I am using ASP to make an application. What I want right now - is to
make the self updating list of the users online - based on thier
cookies. In my opinion all seems to be writen well with it's logic, but
computer thinks otherwise. I use application("loged") to store the
cookies of all users. Code:
I have the AJAX-script. It eats memory about 4Kb per one callback.
Script reflects messages from server application in real-time. I form
messages, and put them into the iframe. If mesages more than 40 last
message delete. Can you check the script and say about my mistakes? Code:
how to manage the script scope on a full ajax application Let me explain a scenario
- Pages are loaded dynamically in a div,
- pages are php files
- pages contains scripts tags (static and generated via php) depending on
context
Load Scenario :
1. master page load pages via $.load jquery function
2. page are inserted and the script is executed (mostly input events or live events)
when i select another page (just imagine a combo with all pages listed), the Load Scenario is executed again... the 2 js code line that matter in the master page

I can't seem to get the row striping working with my application. The table data is being pulled in via AJAX and for some reason that is interfering with the striping code. It's hard to debug also because the table info doesn't show up in a view source.
The code I am using for the striping and AJAX is:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript">
$("tr:odd").addClass("odd");
</script>

I've googled the heck out of this, and although I'm finding plenty of solutions, I'm having trouble understanding them. I'm very new to jquery, and brand new to ajax. My problem is, I have a php application using several jquery effects. I've just started learning ajax and it is going really well, this stuff is incredible! But all the ajax loaded data loses the jquery effects. I get that it is a DOM issue, and I've seen that others have used "live" (i think?) to fix this, but I honestly just have no understanding of how toimplementanything that I'm seeing.
This is part of my ajax...
And this is the main effect I need to get working.
Ok, so I've built a member search using ajax to change the results each time a filter is changed. It works great, except one minor issue that I'm struggling with...I just can't specify dynamically in the parent file that linkclass$id opens linkclasscontent$id as I don't know of any way to pass that $id variable back over to the parent.

The problem that i have is titme to time the script uses with that ajax query doesn't work especially when i stay long time in a page.
This is my code?
Why it works most of time but sometime doesn t work? is there any specifications to take for the unload event ?
I have a graph that i need to be dynamic in the sense that a user would click a checkbox and select which info will be displayed. I can do this using php, but i want a seamless transition done. My thoughts are AJAX SO basically i need a way to send a a request to a php page lets say graph.php with a variable set liek so: graph.php?id=1
Can someone point me in the right direction regarding this please, i presume i can use the onCheck on the check box and have a small function to handle the ajax request, Just to summerize:
Checkbox Clicked --> Request to php page with a variable set --> Return the php page.
<script>$(document).ready(function(){
$('td img').click(function(){
alert($(this).attr('id'));
});
$.ajax({

I am new to jquery and I was wondering on how to send the id of the image I clicked on to a ajax call.
I'm trying to access a variable that is created after an AJAX request was successful, to re-use it in parts of my code:
$.ajax({
url: 'http://api.twitter.com/1/statuses/user_timeline.json?callback=?',
data: {screen_name: 'danmofo', count:amount},
type:'GET',
[Code].....
Is there an alternative method to making the variable tweets usable outside of $.ajax ?
I use JQuery validation plugin to handle my forms, and I'm using the remote
option for some inputs, aside from the usual 'true/false' to detect if the field is valide or not, I need to get a php variable generated on the server, but I don't know how to do it
I'm not familiar with javascript/ajax. I'm more in the PHP/Mysql section.I'm using an ajax auto complete function found online to look up a value and return results.By default the INPUT FORM sends the variable "inputString" to the javascript that sends the variable "queryString" to the PHP query.What I would like to do is send two variables, instead of only "inputString".As you can see from the above PHP Query I am trying to select WHERE $queryString AND $os Querystring is being sent to the PHP query, but how do I send the second variable?

I have a webpage (Perl) that allows a user to select one of two buttons that represent :

Based on the button they choose, I need to pass a variable (declared in Perl) to another Perl page that is responsible for updating/inserting in a MySql Database.
As you can probably tell, I'm new to this. But I'm not sure how the variable ($name1) can be used in Perl to the loadXMLDoc, and then get passed using the 'POST' technique to mysqlinsert.pl??

