I currently have Jquery tabs for different content on a page but this does not help me SEO wise as google and other places will not pick up this content.
I am looking for "tabs" but instead when you click on a link it loads that bit of information.
An example of this would be here http://www.gamespot.com/watch-dogs
You click on a "tab" say reviews and it loads that content along with a url of http://www.gamespot.com/watch-dogs/reviews/
I am looking to replicate something like this rather than using Jquery tabs.
Your help would be grand!
If you want the content to be picked up by search engines, it has to be in the original HTML. They won't run scripts that update the DOM on the client. So you need to do it in PHP:
<div>
<?php readfile("url"); ?>
</div>
However, if the URL is for a full web page, this is probably a bad idea. It will have its own <html>, <head>, and <body> tags, and these should appear only once on a page, not embedded inside another page.
<div id="myContent"></div>
load method:
$("#myContent").load("url to your content which you want to load", function(){
// things which you want to do with.
});
Try jQuery's load function:
$( "#element to put data in" ).load( "address", function() {
alert( "Load was performed." );
//what to do when done loading page
});
In order to make both search engines (which likely won't execute JQuery) and users (who might like dynamic elements) happy, you could do two solutions. You might have a link which when clicked goes to a brand new HTML page. Search engines will follow this link and see a whole separate page. Then, you might have a javascript within your page (or within the link's click event) that intercepts and overrides the original link's target and instead executes something like JQuery's $().load(). To reuse content you could have the target page be capable of loading both with and without a wrapper.
Target File:
<?php if(!isset($_GET['skipWrapper'])) { include('header.php'); } ?>
Here's the content that matters!
<?php if(!isset($_GET['skipWrapper'])) { include('footer.php'); } ?>
Source File:
<?php if(!isset($_GET['skipWrapper'])) { include('header.php'); } ?>
Here's the orginal content!
<a href="TargeFile.php" onclick="asyncLoad('TargeFile.php'); return false;">
<?php if(!isset($_GET['skipWrapper'])) { include('footer.php'); } ?>
Definition of asyncLoad:
function asyncLoad(url) { $('#targetElementId').load(url + '?skipWrapper=true'); }
However, it might be best to just stick with the traditional links rather than doing async tabs. Users get confused when the back button doesn't work or when common behaviors (like middle click to open a link in a new browser tab) no longer work.

The main goal is to keep non-refreshed the logotext <div class="small-7 medium-4 columns logo"> and the menu <nav class="pagedMenu" role="navigation">,without clipping on page refresh or while the content is loading from a page to another. Also, the menu state should be preserved from a page to another.
I've found here a possible solution that could solve the problem (you could use ajax to fetch the updated content and use jQuery to put the new content on the page and avoid the refresh entirely. Doing it that way, the existing data in the page would remain untouched. said #jfriend00)
So, I have tried to use an Ajax plugin (called AWS). In the AWS option page, I (suppose) that I've done the right thing pointing wrapper as Ajax container ID and also pagedMenu as Menu container class, Transition Effect Enabled, No ajax container IDs blank, no loader selected, having already a pulse loader implemented in the theme.
At this point, all I got it's a menu / side-menu (shiftnav) / pulse dot loader / content loading malfunction, generated perhaps by the wrong defined Ajax container id and/or menu container class(?) OR by a conflict with an existing JS / jQuery code, not so sure.
Also in Chrome console there is an error:
Uncaught SyntaxError: Unexpected token ;
(anonymous function) # ajaxify.js?ver=4.3.1:175
n.extend.each # jquery-2.1.4.min.js?ver=2.1.4:2
n.fn.n.each # jquery-2.1.4.min.js?ver=2.1.4:2
$.bind.$.ajax.success # ajaxify.js?ver=4.3.1:169

n.ajaxTransport.k.cors.a.crossDomain.send.b # jquery-2.1.4.min.js?ver=2.1.4:4
Everything is getting back to normal on page refresh but doesn't help at all, being useless.
I also have to mention that for the menu I've tried to keep the state using jQuery-Storage-API and storage=jQuery.sessionStorage; as you can see in mynewmenu.js file but that will not solve the non-refreshing elements problem.
The menu jsfiddle only, if this helps to have the whole picture, here thanks to #Diego Betto.
