Ajax :: Indexable And Facebook Functionality - Div Appears Empty In The Source
Mar 17, 2011
I've been trying to learn Ajax and have been following these tutorials:- [URL] I now have it so that in my site when a user clicks tabs the content gets loaded into an originally empty right hand div without any page refresh. However I notice that as content gets loaded into the page if you right click and view source the content is not there and the div appears empty in the source. I understand why this is but I also understand that this will make the site a lot less seo friendly which brings me to my questions:-
1.Facebook pages seem to load in their content without any page refresh at all yet it seems this is actual indexable content being loaded in live or am I wrong?
2. If this is the case that they load in actual indexable content live at such speed how can I do this because I want the content in my loaded sections to be indexable yet also want the site to flow seamlessly like facebook with no page refresh at all? Are there any examples/tutorials on this?
3. I've also noticed facebook urls change as the user switch tabs yet the page itself doesn't refresh. How can I do this too again whilst keeping th page as indexable as it would be using a regular page based layout?

I'm using the following css code which wrapped around a dynamically populated field;<span class="ui-widget-header platform ui-corner-all"></span>
When the span is empty I want to hide it, and I've used this jquery to do this.
However, the ui-widget-header class appears to be stopping it from hiding - if I remove this class it hides fine.

Below I have a facebook login/logout script for my website. The login works fine. The AJAX requests the php file, waits for the "Success" response, and then reloads the page. The logout doesn't. Instead the browser goes to the PHP file with just the word "Success" printed on it. I've separated the xml request as a separate function but that doesn't appear to solve it either. code...

A lot of websites have a chat system built into them.
I assume they work something like this:
User1 enters message
AJAX posts message to server
Server holds message
User2 does ajax get to check if there is a message
If there is a message when User2 checks the server responds to the ajax request accordingly Rinse, repeat.
I guess ultimately what I am asking is there an interval set to constantly check the server? Or is there another way of doing it.

Im a bit curious about this Facebook's useful functionality. When I paste a URL on the 'What's on your mind?' box, it almost perfectly gets the body of the article. How does Facebook do this?

I am building an all AJAX site for a Facebook iFrame page and am having an issue. All the pages and what not load up dynamically just fine, but some pages use the Facebook commet system. After the AJAX has loaded the page though, the JavaScript inside does not load.
This is the Facebook comment script that I need to load inside the ajax'd content.

I am trying to use jQuery's AJAX functionality to make a progress bar. A request is submited via AJAX, which starts importing data to a database. Once submited another AJAX request is called on an interval which checks the progress of this import, a progress meter is then updated using this information. However, the progress AJAX call which is fired on the submit of the form only returns once the import has complete. Its like its being blocked by the initial request? How I can get both calls to work at the same time?

I have web video player that can display adds by inserting a div tag on top of the player after an amount of seconds that I specify.
I would like to manipulate the content of the div tag with jquery but I can't do this since the div tag is not present when the document is loaded.
I have looked into several options.
But all the solutions seems to rely on an event to happen - a link is clicked, some element is mouseovered and then jquery runs throug the DOM again.
But in this case no event occurs! The user click play (on a flash player) remove the hand from the mouse and 15 secs later the div tag with the add is displayed.
Is there any way to select this div tag and manipulate the content?

I have a webpage (on a Drupal website) which is currently using the jquery tabs javascript. Each tab dynamically loads content through an Ajax Call.Drupal has a javascript file called tabledrag.js which allows the users to order the elements of a table by dragging them up and down in the list and this will reflect the elements position when you submit the form. When the content of the Ajax tab loads, I need the document.ready code (or drupal.behaviours, the equivelent) to fire off.However, this code has already fired when the page first loaded, as opposed to the content inside the ajax tab. How can I force reload the tabledrag.js so that it will re-run its document.ready behaviour?

I use AJAX functionality in my project & my coding something similar to the following:
$('.home').click(function(event){
event.preventDefault();
$.ajax({
url: 'home.html',
[Code]....
Initially I (successfully) tested my project after deploying to the Apache server which is running in the localhost.
But, if I just open the page in a browser (without deploying to the server), the project works fine! How this is possible?
According to my understanding, if we send an AJAX request, which is really an HTTP request, which has to be received by an HTTP server and the response should come from the server.