I have been struggling with an AJAX issue for 2 days now and have finally started looking for some help. This is my first post on this forum but by the looks of it , it seems to be full of people who know what they are doing so I humbly ask your advice on this issue. I want to build a javascript function which can retrieve data from an SQL database by calling a php script. For this I use the script underneath. There is off course a php-part to this but the problem is not situated there since the script runs smoothly if I put the returned value (ajaxRequest.responseText) into an html-element like a <div> for instance.
If I don't do this however and just want to assign it to a javascript variable (like shown below : window.out_text = ajaxRequest.responseText) it will not show when I call document.write(window.out_text); EXCEPT WHEN THERE IS A DELAY. So If I put alerters in there to slow down the generation of the final html, it seems to be able to write the javascript variable to the screen. Is this a bug in the ajaxRequest.readyState? Or am I doing this wrong? And especially: How can I solve this. Someone else on this forum must surely have already ran into this problem?
[Code]...
The best way to describe what im trying to accomplish is with a code
snippet. Im using the free .NET ajax library.
<script language='javascript'>
function proc1()
{
myFunc("MyCodeBehind.MyAjaxProc");
}
function myFunc(procName)
{
procName("My Parameter", processMyFunc);
}
function processMyFunc(response)
{
// Process response from the server
}
</script>
So im essentially invoking an Ajax function , but I cant explicitly use
the name of it like so
MyCodeBehind.MyAjaxProc("My Parameter", processMyFunc);
That line would work fine. Clearly though, this doesnt work
var procName = "MyCodeBehind";
procName("My Parameter", processMyFunc);
how to get the result of the Ajax Response in some variable
i am using the following code
AjaxGet = function (url) {
var result;
$.ajax({
type: "POST",
[Code].....
Now from above code i want to store the result in some varialbe like below,
PM = {};
var output;
PM.projects = function () {
var data = AjaxGet('admin/DataService.asmx/HelloWorld');
alert(data);
}
Basically I want the field name to be a variable but it is taking it as a literal.When I print back the POST array with PHP I get:- Array ( [field_name] => Whatever I typed )So if the text field has a name of 'username' then I want the PHP to print back
Array ( [username] => Whatever I typed )
$(function(){//on DOM.load
$('.register-field').blur(function() {
var field_val = $(this).val();

This is my first adventure into PHP/Ajax/MySql/Javascript and is pretty much my first web project. I've been trying to tackle this problem for a little over a week now. My main objective is that I want to display php content pages inside a div on the index page without refreshing the page (iframe style). I don't want to stop search engines indexing the individual pages so I need a mechanism to redirect to the index page so that the page is displayed properly. I'm not bothered if it takes them to the exact page and I'm redirecting them to the section of the site where they the page is kept.
I also want a mechanism to redirect if a second search engine link is clicked that belongs to the individual page (ie image links that belong to the same page). This is only a problem because the php session has already been opened and a php variable has been set by the first redirect. All the redirections are taken care of by PHP and I got the redirection of multiple instances working ok by setting and unsetting session variables. This PHP code is included on every content page.
But, when I added links to the index page and try to navigate between pages, it all goes pear-shaped.When the links are clicked it calls up the Javascript code, inside which a PHP variable is set (I dunno if this is the "done" thing, but I came across the solution somewhere on the Interweb). This is the first thing checked when the content pages are called up. If the variable isn't set, then it runs through the redirect options.
The problem is that after clicking the link when the page displays it always refreshes the index page which I don't want it to do and which is why I'm thinking it's the setting of the PHP variable inside the Javascript that's going wrong. (Also why this question ended up in this section). Is there any way of getting this going without passing the variable into the url (not that I'm against this option)? Index page code, PHP Code (before HTML)...
Code:
<?php
if(!isset($_SESSION))
{
session_start();
}
// set the session var to the index page url which I think remains until browser close
$_SESSION['pagecheck'] = "http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
// set the section var if it hasn't already been set by one of the content pages
if(isset($_SESSION['sectNum'])!= "undefined")
{
$_SESSION['sectNum'] = "0";
}
function getSection() .....
Additionally, are there any potential security threats that should be tackled (bearing in mind that I don't want to use cookies, I'm not against this either but decided if they are switched of it may become an issue, and I'm not going to be handling any sensitive information). I really don't want to use Iframes due to any javascript switching off related problems (yes there is a javascript testing function included in my full code!).
I have been trying to figure this out for a few days now and have finally come to the point where I think I got it but may just need a little push to get what I want.
Heres the situation:
I have this function that uses ajax to access a database and returns the results in the responseText. That part is working fine, I have confirmed that the responseText contains the information that I need
**************code*****************************************
//new ajax already created and assigned to the variable xmlhttp//
var response_recieved = "some data";
function get_answer(Table_Name, Field_Name, Data_Type) {
[Code]....
As evidence by my posting, this is not working correctly. The variable response_recieved is coming up undefined outside of the callback function assigned to the onreadystatechangeproperty.
Based on the information that I have gathered online from various forums, I believe this issue has to deal with a problem with closure in the callback function assigned to onreadystatechange property. I don't think it has any. Based on the fact that there is no anonymous function in that function. But my problem is that the call back function is anonymous itself... I think???
get the variable response_recieved to survive outside of this function.
Theres nothgin wrong with my ajax, it works and is sending other variables but whe i want to send "pood" from
function farmers(pood, happy)
i twill not work. now when i call the function it goes like this code...
now it will not send PISSLET, what do i do?

I am trying to fix up some code and have run into a problem. For some reason the line of code
Code:
var sizeQ = gid("q" + aq).length;
is not assigning a value when the page is loaded in firefox but in IE it works perfectly.
Code:
function testAnswers(aqNow,review,toClose){
//alert("inside test answers");
var listQa = gid("listQuestions").value;
[code]...
Im trying to send JS variable thought the jQuery Ajax,The problem is that the php page recive only null ....
My code below:
Code:
$(document).ready(function(){
$('#start').click(function(){
$('#text').html($('#file').val());
