What is the preferred way to navigate between HTML5 web pages without using any server side scripting language. Would Jquery be a good choice?
Consider a user logs in and lands at home page. Home page contains many links to navigate to other pages.
Edit 1
I need to communicate to server via AJAX to perform some operations and pass on variables and data between web pages. But I cannot use JSP or PHP to create HTML dynamically.
HTML
<nav>
Index
Contact
</nav>
<section id="content"></section>
jQuery
$(function(){
$('nav a').on('click', function(e) {
var htmlFile = $(this).attr('href');
e.preventDefault();
$('#content').load(htmlFile);
});
});
for link to your different pages in HTML5 you use this code.
link 1
link 1
link 1
I would say anchor tags are the best choice to do this because of their universal and flexible DOM use:
Page 1
Page 2
Page 3
If users will be logging in then you will have to use a scripting language such as PHP and establish database connections with MySQL.
jQuery has a very easy to use AJAX implementation.
It sounds like you're wanting to create a single page application that gets it's data from a third party service?
I would recommend Sammy.js for intercepting routes, and jQuery to do your actual ajax calling.
If you're doing a lot of dynamic content dynamic content I would also recommend Knockout.js
Great for use will be:
Page 1
Page 2
Page 3
It's more faster than using this:
Page 1
Of course, you'll need to have html subpages (page1...) in the same folder as your index.html.

I have created a widget.html page with, for example, a "Powered by Example.com" box/widget. And I have an HTML iframe that links to that specific page (widget.html) on my site.
<iframe src="http://example.com/widget.html"></iframe>
I share that iframe code with website owners who want to use my widget on their sites.
I want to be able to see every single site that uses my iframe. I would prefer a code that creates a txt file or even a MySQL Table with all websites URLs that use my widget on their websites.
I basically want to track the sites that use my widget as an iframe . How do I do that? With Javascript? PHP? MySQL?
P.S. I'm not sure if an iframe is the best way to link widgets off my site, but I'm open for your suggestions. Thanks in advance.
use jquery
then load a request page throgh jquery like : $("#div1").load("demo_test.txt");
and send a request uri parameter to it
you will find the current url using the widget and alos you can get the parameter
We built a website with different pages, and some of these pages have features that other pages don't have. Eg: The galleries page uses jQuery Colorbox for opening photos. So, some pages load some jQuery plugins, and some other pages don't (the 'About Us' page don't need a Colorbox plugin).
Now, the client asked us to put a persistent audio player at the top of the page. We have two alternatives: using frames (too bad!) or using ajax calls to update content and the History API to update the url/browser history.
Ok, we attached the click event to links. The event requests the new page using ajax, and then the page content is replaced. The problem is: and the js files/jQuery plugins? When the requested page's js files are loaded, the $(document).ready(); event was already fired.
Also, some pages may contain non-external javascript, like
<script type="text/javascript">
...some code here...
</script>
Any hints on how to do it the best way?
Thanks!
The external JS files should be loaded once in the parent file, so that all the dependencies are satisfied when the ajax success callback fires.
Ex:
$.get('/someUrl',function(newHtml){
//process the newly fetched html
$("#someParent").html(newHtml);
//apply whatever JQuery plugins you need at this point.
});
I have an android app where I want to show a page to users inside the webview but the problem I am facing is that I can't use the web page as it is because the page is not responsive to mobile devices and user needs to scroll horizontally and vertically a lot. The web page is:
http://www.ielts.org/test_centre_search/search_results.aspx
I just need the drop down search functionality from that page. I tried copying the html source code on my local to replicate the page but the since the html form's action has to be http://www.ielts.org/test_centre_search/search_results.aspx for fetching the results, when I select an option on my local version, it goes to the http://www.ielts.org/test_centre_search/search_results.aspx url and displays their version of page next time.
I came across this page:
http://www.ieltsessentials.com/test_centre_search.aspx
which is implementing the same functionality. How can I replicate the same and add it inside local .html document
i think the easiest way to implement this will be to inject your own css style into their html, and hide/restyle the elements that are not responsive. that way you don't have to analyze any of the logic that they have, as it will be safely on css level.
the only thing you have to figure out is how to re-inject your css into the web view after the page is reloaded. there's actually a way to do that by simply injecting a javascript call into their page like here https://stackoverflow.com/a/5010864/467198
to detect that page is reloaded i think you can use onPageFinished
you could use asp to proxy the page you want to canibalize and then in jQuery you could traverse that proxy'ed page and pull out the pieces you want to use and then create your new, responsive doc from items scraped from the original page.
