How to get the raw markup from a jquery mobile pageload request? - ajax

How can you get the raw HTML markup from an AJAX request that loads a page in jquery mobile?
My page has a menu outside of the page container element (data-role="page") and I need to update it on each page load but jquery-mobile only gives me the page markup from the request not the entire document.
I've even tried using the global ajaxSuccess callback for jquery; apparently jquery-mobile feels the need to filter this to just the page element also.

Can't you just assign an id to the menu page and access it directly?
$('#myMenu').html(newContent);

Found the http request object in the pageload event.
$(document).bind("pageload", function (e, data) {
console.log(data.xhr.responseText);
});

Reload javascript after thymeleaf fragment render

I have javascript files defined in the <head> of both my layout decorator template and my individual pages which are decorated. When I update a thymeleaf fragment in one of my pages the javascript defined in the head of the parent page no longer works. Is there a standard way to 'refresh' these js files?
Thanks.
Additional clarification :
I have a form submitted by an ajax call which updates a table in the page. I have a Jquery onClick function targeting a button in the updated table. The javascript doesn't seem able to bind to the returned elements in the updated part of the page. I select by element class and can see that the selection works prior to the partial fragment render.
For me it is unclear what you mean by
javascript defined in the head of the parent page no longer works.
The page is created on the server. Normally it contains urls of the javascript files
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
In this case 'refreshing' the javascript files can happen only in the client.
Check the html of the page in the client.
Are the tags as expected ?
Are there tags for all expected javascript files ?
With the browser tools (for example Google Chrom developer tools ) check that all script files are actually loaded.
If this doesnt help, it could be that the order of the script tags has changed between the first and second load. This could cause a different behaviour of the javascript executed in the browser.
EDIT :
With the initial load you bind javascript callbacks to dom elements.
You do this directly or through Jquery or other libraries.
When a new dom element is loaded, it has no callbacks bound to it, even if it has the same id as a replaced dom element.
So after the load you have to bind your callbacks again.
If you bound them 'by hand', just bind it again.
If you are using a JQuery plugin, that made the bindings, look into the code or documentation, many of them have a function for that or you can call initialization again.
Once you added new content to the DOM you need to bind again the new content.
Let's say I have a button with some class, the event in binded to the class:
<button class="someclass">Button 1</button>
<script>
var something = function() {
// do something
};
$(".someclass").on("click", something);
</script>
If I add more buttons from the same class to the DOM, they will have not have the click event binded. So once you load the new content via ajax, also remove all binding and add again (you need to remove or you will have buttons with 2 events).
$(".someclass").off("click");
$(".someclass").on("click" , something);

Ajax.ActionLink and jquery execution in PartialView after Ajax request

I load some PartialView in page as response to Ajax form post. This partial contains two Ajax.ActionLink by self. After response load ActionLinks doesn't work properly - it send request to server but doesn't updates UpdateTarget with returned content.
Seems like jquery-ui provided widgets (like draggable) can't bind to elements in way like this (code placed in partial view):
$(function(){ $('#target').draggable();});
I would appreciate for any solutions.
PS> ActionLinks starts work after target id correction, but jquery ui steel don't work
seems #target is not avilable when your code is binding the handler..
try using live(), or delegate(), or .on()
Solved by add named function in PartialView and call it in OnSuccess for Ajax.BeginForm. As I discover document.ready fires for ajax-loaded content before page is really updated.

How to trigger unobtrusive javascript when the content is dynamic with ajax (Lightbox)

I've got some links coming in from ajax that need lightbox functionality:
<img src='...'>
Normally this is given behavior via an on page load handler, but since the content is coming from ajax, the UJS isn't getting triggered.
Any way to do this?
If the content is coming from AJAX, then din't setup the event handling during page load. Instead, let the event bubble to the topmost container that is not being changed or replaced by AJAX. Worst case, use document as the topmost node.
$('<root element selector>').on('click', 'a.lightbox', function() {
// activate lightbox on the clicked element.
});
I'm not sure how you're triggering the ajax requests, but if it's with jQuery which seems likely, you can bind the lightbox in the success callback:
$.ajax({
url: '/route',
success: function (response, status) {
$('.lightbox').lightbox();
}
});
You can pass in a context to the jQuery selector so you don't re-attached the lightbox to links that are already in the page, for example if your ajax call is adding the links to a div with id 'lightbox_links', use this selector instead:
$('.lightbox', '#lightbox_links').lightbox();

Google analytics and loading a page using ajax GET request

I have a mobile site which completely runs using AJAX, and hash code, basically each page click is a link, such as
<a href='http://some-domain.com/my-page-122.php" hash-id='122'>linkage</a>
Meaning that the page itself exists and it has ON IT google analytics page, HOWEVER, on the ajax request, I only ask to load a certein <div> on said page using jQuery's load(), so my question is:
because the page is called for in it's entirety with the google analytics code and everything, will it still record it as a page view even though only a portion is injected to the page?
The reason why I'm asking is because this site is getting around 500 uniques per day, and we want to change it to this new AJAXy form, so not recording analytics is a big no-no.
If you use jQuery you can bind to the global AjaxComplete event to fire a Pageview everytime an Ajax call completes:
jQuery(document).ajaxComplete(function(e, xhr, settings){
var d = document.location.pathname + document.location.search + document.location.hash;
_gaq.push(['_trackPageview', d]);
});
If you update the Anchor every time you do an Ajax call this will fire the full path including the anchor part of the url.
Note that if you load content using .load that has the Google Analytics Tracking code in it, it will run that code and fire a second pageview. So you want to make sure you don;t include the GATC on the ajax content to avoid double pageviews.
Analytics won't record it automatically. Assuming you're using the asynchronous code you can record as many pageviews as you want by writing to the gaq array using an explicitly set URL:
_gaq.push(['_setAccount', 'UA-12345-1']);
_gaq.push(['_trackPageview', '/home/landingPage']);
In this case you can build whatever URL you want where they have '/home/landingPage'. Note that if _gaq was already properly instantiated and _setAccount was already pushed then you only need to push the _trackPageview.
Also, the event can be in code returned by your AJAX, or it can be in the click event of your button or whatever is launching the AJAX request.
See http://code.google.com/apis/analytics/docs/gaJS/gaJSApiBasicConfiguration.html#_gat.GA_Tracker_._trackPageview

JQuery - Ajax return HTML wont allow further Jquery functions?

Kinda New to Jquery and hit an issue regarding returned HTML. I am using the .load() function to load HTML returned from a jsp file - its all working grand except the returned HTML doesnt seem to allow further Jquery functions to be called on it.
i have a click and toggle combination running for "#showgame" - this id is in the returned HTML but clicking on it does nothing when it should. Do i have to update anything to tell jquery that this id now exists on the page after load() call?
Regards,
Cormac
You need to use the live() function to bind the click event.
$("#myelement").live("click", function() { });
Live binds the event to current and future elements that match the selector.
