I'm creating an AJAX page that is built using a PHP Class, ie the php looks a bit like this: PHP Code:
$wp_page->addjs('../var/savepolicies.js')
$wp_parser->page = "userpolicywindow.php";
$wp_parser->addlink("Home","../index.php","");
$wp_parser->addlink("Logout","javascript:logout();","");
$wp_parser->getpageid("501");
[Code]...
within this page that has been created, there is an AJAX tree folder which calls another page to be loaded into a DIV by AJAX again. Code:
[Code]...
I don't know why it doesn't work because the page has been loaded with the JS file, but as soon as the link is added afterwards it doesn't work. I take it this is because it doesn't know where to find the JS, but how can I overcome this?
jquery provides ajaxStart() and ajaxStop() events. Those two events do not seem to be triggered if the ajax requests are made by Microsoft Ajax tool Kit (from ASP.Net code). Is there any way to bridge those two event models? If not currently possible, is there any future initiative or plan out there to make this happen?
View 2 Replies View Relatedi was using $.ajax method to get my ajax page on my main page,which is working great.But now if i have links in that ajax page then i can't open them in that same div,the links are opening in new window,but i want to open in same part,i tried google it and then found, i have to use iframe instead of div.how to do with only use jquery and div.
View 3 Replies View Relatedi have a series of <select> fields. The first one, via ajax(), generates a 2nd one, based on the first ones' data with the .change() method. there is then a 3rd <select> - who's data will depend on choice of the second one although step 1 works, and i can generate the 2nd one, i still can't generate the 3rd one.
when i test the script on its own, both the 2nd and 3rd <select> fields are fine - but not via the ajax, which leads me to believe that the .change() from the 2nd one, isnt triggering the ajax call - its not being picked up (even the 'hello' alert isnt working).

I am using jquery for getting ajax responses from server side functions.
I am in a situation where I need to make two ajax calls one after another and the second one is dependent on the response of the first one.
I have tried to use a code which is similar to this one?
$.ajax({
type: 'GET',
url: 'myURL',
success: function(data)

I was playing a little bit with a lot of ajax frameworks. I have even
wrote one small by myself. But one thing still drives me crazy: Whenever
I'm doing an ajax call I need to specify handler to handle data coming
from a server script. That means that almost for every action I need two
functions.
Since I'm still new to all of this I'd like to ask how can i achieve
something like this:
function function_name(el) {
var i_need_this = get_what_i_need(el.id);
return _i_need_this;
}
where get_what_i_need function is returning some information using ajax
from a server.

I need to resort the contents of a table, that gives me the results

View 8 Replies View RelatedI've noticed a strange behavior with Ajax in internet explorer. In my page I've four links, that call four different pages by using XMLHttpMethod. By entering for the first time in the page and selecting the various links, all work correctly (the 4 pages are called and displayed into the page), but if I click again on a link previously clicked, trying to repeat the call, the responseText won't to appear!

I found a joomla template over here that has just what I want. I don't use Joomla, I'm a wordpress boy, and I also don't really want to dig in there and rip it out.

I'm currently engaged on a dissertation which is
investigating AJAX technologies and I was
wondering if anyone had any references that might
shed light on the subject?
I will of course carry out a literature review but

Can someone recomend me some good AJAX book?

I have strange situation, in my webb apps i use a lot of AJAX.
in my developer computer i use opera and naked apllication (it's using
Python Application Server cherrypy www.cherrypy.org), in production I
covered my application be Apache server which serves static files. The
problem is that AJAX working in Opera but only on production server
(cherrypy behind Apache), on developer machine it's not working. Others
browser (IE, FF 1.5.0.1) working without any problem. Does anyone know
solution for this? Or is is a way to lookup what is happen under Opera
engine? any plugin or something what shows AJAX status call?
i look for a simple ajax, for a beignner, able to send a request for a text file and show its content in a <div />.
View 6 Replies View RelatedI am having difficulty on maintaining session when using ajax.
I first load a page with a session genterated. But since AJAX is a
client side activity where I sent an AJAX request to an url without any session
info. Of course, the server will create a new session. Even though I
can write the session id into the first page where I made ajax calls, it is not a secure way...
How do people deal with this problem?
I have a large table which pulls data from a mysql db. Because of the large
number of records, it clugs up lot of memory and the browser massively slows
down when scrolling down.
What I would like to do is pull say 50 records and make the scrollbar as
long as if all records were retrieved; then use the on scroll event to
retrieve another 50 records based on far the scroll was (i'd assume using
ajax).
I'm trying to get my PHP scripts to email me an email which includes a
button to enable a feature, which I'd like to be done via AJAX so the
user can open the resulting page within their Outlook email rather
than having to open a web browser.
My script is below, however I'm slightly confused, because when run in
Outlook or outside the webserver directory it won't work, but run
inside, it will. Can someone explain what I'm doing wrong? I may have
seen somewhere about accessing XML on another server - is it that AJAX
can't access files from a different URL? Code:
I feel like I should be beating a dead horse here, but I've done quite a bit of research and this is not making any sense to me. I'm trying to read an XML document returned in the XHR back from a .load() method. I can't get anything to happen in IE, and it really seems like I'm having to use the WRONG way to get it happening in Firefox and Safari.
Here's some code, the handler passed into the .load() method.
This function traces that the length of the results that are "facility" elements is 0. This is absolutely wrong, as there are 5, and if I set my resultsXML var to the string that is the XML from the response, Firefox will accurately count the elements and report them as 5. However, I understand I'm supposed to pass an XML Document object, NOT a string into the jquery object so that I can parse it correctly in any browser. IE always reports the length as 0 regardless of whether I pass the string or object into the jquery object. But even in IE if I trace the value of the responseText string, the full XML document is seen.
so i have this "class" defined in a javascript file, "a.cross-link". This enables the ability for users to navigate the webpage in a slider format.it works fine if I directly place the required html code:
<a class="cross-link" href="#3" title="Go to Page 2">View Results</a>but if i have php print out that line for me, it doesn't work:
echo "<a class= "cross-link" href="#3" title="Go to Page 3">$name</a>";(Where $name is some variable)
Note: the php code is just your average sql stuff. here is an interesting observation i've made: if i "hardcode" this this into the html:
<a class="cross-link" href="#3" title="Go to Page 3">View Results</a>
and then i go to generate the sourcecode, this is what appears (this works): <A class=cross-link title="Go to Page 3" href="#3" jQuery1283131847233="30">View Results</A>
but if i have the html made by a php echo statement, it just stays the same - i dont get a jQuery1283131847233="30" generated in the sourcecode.i'm new to jquery and ajax stuff. to me, it seems like the "cross-link" class i have defined in the javascript isn't being applied to correctly.can you invoke javascript from a php echo statement that is formatted to produce html code? here is another thing i believe is true: when the page loads, the javascript loads. the users, through the use of ajax, submitts a sql querey and navigates, using a jquery slider, to another div (where i want the user to go after selecting a resulting link from the sql query). so the javascript is going to execute before the list of results is produced. do I need to rerun the javascript each time new php produced sql data is populated in a div? if so, how?
Is it possible to stream XML data from a file using AJAX?
The xml file is constantly being updated by a backend program, I currently have a javascript that has a timer, every second it just runs a loadXML() function to return the XML data however having a few problems with the javascript tripping over itself.
Wondering if AJAX has streaming abilities?
Also, can someone please clarify for me, is the xml dom javascript, or ajax? As I have just read a ajax book that tells you to use xmldom to read xml data but im already doing that, with javascript, what is the difference?
