I see many websites such as gitHub changing it's html content and URL without refreshing pages.
I find one possible way to do this in HTML Histroy API.
Here is the code.
HTML
<div class="container">
<div class="row">
<ul class="nav navbar-nav">
<li>Home</li>
<li>About</li>
<li>Contact</li>
</ul>
</div>
<div class="row">
<div class="col-md-6">
<div class="well">
Click on Links above to see history API usage using <code>pushState</code> method.
</div>
</div>
<div class="row">
<div class="jumbotron" id="contentHolder">
<h1>Home!</h1>
<p>Lorem Ipsum is simply dummy text of the printing and typesetting industry.</p>
</div>
</div>
</div>
</div>
home.html
This is home page
about.html
This is about page
contact.html
That one is content page
JAVASCRIPT
<script type="text/javascript">
jQuery('document').ready(function(){
jQuery('.historyAPI').on('click', function(e){
e.preventDefault();
var href = $(this).attr('href');
// Getting Content
getContent(href, true);
jQuery('.historyAPI').removeClass('active');
$(this).addClass('active');
});
});
// Adding popstate event listener to handle browser back button
window.addEventListener("popstate", function(e) {
// Get State value using e.state
getContent(location.pathname, false);
});
function getContent(url, addEntry) {
$.get(url)
.done(function( data ) {
// Updating Content on Page
$('#contentHolder').html(data);
if(addEntry == true) {
// Add History Entry using pushState
history.pushState(null, null, url);
}
});
}
</script>
This code is working fine even you go back or forward in browser.
But the problem is that when you refresh page it only shows the file which is being refreshed. For example, if you refresh the about.html then only the following will show: This is the about page.
Unlike the gitHub it can't show the complete page. As you see in gitHub, even you refresh a page it will show the page same as how it was before refreshing.
How can I do that?
Thanks...
You may use Routie or Director to do the routing. And within their callback functions write the code to update the part of your HTML page, for this you may use Fragment.js.
You can change DOM anytime you want without loading the page.
Use fundamental XMLHTTPRequest or Ajax to contact the server without refreshing the browser.
There are many frameworks which offer convenient url routing which can change content automatically without page refreshes. Angular JS is my favorite such framework which offers great routing capability among many other things.
You have to check/set the value of your variable on the event onload of the page.
Your code does not work - when you click on a particular link the page does refresh. correct me if i am wrong.

I am trying to on the click of a link display a different page inside a box using jquery (.load). I'm new to programming and web design so please make answers as simple as possible.
Here is my index.html code
<nav id="navBar">
Home
About
Contact
Shop
</nav>
<div id="loadZone"></div>
and my JavaScript
$(document).ready(function(){
$("#loadZone").load("homeLoad.html");
});
function homeLoad() {
$('#loadZone').load('homeLoad.html');
}
function aboutLoad() {
$('#loadZone').load('aboutLoad.html');
}
loading the home page (homeLoad.html) works fine
when I repeatedly spam the link for about you can occasionally see the content of aboutLoad.html
Any help appreciated
Thanks
A simpler method might be to store the urls as data attributes on the links, then when the user clicks a link get the stored url and load it. To load the initial content, trigger a click on it's link on load. Something like this would work:
Here is a working Demo
<nav id="navBar">
Home
About
Contact
Shop
</nav>
<div id="loadZone"></div>
<script>
$(document).ready(function(){
$('.navLink').click(function(e){
e.preventDefault;
$('#loadZone').load($(this).data('url'));
});
$('.navLink:eq(0)').click();
});
</script>
I currently have a modal that deletes an item from my list of data. After selecting delete, I want to refresh the web page. At this point, it is refreshing the entire page and re-directing me to the Searches tab. I want to refresh just the Lists tab. How can I do this?