You can use this live link as example; there is a similar situation with the above described - Ajax implementation right(?) - and regarding the appearance, menu is kept non-refreshed from one page to another; if you browse Books, Works etc, menu sections you'll see; if there is a model that could be implemented here, I'll be glad to find it.
LE: meanwhile, I've tried another ajaxify solution made by #arvgta - special thanks - without success yet but as far as I've found from the Author, the defined elements should be div's with id's not classes. So, I'll try to find a way to modify somehow the code in order to have id instead on classes.
Also, I'll try to transform and implement in ajaxify.min.js file, the page-container element; jQuery('#page-container').ajaxify(); I'll come back with news.
LE2: I've tried to implement the solution using id's instead of classes but still, the pages are not loading correctly.
At this point we have ajax.min.js file updated with these lines:
(function($){
jQuery(document).ready(function(){
jQuery('#page-container').ajaxify({requestDelay:400,forms:false});
});
})(jQuery);
Also, I've modified the theme file to have id=page-container instead if class=page-container.
In these conditions, on menu click, the links are changed (like it should), menu/ logotext elements seems to working almost fine (sometimes get skippy changing position), but the content is not loading correctly in all cases; Same here, everything is getting back to normal on manual page refresh (f5), but doesn't help.
LE3: It looks like the conflict is (at least) between Revolution Slider plugin and Ajaxify.
errormessage="Revolution Slider Error: You have some jquery.js library include that comes after the revolution files js include." ;="" +=" This includes make eliminates the revolution slider libraries, and make it not work." "<="" span="">"
Site live link here. Any thoughts / alternative in this area? (not interested in using other different platforms, different WordPress themes, etc. just a workaround in this existing situation)
LE4: As far as I can see, there are many users that voted up the Jake Bown answer that could be indeed a solution; but I can't find the reason that didn't work correctly implemented into my theme (without errors) live link here The elements logotext / menu are still fading on refresh, are not kept non-refreshed. Any thoughts #Jake Bown / anyone?
LE final.
Buzinas delivered the closest answer for my needs, taking in consideration my site environment (plugins installed, etc).
From what you said I think I might have found the solution you're looking for - you want to load content dynamically whilst keeping the logo and navigation untouched? If so, this might be what you're looking for.
In the example, the pages are loaded in from a div within the page but could be used to load another URL or file:
$('.viewport ul li a').on('click', function(e) {
e.preventDefault();
var link = this.hash.substring(1, this.hash.length);
if($('.'+link).length) {
$('.viewport span.body').html($('.'+link).html());
}
});
TL;DR
I've created a plunker for you, take a look, and play with it as long as you can. You'll learn a lot from it!
I think you're trying too many things here, but didn't try the simplest:
The main goal is to keep non-refreshed the logotext and the menu ,without clipping on page refresh or while the content is loading from a page to another. Also the menu state should be preserved from a page to another.
If you want to do that, there are a few steps:
Create a 'master' page, that we're going to call index.html from now on.
So, our index must have the static part of our page, e.g menu, logo, footer etc.
Then, our 'subpages' must be cut down (no html, head, body, script, style tags, only the content that should be showed into our master page).
That done, now we must change our links to use AJAX instead of doing full refresh:
/* we add a 'click' event handler to our menu */
document.getElementById('menu-menu-2').addEventListener('click', function(e) {
var el = e.target;
/* then, we see if the element that was clicked is a anchor */
if (el.tagName === 'A') {
/* we prevent the default functionality of the anchor (i.e redirect to the page) */
e.preventDefault();
/* we show our spinner, so the user can see that something is loading */
spinner.classList.remove('hidden');
/* and we call our AJAX function, passing a function as the callback */
ajax(el.href, function(xhr) {
/* we get our main div, and we replace its HTML to the response that came
from the AJAX request */
document.getElementById('main').innerHTML = xhr.responseText;
/* since the request was finished, we hide our spinner again */
spinner.classList.add('hidden');
});
}
});
Ok, now our pages are already working via AJAX, and not reloading our static content.
But now, we see that we have some issues. For example, if someone tries to open one of our pages directly via URL, he'll see unstyled page, without the menu/logo etc. So, what should we do?
