AJAX :: Data Returns Out Of Sequence
Jan 3, 2011
I'm building an application that uses calendars extensively, I have single calendars returning nicely but I working on a section that can return multiple calendars (eg. yearly overview) between certain date range ranges. It's working fine but the calendars are appended to the div when the server responds and not in the sequence they are called.
Here's the code I'm using:
Code:
function displayMultiCalendars(date1,date2,a)
{
$.get("<?=base_url();?>cal_center/get_date_range_total/"+date1+"/"+date2, function(data) {
[code].....
So, is there any way of making sure that they return in sequence? I'm sure there's another/better way of looping but I'm not the best with the js/jquery.

Can somebody take a look at this...
The white my notes section on the bottom left is a div area that is loaded with an Jquery Ajax call just like 2 other areas on the page. This works fine in IE, Safari (PC), Chrome but not in Firefox. It just shows blank white.

I have a text-box. On the event of `OnKeyup` a function is triggered that looks like this:
$.getJSON(url,function(data){
$.each(data, function(key, value) {
showSearchResult(value);
});
});
No my problem is that when you type really fast then the return search result does not always return relevant to the current value of the textbox.
[I did think of adding a very small time-interval on the onkeyup event but i thought there might be a cleverer way of doing it ]
This problem is because the Ajax calls do not sometimes return in the same sequence that they were fired.

$.post, it calls a php file which retrieves data from my database and should return a JSON datatype result. I checked on firebug, and it does successfully retrieve the data in JSON format. I however cannot get it to display on screen. I want to populate input fields with the result accordingly.
Here's a chunk of my javascript: (this function is being triggered by a dropdown)
function updateBillingAddFields(address_book_id) {
jQuery.post("ajax_checkout_confirmation.php", {
address_book_id: address_book_id,
action: 'get_shipping_add_details'
}, function(data){
var form_element = document.forms['address'];
form_element.elements['entry_name'].value = data.entry_name;
form_element.elements['entry_addr1'].value = data.entry_addr1;
form_element.elements['entry_addr2'].value = data.entry_addr2;
form_element.elements['entry_addr3'].value = data.entry_addr3;
form_element.elements['entry_addr4'].value = data.entry_addr4;
form_element.elements['entry_postcode'].value = data.entry_postcode;
form_element.elements['entry_state_name'].value = data.entry_state_name;
}, "json"); }
I tried putting alert inside my function, and it also doesn't show. I'm thinking it doesn't go inside the function at all.

I'm using the $F of the prototype library to send data through the Ajax
Request. I'm having problems using the $F to reference fields sent
back through an original Request. My first request sends a form back
to the user in the type such as <input text name=foo> and at the bottom
of the returned form I have a second ajax call to send the fresh data
to the another script. The problem is that the new data in the form
cannot be referenced from $F. My question is how can I pass the new
data in the javascript to another Ajax call either by $F or by other
means?

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.

I'm new to ajax. I've made a script that should return results from database but it keeps telling me just undefined. Code what I have:
Code:
var ajax = null;
function showRes(wut) {
if(wut.length == 0) {
document.getElementById("results").innerHTML = "";
return;
} if(window.XMLHttpRequest) {
// IE7+, ff, chrome, opera, safari
ajax = new XMLHttpRequest();
}else if(window.ActiveXObject) {
// retards
ajax = new ActiveXObject("Microsoft.XMLHTTP");
} else {
alert("Your "browser" does not support AJAX!");
return;
} var url = "search.php?q=" + wut;
url = url + "&sid=" + Math.random();
ajax.open("GET", url, true);
ajax.send(null);
document.getElementById("results").innerHTML = ajax.reponseText;
}

<div>I have a bunch of ajax events that are fired one after an other to fill different spots on the page.Hence it's important that I know which dom element each on of the resulting data is supposed to belong to.</div> <div> </div><div>I was wondering if there is a way I can pass the id of each element into the call so that it gets returned automagically without any intervention by the server?</div><div> </div><div>In YUI I can pass any number of arguments to an axax call and these areguments are available as part of the response.</div>