My HTML:
<div class="row zero-margin">
<div class="col-xs-12">
<div id="tabstrip">
<ul id="tab-strip-options">
<li id="listItem1" class="k-state-active">
Searches
</li>
<li id="listItem2">
Lists
</li>
</ul>
<div class="saved-search-content">
<div id="gridSearch"></div>
</div>
<div class="saved-list-content">
<div id="gridList"></div>
</div>
</div>
</div>
</div>
My JavaScript Function:
function deleteItemsFromList(data) {
if(data.IsSuccess) {
window.location.reload();
CloseModal("deleteSearchListModal");
showSuccessMessage('List was successfully deleted!');
}
}
Solution for server side data store:
The easiest solution for partial update on your web page is to use AJAX requests. You must load list content from web source, when you update it.
$( "#gridList" ).load( "ajax/getListContent" );
Of course your ajax/getListContent must generate proper HTML substructure (without html, body tags) like:
<div>...</div>
Generally create a data source on address ajax/getListContent which return you your data structured in HTML, then in your code you can do like this:
function deleteItemsFromList(data) {
if(data.IsSuccess) {
$( "#gridList" ).load( "ajax/getListContent", function() {
CloseModal("deleteSearchListModal");
showSuccessMessage('List was successfully deleted!');
}
}
}
I completely ignore if you are using some kind of plugin, but if you want to refresh just part of the whole HTML document, you have to use AJAX and remove the window.location.reload() from your script. Something like this:
function deleteItemsFromList(data) {
if(data.IsSuccess) {
$.ajax(/*params here*/).done(function(data){
//refresh just the #gridList part
CloseModal("deleteSearchListModal");
showSuccessMessage('List was successfully deleted!');
}
}
}
Maybe this is not the correct order, but the important thing is AJAX :)
This is the first page where I try to open the detail.html;
<a href="detail.html" data-role="none" role="link">
<div class="place">name</div>
<div class="arrow"></div>
<div class="ammount">-€4,<span class="fontsize14">25</span></div>
</a>
I have problems to load the scripts on detail.html (after href link is clicked on first page)
Here is my script in header of details.html(the page I go after href is clicked on first page), Problem is I can NOT get the console test print, that function is NOT called when details.html page is loaded. It only hits after I manually refresh the page
<script>
$(document).bind("pageinit", function(){//or $(document).ready(function ()
console.log('test');
});
</script>
To understand your problem I think you need to first understand how jQuery Mobile "loads" external pages. By default when you click a link to a separate HTML page JQM loads the first data-role="page" on that page and attaches it to the DOM of the first page, the thing is JQM only loads that page div and not any scripts etc. that are outside that container.
If you want to run code for a second page, you either need to include that script on your first page and use event delegation (since the second page is not part of the DOM yet) or include the script withing the second page's date-role="page" wrapper.
Case in point in your case if you want to run code for your details page you either need to include the script on your first page for example assuming you have a div on your detail.html page like the following
<div id="details" data-role="page"> ..rest of your content
</div>
Then on your first page you could do the following
$(document).on('pageinit', '#details', function() {
console.log('test');
});
Or alternatively you can include a script tag withing your "details" page wrapper.
EDIT:
As I mentioned this is the default behavior, however if you wish you can tell jQuery Mobile to do a full post when loading a second page by adding in data-ajax="false" or rel="external" to your link for example
<a href="detail.html" data-ajax="false" data-role="none" role="link">
<div class="place">name</div>
<div class="arrow"></div>
<div class="ammount">-€4,<span class="fontsize14">25</span></div>
</a>
The difference between data-rel="external" and data-ajax="false" is if the second page is basically semantic in that data-rel="external" should be used if the second page is on a different domain.
I made you an working example: http://jsfiddle.net/Gajotres/Eqzd2/
$("#second").live('pagebeforeshow', function () {
console.log('This will only execute on second page!');
});
You can use on instead of live if you are using last version of jQuery.
Also take a look at my article about event flow in jQM page transition: https://stackoverflow.com/a/14010308/1848600
I am playing around with djax when I click an anchor tag the url changes and when I view the page source it also changes but the page itself did not change its contents even if I view the page source it has change up any ideas why?