We have a few more steps now:
Simulate that our links are effectively transfering between pages using the History API:
/* inside our ajax callback, we save the fake-redirect we made into the pushState */
ajax(el.href, function(xhr) {
document.getElementById('main').innerHTML = xhr.responseText;
/* save the new html, so when the user uses the back button, we can load it again */
history.pushState({
html: main.innerHTML,
title: el.textContent + '| neuegrid'
}, '', el.href);
/* (...) */
});
/* and outside it, we add a 'popstate' event handler */
window.addEventListener('popstate', function(e) {
/* so, if we've saved the state before, we can restore it now */
if (e.state) {
document.getElementById('main').innerHTML = e.state.html;
document.title = e.state.title;
}
});
And we need that when the user enters directly to another page, e.g about-us, we redirect him to the index.html, and then load the about-us page from there.
So we create a redirect.js file, and we reference it in all of our
subpages:
/* save the page that the user tried to load into the sessionStorage */
sessionStorage.setItem('page', location.pathname);
/* and them, we redirect him to our main page */
location.replace('/');
And then, in our index.html page, we see if there is any page in the sessionStorage, and we load it, if there is, otherwise we load our home page.
var page = sessionStorage.getItem('page') || 'home';
/* we look into the menu items, and find which has an href attribute
ending with the page's URL we wanna load */
document.querySelector('#menu-menu-2 > li > a[href$="' + page + '"').click();
And that's it, we're done now. Take a look at the plunker I've been making to you.
And play with it as long as you can, so you'll learn a lot from it.
I hope I could help you! :)
Note: Just for reference, this is our ajax function:
function ajax(url, callback, method, params) {
if (!method) method = 'GET';
var xhr = new XMLHttpRequest();
xhr.open(method, url);
if (callback) xhr.addEventListener('load', function() {
callback.call(this, xhr);
});
if (params) {
params = Object.keys(params).map(function(key) {
return encodeURIComponent(key) + '=' + encodeURIComponent(params[key]);
}).join('&');
xhr.send(params);
} else {
xhr.send();
}
}
GOING AJAXED WITH WORDPRESS
demo: http://so.devilmaycode.it/how-to-keep-elements-non-refreshed/
follow these simple steps (let's take as example theme "twentyfifteen" on the WP templates folder):
edit single.php, page.php, index.php and all other pages having get_header() and get_footer() functions and replace it respectively with below code:
NOTE: this is important because if someone (ex: search-engine) reach your pages directly from the link, it is still fully available and 100% working. (useful for SEO)
<?php
//get_header()
if(!isset($_REQUEST['ajax'])){
get_header();
}
?>
<!-- other code --->
<?php
//get_footer()
if(!isset($_REQUEST['ajax'])){
get_footer();
}
?>
open the header.php add the below code inside the <head> section at the very end
<script>
!(function($) {
$(function() {
$('.menu-item a, .widget-area a, .page_item a').on('click', function(e) {
e.preventDefault();
var href = this.href;
var query = href ? (href + (!/\?/g.test(href) ? '?' : '&') + 'ajax=1') : window.location;
/* IMPLEMENT SOME LOGIG HERE BEFORE PAGE LOAD */
/* ex: kill instance of running plugins */
$('#content').hide().empty().load(query, function() {
/* IMPLEMENT SOME LOGIG HERE AFTER PAGE IS LOADED */
/* ex: refresh or run a new plugin instance for this page */
jQuery(this).show();
});
});
});
})(jQuery);
</script>
in the header.php file put the code below at the end of the file, 90% of times you need it under the navigation. In this case we already have this on the "twentyfifteen" theme.
NB: most probably you have the opening tag <div id="content" class="site-content"> inside the header.php file and the closing tag </div> on the footer.php file, this doesn't matter, you can leave it as is.
<div id="content"></div>
NOTE: consider this a proof of concept; it may work as is, but you still need to tailor it to suit your needs; you may need to:
Add a menu (in case it is not already set) by going under Appeareace > Menus > [check Primary Menu] > Save Menu in order to activate the menu. it's tested and working.