I'm writing a firefox addon to readout the facebook-privacysettings of an user.
[url]
There are a lot of "Edit settings" which open a dialog like this:
The HTML code looks like this:
My solution idea was to fake the ajax call like this:
I got this parameter from Firebug, and i get the same answer as the "manual"-click. It's javascript code, beginning with "for...". however the dialog doesn't open, the DOM node isn't added and i get the alert "Error! Status = 200 OK"
So I just figured: why the comlicated way with ajax, can't I somehow fake the real manual click? If someone knows a way with ajax or faking the click?

Im using keyup function to track text typed in input box. The idea is to perform incremental search in db. This works fine. After this I update the html dynamically to display the filtered resuts and at the same time I must dynamically rewrite the html for input box code. After this the keyup function is not working anymore, allthough the id tag is the same? How should I get around this?
$('#filterBox').keyup(function() {
$('#status').text(this.value.length)
if (this.value.length > 2) {
filter($.trim(this.value));
}
});

I am making a call like -
$('#display').load(adnwurl, function(response, status, xhr) {
alert(response);
});
And also tried with -
$.get(adnwurl,
{},
function(data) {[code]...
In both the cases I am getting an empty response instead of expected html response.If I just copy paste this adnwurl in browser, I do get a proper html response. Its not working with ajax call.
adnwurl = "http [url]...site_id=4764&partner_id=70606a913077034c&timeout=5000&version=1.5&language=jsp&format=wap&testing=1&target_params=AGE=>29||DOB=>1981-08-[code]....

So I'm having some issue with an ajax call I'm making. The success always returns an empty string no matter if what the php function returns. It seems that looking in firebug the function is called and I've tested it by sending myself an email. It just happens that it is always an empty string. And I am very confused because I developed it on my local server and it worked just fine.
[Code]...

The goal is to change the source on the fly (as with a firefox extension webdev or another or even Greasemonkey) to add a link. Until then, easy does it work well. This link launches an application ajax jquery like:
$.get(...) or even $.ajax(...)
If I'm on [URL], added my link, I click and it works, I see the ajax request and pass my "alert ()" gives me the return of application. Great! But if I'm on a site other than mine (the url of the ajax request is [URL] while I'm at [URL] for example), the return of the ajax request is empty.

ser is able to create queries and issue them. The query is sent to the web-app by means of an ajax call. Then, the server computes the result set and a small subset (100) of tuples are sent back to the client for visualization.
These thing works with queries that are simple and do not require to the database long computations. As soon as I try a more complex query (computation requires ~ 7secs), the answer returned to the client is empty.
I suspect that this is a problem of timing out the connection, is that possible?
(edit) I have almost forgot, I'm using Prototype as JS library

I've got some Javascript within a div that's displayed by a Modal Popup Extender. The Javascript is throwing an error. When I go to 'View Source', it appears that the source for the Modal Popup Extender and the Javascript contained therein isn't there. How can I view the source then? The Modal Popup Extender *is* being rendered.

I got some code that loads divs from other web pages into a particular div in my main page. In other words, I click on a button, and this tells jquery to load afragment of a particular page into my main page. For instance if I have 5 web pages onrock stars, I could have 5 buttons, and each button could load one rockstar's biography into a div on the main page (and replace whatever was there before). This works, and I do see the content that it loaded. But when I do 'view source' in IE, I do not see that content (the bio of the rock star). Another clue that this content is not really there, is when I try and run some code on that content. The content (from those external pages) have divs with specific names, and I try and make them into collapsible panels by running the following short function:
var IdentifyPanels = function() {
$("DIV.ContainerPanel > DIV.collapsePanelHeader > DIV.ArrowExpand").toggle(
function() {
[code]....

recently i noticed that all of my embedded JavaScript code and external style sheets are being shown IN "view source."
this happens in all browsers ( IE, FF, Chrome, and Safari [windows]) ... oddly enough it only happens when viewing on my vista or win2k3 machines. is this something added to these OS's or the result of an installed program? has anyone seen this before?