Here's a snippet of the markup
<body>
<div id="resultContent" class='updatable'></div>
<ul>
<li><a id="thankyou" href="views/thankyou.jsp?menuId=2"
targets="resultContent">Thank You Message</a></li>
</ul>
</body>
When I click that the url changes but the result is not showing but when I view the page source it displays the proper markup(or should I say the markup of thankyou.jsp)
here is the code that Is js code
jQuery(document).ready(function($) {
$('body').djax('.updatable');
});
I've had the exact same problem as you and discovered your question while I was looking for an answer. It may be too late for you but according to your markup I believe you ran into the same problem as me which is actually on the issue-list of the plugins Github site (at least right now).
You need to place your updateable div inside a wrapping div. For some reason exchanging content seems not to work for direct children of body. See https://github.com/beezee/djax/issues/22
So your HTML should look like this
<body>
<div id="djaxWrap>
<div id="resultContent" class='updatable'></div>
<ul>
<li><a id="thankyou" href="views/thankyou.jsp?menuId=2"
targets="resultContent">Thank You Message</a></li>
</ul>
</div>
</body>
While jQuery remains the same
jQuery(document).ready(function($) {
$('body').djax('.updatable');
});
We have a single page application with two views (essentially, a list of items and a details page for the selected item). Both views are in separate html files, and we’re using sammy.js to transition/navigate between the pages. Everything was working great until we tried to add jQuery Mobile to the mix. Now, when we navigate to the second page (the details page), jQuery Mobile is not styling the page.
Our working app is not set up as described by jQuery Mobile’s multi-page template (i.e., having all page divs in the same html file and use their navigation system to load linked pages into the DOM via AJAX). But, is it possible to have separate pages, use something other than jQuery Mobile’s navigation, and still have jQuery Mobile style the second page? Or, is there a way to force jQuery Mobile to style the second page?
Here’s some code snippets that’ll hopefully help show what we’re doing. (Note: We’re also using ASP.NET razor views.)
index.cshtml
<body>
#RenderPage("Views/items.cshtml")
#RenderPage("Views/item.cshtml")
#Scripts.Render("~/bundles/jquery")
<script>
$(document).bind("mobileinit", function () {
$.mobile.ajaxEnabled = false;
$.mobile.hashListeningEnabled = false;
$.mobile.pushStateEnabled = false;
$.mobile.loader.prototype.options.text = "loading. please wait...";
$.mobile.loader.prototype.options.textVisible = true;
});
</script>
#Scripts.Render("~/bundles/jquerymobile", ...)
</body>
items.cshtml (this page gets loaded and rendered correctly)
<section id="items-view" class="view" data-role="page">
<section data-role="header">
....
</section>
<section data-role="content">
(navbars, ULs, LIs, etc. are here, with each LI a link to go to the details page)
</section>
<section data-role="footer">
....
</section>
</section>
item.cshtml (this page gets loaded but NOT rendered correctly, there is no jQuery Mobile styling)
<section id="item-view" class="view" data-role="page">
<section data-role="header">
....
</section>
<section data-role="content">
(ULs, LIs, listboxes, textboxes, etc. are here)
</section>
<section data-role="footer">
....
</section>
</section>
router.js (used to route between pages)
....
navigateTo = function (url) {
sammy.setLocation(url); // url = #/items or #/item/1234
},
....
In the js file for the item page, we’ve tried:
var $page = $("#item-view");
//$page.trigger("create");
//$page.listview("refresh");
//$page.page(); (this one kind of work but doesn’t style every object)
//$page.page("refresh", true);
but haven’t got any thing to work correctly and completely.
So, again, given our situation, is there a way to have a jQuery Mobile multi-page app with actual separate physical files and have all pages get style correctly? Or is there a programmatic way to force jQuery Mobile to style all pages correctly?
Thanks.
jquery mobile does NOT load everything from your second page.
when you require a new page with JQM (or it's ajax method), it loads parts of your page's DOMs and get all things under
<div data-role="page" id="yourPageID"></div>
so your could simply try put your stylesheet under "data-role", like this:
<div data-role="page" id="yourPageID">
<link rel="stylesheet" href="yourStyleSheetLink.css" />
</div>
then, when JQM requires a new page, your stylesheets will be loaded.
as a non-English speaker, i hope you can understand my words :)