You may want to add some other class to the jQuery function like .widget-area a in order to ajax also widget links.
if you are using 3d party plugins you may need to ensure that all dependencies of each plugin are loaded also on the main page from where you want everything is displayed without refreshing content.
you may need to check and kill those 3d party plugin before a new page load and run or refresh plugin needed in the loaded page.
I've a menu and a content div. Content div is not displaying. When user clicks a menu item, content div shows and page smooth scrolls to top of the content div. Here is my code:
<div id="content">
<div id="section1">
<a id="bir" href="#icerikBaslik">1</a> <!-- This -->
<a id="iki">2</a>
<a id="uc">3</a>
<a id="dort">4</a>
</div>
</div>
<div id="icerikDiv">
<h1 id="icerikBaslik">Deneme</h1>
<p>Random content</p>
</div>
When user clicks "a id 1, (commented by This)" #icerikDiv shows and page scrolls. With this jQuery methods:
$('html, body').animate({
scrollTop: $(selector).offset().top
}, 1000);
};
$(document).on('click', '#content a', function () {
$('#icerikDiv').show();
scrollToElement($(this).attr('href'));
});
So that's it for a menu item. Question is, I don't want to lose smooth scrolling and because of that I don't want page to be refreshed.
When user clicked another link, content of #icerikDiv must be changed. Page will still scroll to #icerikDiv but content will be different. This is what I want.
And if possible, I want to keep content datas in php files. Like "menu1.php", "menu2.php" etc.
When user clicks a link, can I include related php file into #icerikDiv without refreshing page?
I thought about:
Give every link a specific method
Inside them, show #menuXcontent and scroll to #menuXcontent
Write down all content in same page, display:none;
For example when clicked menu6 link, show #menu6content and scroll to it
But I didn't like this. I'm sure there is a better way.
You have two main options. One is like you describe, to include all of the content in a single page and show it as needed. This is a viable solution which is used quite often. The advantage is that once the page loads it is very responsive, as it does not need to get data from the server when you click a link. The disadvantage is that the initial page load will be much bigger. It would generally work well for sites where the individual sections were quite small.
The second option is to use ajax to get your content from the server without a page reload. Ajax can be used to get data or html from your server. If you have a php file which gives the output you want in html, you can use the .load convenience method:
$( "#icerikDiv" ).load( "menu1.php" );
This will get the data from menu1.php and put it in to #icerikDiv.
To avoid hardcoding the php file, we can use a data attribute so that the source is declared on each link -
HTML:
<a id="bir" href="#icerikBaslik" data-content="menu-1.php">1</a>
Javascript:
$(document).ready(function() {
$('#content a').click(function () {
$( "#icerikDiv" ).load( $(this).data('content') );
$('#icerikDiv').show();
scrollToElement($(this).attr('href'));
});
});
It might make more sense to put the div target on the data attribute and use href for the source php - but it will work either way.
You can load content from a php file via ajax calls and append it to anywhere you want on the page using javascript.
Read up on ajax:
http://www.w3schools.com/ajax/
http://api.jquery.com/jquery.ajax/
A simple example would be:
$("#loadcontent").on("click", function(e){
$.ajax({
type: "get",
url: "loadcontent.php",
success: function(content){
$("#contentdiv").html(content);
}
});
});
This would change the content of #contentdiv into whatever is echoed from loadcontent.php.
I am building my website and in the main PHP page, I got something like this:
...
<a class="aboutMe" href="?section=aboutMe"></a>
<a class="network" href="?section=network"></a>
<a class="map" href="?section=map"></a>
...
If someone click any of the links above, the in the same page, the PHP will do this:
<?php
if(array_key_exists ("section", $_REQUEST)) {
if($_REQUEST["section"] == "aboutMe") {
include(app_path().'/views/about-me.blade.php');
}
else if($_REQUEST["section"] == "network") {
include(app_path().'/views/network/index.php');
}
else if($_REQUEST["section"] == "map") {
include(app_path().'/views/my-trace.php');
}
}
?>
After the sub page is road, it is placed right under the main page, and I would like to make it automatically scroll down to the joint part so the user could see the sub page immediately, something like this:
<main page>
<- scroll to here
<sub page>
It sounds not difficult, and I've already written some jQuery to do this job. However the whole page was refreshed after the including, and the jQuery is run before the fresh. How could I fix that?