I am getting an error to a mysql_query() call: Access denied for user 'SYSTEM'@'localhost' (using password: NO)' in path 'C:PHPClassesMySQLDbClass.php' at line 1078 This is coming from using a XML HTTP Request object (AJAX) to send form data to the server requesting my DB records interface script page, ajaxRecordsInterface.php. In using PHP sessions, I have no problem going from a logged-in-select-activity PHP document to an activity controlled by a PHP document that does records interface. But apparently an XML HTTP Request object has a different session than a PHPdoc-2-PHPdoc session. Is that so?
Here is MORE DETAIL: I am building first a version of a web-based database interaction using MySQL that does not use page reloads, so that means I am using Ajax/XML HTTP request object/Javascript (later I build the version that does script-free page reloads to show db updates/refreshes). I have no problem with login whose first PHP document gets user information and presents it, as well as a menu of links to how to interact with the DB. One of the options is to add/edit/delete student records.
In the PHP document which is the DB records interface, I have a scrollable HTML table at the document top with one table row for each record. Below it is an empty form, whose fields get populated when the user clicking on a record in a table row. Note that all fields for the records in the table rows were delivered as a Javascript array with a maximum of 50 or a 100 contiguous records in the MySQL table. (More optimizations may be done later, such as creating a Javascript array as a "cache" of the last 20 or so selected records.) I don't have problems making mysql_query() calls in a series of PHP document requests. I call session_start() to get session variables, one of which is a serialized MySQLDatabase class object which I unserialize to get the object again. The problem is the XML HTTP Request to a PHP document designed to interact with it is a different PHP session from a page-to-page session.

I am using .ajax() to access cross-domain data using JSONP. Because I need to be able to cache the data I want to use a static name for thejsonpCallback function, so I have set the jsonpCallback option in the .ajax() request. However that appears to requires a global function whereas the auto generated function didn't (well maybe it did but that was all hidden from me).
I definitely need to be able to cache the results. Ideally I wouldn't have a global function handling the data. Is there another way to do this? If not what is the best practice way to go about using a global function these days and how do I provide it with the context of the object/module it was called from - which is where the data is needed?

I am still new to jQuery and I am trying to figure something out. I have this code:
[Code]...
This is working fine on itself. What is does is when I click a link it loads data into the following div. When done loading it slides out. But I want to change the appearance of the slide. I have tried to do that like this: $(this).show("slide", { direction: "down" }, 1000); But this doesn't work. When I check firebug it says the following: o.easing[this.options.easing || (o.easing.swing ? "swing" : "linear")] is not a function

i 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 have a number of sources of javascript and don't really know the sequence of when each gets loaded.
<SCRIPT FOR="window" EVENT="onLoad">
var tmp = "where are you";
</script>
<script language="JavaScript">
alert(tmp);
</script>
<script language="JavaScript" src="code.js"></script>
Are they loaded based on the order they are seen in the page?

I have 6 headers that are animated gifs. They transition, 3 of them left to right, the other 3 right to left.I would like to have them to change to next header in sequence no matter which page on my site they click.I'm not sure this can be done, but think javascript is my best bet. Can anyone point me in the right direction?

I am creating a little portal for my design department at work. On the homepage of the portal, there is a section for a random image that people can submit. This image has a preset width and height so it fits into the layout. When you load the index page, it randomly selects one of the images from the database. However, I want people to be able to click on the image and load a different one. I don't want to reload the entire page and get a new randomly selected one because it is possible they could keep getting the same image over and over. If they random get image #5, I want them to see image #6 when they click, then image #7 when they click again, so on and so forth. When they reach the last image, they go back to image #1. Make sense?
Any ideas? I have tried looking at scripts that automatically change the image (with cute little fade ins), but I want the change to happen based on the user's actions.

As a test, I'm trying to display a sequence of images on an html page. The first image is displayed initially, but when I click on the button (although I can tell that the sequencing is happening, and the image files are on the server where they're supposed to be) the rest of the images do not display.
<html>
<head>
<style type = "text/css">

For the moment disregarding function thirdPic, I am able to click on "sample text" and I switch from an invisible image (actually 1 px by 1 px) with a picture of a book with a quote (firstPic) that I want to appear on screen. After reading the quote the reader can click on the image of the book and it will disappear. And it works fine. However, there are a couple of cases where I would like to show a lengthier quotation which would require me to click on the first book image(firstPic) and a second book image would appear with more text(thirdPic). I can get the second image to appear but I can't get it to disappear. Or I can get the first image to appear and get back to the empty screen but I want to do both.
Everything I've tried to do doesn't work. I DO NOT WANT TO HAVE BUTTON TO CLICK THROUGH A SLIDESHOW. It would not be the representation I want ot produce.
Javascript Code
----------------------------------
function firstPic()
{
document.getElementById('blankPic2').src="../images/pic657.gif";

I created an internal application which shows a large list of tasks that will be completed on a server by a script. It will go through each in order and update a database with its status (E.x "Failed", "Good", "Errors: <msg>").What I am doing currently is pulling the ID's of these tasks from a database, and then passing them to JQ to .load() the actual content for each div.What I would like to do is figure out a way to have each div reload as something is happening to it. So, lets say the script fires on the server and begins to process task ID 1. I would like to figure out a good way to be able to instantiate reloading for each div, as it is being processed.I do not wish to reload the entire page, I would not like for all 200+ divs to be constantly refreshing.
