand.
Lastly, why are you trying to replace the browser's functionality of a user clicking a link and loading content? That's what the browser is for. The browser also, conveniently, has a loading indicator in the url bar usually (or some form thereof), letting the user know the content is still loading.

Answer 3

function loadContent() {
$('#content').load(toLoad,showNewContent);
}
So first off, look at the jQuery doc for the load method:
http://api.jquery.com/load/
Your issue is that it is calling for three arguments, and you are passing two. If there are multiple arguments listed and you only want to pass SOME of them, you still need to supply a null value for the ones you want to "skip". Try changing your call to this:
function loadContent() {
$('#content').load(toLoad, null, showNewContent);
}
You'll notice that I'm passing "null". If that doesn't work, pass an empty string, like this:
function loadContent() {
$('#content').load(toLoad, "", showNewContent);
}
That second argument is data to be passed with the request. It's the THIRD argument that you list as your callback, which as far as I can tell is where you're making the mistake.