Or is that possible to include sub pages without refresh the whole page? This would be a preferred solution. Many thanks in advance!
PHP runs on the server. It sends a response to the user's browser, then javascript runs in the browser. If you want to execute more PHP code after the response has been sent, the user has to send another request to the server and get a new response. You can do this without reloading the page using ajax: http://learn.jquery.com/ajax/
Alternatively, if there are only the three different pages, you could just include the html code for all three pages in the initial response. Then just use javascript to change what is visible.
I am new to Jquery mobile.
I am trying to get Sliding effect when i navigate to another page say # display2 from thie below code.
but i am not able to get slide effect.
If I remove the rel="external" i am able to slide but on the #display2(page whihc i would navigate to),the query string values are returned as null.
so if i put rel="external" the parameters are passed to #display2 but slide transition not working.
if i remove re="external" slide works but the querystring parameters are returned null.
can you please let me know is there a way where both of them work together.
('#display').on('pagebeforeshow', function () {
// $(this).find('[data-role=header] .ui-title').text(json.getLOBXMLResult[currentItem].FolderName);
$.ajax("AppstoreWS.svc/getLOBXML", {
beforeSend: function (xhr) {
$.mobile.showPageLoadingMsg();
},
complete: function () {
$.mobile.hidePageLoadingMsg();
},
contentType: 'application/json',
dataType: 'json',
type: 'GET',
error: function () {
//alert('Something awful happened');
},
success: function (data) {
result1 = data.getLOBXMLResult;
$('#categoryList').children().remove('li');
$.each(result1, function (index, output) {
$('#categoryList').append('<li>' + output.FolderName + '</li>');
});
$('#categoryList').listview('refresh');
}
});
});
Part 1 - why rel=external worked & other options
The reason why rel=external works with no transition is because this expects the browser to open an external page and therefore, disable ajax. To counter-effect this, you've got numerous options :
By using Single page template
You could make your two pages into a single page. This is called a single page template and your second page's reference would be #page2 (or any name you'd give as the ID). This is how it'd look like :
<div data-role="page" id="page1">
<!--Stuff in page 1-->
</div>
<div data-role="page" id="page2">
<!--page 2 stuff-->
</div>
Advantages
The DOM can leverage the power of ajax driven navigation.
This would make partial loading, script loading easy, as you'll need to refer all this only once.
Data-transfer between pages is very simple. You'll just have to store the data in you need in a global variable or in the data property of the #page2, and retrieve it in the pageinit or pageshow (or any event) of the second page.
Transitions, etc will work.
There will be no page refresh.
Disadvantages
If the HTML content of the two pages are large, it'll be difficult for maintenance.
By using rel=external
As you might have seen, rel=external can be used only when a page refresh is absolutely needed. Its upto the user's choice. If an a tag is marked with rel=external it means the browser will treat it as an external link, and will ignore jQuery Mobile's ajax navigation system.
By referring all the scripts of page 2 in page 1
Generally, to be able to use page transitions, you must use ajax system of navigation in jQM. So the general behaviour of ajax is as follows :
page1 will request for page2 in page2.html.
The <body> of page2.html alone is taken from page2.html.
The <head> section( which might contain your scripts, which might have your query-string logic) will be ignored.
So to change this, you can refer to page2's scripts in page1.html's head so that these scripts will be loaded and ready when jQM's ajax system pulls the body of page2.html.
<script src="jqm.js"></script>
<script src="page1.js"></script>
<!--page 2 scripts-->
<script src="page2.js"></script>
Advantages
Your transitions will be working properly.
The common scripts will not be referred to multiple times, hence much faster loading times.
Query strings will also work
Disadvantages
If the two pages have very little in common, you'll end up having unwanted scripts in your first page.
What if you have more than two pages? What if you have 10 pages? Will you refer to all 10 pages' scripts in page1. I dont think thats the way.
By referring to page2 scripts inside "data-role=page" section of page2.html (recommended)
This will bring the scripts along with the page when ajax brings it in. This will also work with query strings. This will look something like this :
<div data-role="page" id="page2">
<script src="page2.js"></script>
<!--- your html-->
</div>
Advantages
The scripts pertaining to a particular page are restricted to within that page.
Transitions will work.