i'm not an asp.net developer so i've used php in my example. here's a link to an example of how asp.net could be used to proxy a page
Simplest Possible ASP .NET AJAX Proxy Page
<?php echo file_get_contents( $_GET['u'] );
then in jQuery use $.ajax() to read the proxy'ed page as HTML and scrape the page as needed
<script>
$(function(){
$.ajax({
url:'proxy.php?u=http://www.ielts.org/test_centre_search/search_results.aspx',
dataType:'html',
success:function(data){
console.log($('#header',data));
}
})
});
</script>
in this example i'm just reading the contents of the #head but you could scrape whatever you need from the original page and then inserting them into your target dom or pass them to a template. to get what you're looking for you'd use '#Template_TestCentreSearch1_SearchTable' where i use '#head' to retrieve your drop down markup
I've noticed many websites (like Hulu.com), have very interesting page transitions. They manage to fade out of a page and into a new one.
How would this be accomplished with jQuery/Javascript. Would I somehow have to link a .js to both web pages? How would I do this?
You could do this with a combination of PushState part of the History API (pjax is an excellent way to add this to an existing site) and jQuery. This is how github handles it (try browsing folders of source code, and look at the URLs). What pjax lets you do is intercept any <a> click before the page redirects, fetch the page that would load via ajax, insert the HTML in your page (which you can control with jQuery animations like fadeIn()) and the update the browser URL so the page can be bookmarked.
No need for a .js reference on both pages, just the page before.
There are many plugins for jQuery that support most transitions.
This looks like a pretty comprehensive list, although 2010 dated.

I am using backbone.js and building a single page application, inspired by trello.com ..
I want to know how you show many pages on top of the original page. As in how you architect it.
How do you use Backbone routers to achieve this?
For example in trello
Basepage
And then now on top of the base page you have dynamic content
like a cards detail
like a boards details
How could i architecture something like this?
I've done a couple of approaches so far in projects with 50+ pages and they both scaled well. I did not use backbone.js but the approaches are straight forward and do not require a framework to learn other than I used jQuery for selectors.
Both of them have in common creating a single overlay window that you can pull in content into the window. I wrote mine from scratch but you could easily use jQuery UI dialog. The two approaches only differ in how the content is pulled. Also, using the information on the link is all you should need to pull in the "module" or overlay content as your rule. Do not need tons of scripts loaded in to start your app. Have the modules pull in the behavior for you.
Option 1) Use the jQuery load method to pull content from stand-alone web pages by using a placeholder variable like so:
var $ph = $('<div />');
$ph.load(URL); // loads gui of remote URL + executes any script that URL has
The $ph var now contains all the GUI loaded in from the external URL so you can use selector on it to extract the particular HTML and place it into your DOM or overlay as you need.
Here is an example of the stand-alone HTML output:
<div class="module">
<a class="link">click me</a>
</div>
<script>
(function(){
// put any private vars here
$('.module .link').click(function(){
// do something
});
})();
</script>
If you remove() or destroy the dom inside the overlay through jQuery, it will automatically remove all the events directly assigned aka "bind" and "unbind" them but using "live" or "delegate" you will need to worry about "die" and "undelegate" etc. just doing die('.namespace').live('click.namespace') will ensure is cleaned.
Here is an example of this on one of my websites -> http://www.kitgui.com/docs
But the better example is within the customer section as the docs is fairly simple using hash history.
2) Using an iframe inside your overlay and assigning it a URL.
This is the easiest option but is a little slower because each page called has to have a full standalone behavior and dependencies with the iframe. Also you must worry about sizing the frame etc. unless you have a fixed overlay window.
You must have a loader overlay your iframe while its loading then have the iframe talk the parent to tell it its done loading and hide the loader.
I did this for several sites but one of them is a site in development you can see here to get the code ->
http://dev.zipstory.com (sign in and go to my zipstory and click "group" settings etc to see this, just view source to see how I did this as its all there)
The thing about iframes is you should write some code on the parent that accepts standard messages from the iframe that you agree on as a typical set of behavior such as notifying its done loading or passing messages to update something on the parent etc. This can be added on the fly and refactored as you need as long as your aim is KISS approach.
Each of the 'dynamic content' pages should be a template (underscore.js gives you _.template()) rendered by a backbone view. The main page needs to have events that initialize new views and render the templates. Look at the todos app (http://documentcloud.github.com/backbone/docs/todos.html) to get a basic idea about the flow of a backbone app.