Query strings will also work
Part 2 - alternative to query string
The reason I'm saying this because Query strings are archaic technology, because at that time, there was no way to store to data. They're also insecure because user can see the data you send over the URL. You must consider using something like localStorage. I'm not saying you must NOT use query strings. It's just that there are better options available for mobile data storage. See this link for more info about how you can use this localStorage. Also, see this for all the options you have. Now, looking at your query string :
platform=' + output.FolderName + '&sid=test
This could easily be made into an object. So in the click function of the anchor tag inside <li>,
$(document).on("click", "li a", function(e) {
//stop default action.
e.preventDefault();
//take the href; Im assuming its page2.html?platform=outputFolder&sid=test
var params = this.href.split("?");
//now params[0] = page2.html
//param[1] = platform=outputFolder&sid=test
//set this in localStorage
localStorage["page2params"] = param[1];
//change to page2.html
$.mobile.changePage("page2.html", { transition : slide });
})
Then, in the page2.html's pageinit method, you could retrieve it for your use :
//assuming you have a page with page2 as id in page2.html
$(document).on("pageinit", "#page2", function() {
var params = localStorage["page2params"];
//do anything you want with params.
});
I'm sure I'm missing something pretty basic, but I have just started to get myself up to speed on jQuery and Javascript programming. Previously I was doing server side programming with PHP.
I'm now in the middle of creating a prototype for HTML5 webapp, where I would like to have different screens. Now with PHP that was pretty easy, I could just used server side templates like Smarty and be done with it.
However to make my app more webapp like, I would like to dynamically change between screens without having to reload the window.
I have looked into several options that might be anwsers to my question, but I'm not sure whether I'm on the right track.
I have checked for example JsRender, JsViews or even the pure jquery load command.
But what I'm not sure is whether these things would allow me to have something like this:
HEADER_PART
MAIN_CONTENT
FOOTER_PART (also contains links to common JS files that I use)
I would like to dynamically update the MAIN_CONTENT part. Currently my application is only one page, and all my custom logic that belongs to that page is in one JS file. In this JS file, I use a simple $(function() { ... to load my page, so whenever it gets loaded, parts of my page get updated asyncronously. This is fine, since all my blocks in this certain page would have to be loaded when that one page gets loaded.
But what if I have a link, like main.html#otherscreen, and when I click that screen, I would like to change my MAIN_CONTENT and also run another page load specific JS that handles blocks on that other screen, not the first page?
I know I could still use probably server side templating and load my pages using AJAX requrests, but again, not sure whether that is the right approach.
Could you please enlighten me? :)
Thanks & best regards,
Bence
Check out jQuery.load(). Using this function you can dynamically load content into a div on the page, which is what I think you want to do. Just find the div on the page you want to load content into and call
$('#mydiv').load(url, data, function(response){
//do something once it's done.
});
Per your comments...
This is actually very easy. .load() should replace the content in the div (I think. If not, just call .empty() first). Of course you could get fancy and add effects, like
function changePages(url) {
$('#mydiv').fadeOut('fast', function() {
$(this).load(url, function(response){
$('#mydiv').fadeIn('fast');
});
});
}
To handle things like the hash in the URL, in your click event you have to make sure you first call e.preventDefault():
$('#mylink').click(function(e){
e.preventDefault(); //e is a jquery event object
var link = $(this);
var hash = link.attr('href'); // get the hashtag if the href is '#something'
changePages(someUrl + hash);
});
For dynamic loading of data into the page without changing your header and footer you should use jQuery's AJAX function. It allows you to post requests to the server and receive data back without reloading the page. A simple example would be something like:
<html>
<head>
<title>Example</title>
<!-- Assuming jQuery is already referenced -->
<script type="text/javascript">
$('span.buttonish').click(function(){
$.ajax({
// The URL can be a file or a PHP script of your choosing
// it can also be pure HTML without the <html> tags as they
// are already in your file
url: 'path/to/the/file/that/return/data',
success: function(receivedData) {
// The received data is the content of the file or the return
// data of the script and you can use it as you would with any data
$('#content').html(receivedData);
}
});
});
</script>
</head>
<body>
<div id="header">
<!-- Something -->
</div>
<div id="content">
