Screen Locked In Between Multiple Synchronous Ajax Calls?
Feb 22, 2011
I'm trying to make a little loop that in each itteration executes a little php script to send mail with the mail() function. the php script returns either succes or failure. Now its my intention to append that msg to a div, after every execution.
$.ajax({
type: "POST",
data: dataString2,
url: "sendmail.php",
async: false,
success: function(result)
{
showStatus(result);
[Code]...
the show status(result) is nothing more then a .append(result) the zenMails(y) calls this function again to send the next mail. It does work though but it only updates the div after the entire loop is done, i 'ld think it ld do so after every execution since i call the showstatus when the synchronous call is done and only after that i call the next iteration. Is there anyway to work aroud this ? (making the call assync doesnt work , because the port for sending the mail would still be in use)

Basically, what I am trying to do is call several ajax requests using jQuery on the same page, i know that all browsers are capable of requesting multiple requests. However in Chrome and Safari my website works fine, but IE, Firefox and Opera all only call the first request then dont call, the second two. I dont know why though?
All of the code for the site is here: [URL]

I have several ajax calls that originates from the same page its updating. It works perfectly in firefox but in IE it works for about 18 requests and then just stops until the page is refreshed. I thought it was a cashe issue but I have added a variable for that. I think it may have something to do with binding but I am not sure how to sort that. This is one of my functions.

function addLoadEvent(func) {
var oldonload = window.onload;
if (typeof window.onload == 'function') {
window.onload = function() {
oldonload();
func();
}
} else {
window.onload = func;
}}
addLoadEvent(myFunction1);
addLoadEvent(myFunction2);
addLoadEvent(myFunction3);
...etc...
My problem is that some of these myFunction#s include AJAX calls but
the calls depend on each other in such a way that myFunction2 will not
work unless myFunction1 has completed. So what is the "nicest" way to
make sure of this? I've considered putting a hidden element in the
HTML and then changing it at the end of each function call and have
the onchange event trigger the next function call. But this seems very
hacky and overcomplicated - surely there must be a simpler and better
way....?

I'm trying to build a page that has multiple ajax calls on it. When you do it the old-fashioned way with XmlHttpRequest, you'd create a new xhr object for every call so that they execute simultaneously. If I try to do this in jquery it will only execute a call when the previous one has completed. This makes the page load time completely unacceptable. How to improve the performance?

I am working on a project that relies heavily on AJAX calls, they are done in dozens of places. There are a number of places where I would want to prevent the user from submitting information multiple times (form submissions etc ). I am trying to think of the best way to accomplish this.
I could simply disable the element that starts the AJAX call upon the first click and re-enable it upon completion of the call. I have also seen examples of developers using a class to handle ajax calls that store an identifier for the call and if it is in progress any new calls with the same identifier will be ignored.

I have an ajax call that I want to display an ajax loader image before it makes the call and then hide that image after it completes the call. The below code is working fine in FF. But when the code is run in IE, for some reason the ajax call is made first and then the image isn't displayed until after the ajax call has completed. I've tried putting the .show() method before the ajax call and even in the beforeSend option of the ajax call, for some reason IE STILL makes the ajax call, and waits for it to complete, before it displays the image.

I have been using asynchronous requests for a long time. so the response was processed in a callback function. I thought of not using async so i made synchronous requests. The reason is that i dont have to have two more lines for checking the status and the onreadystatechange.... my synchronous requests would be like this...
[Code]....
so from the code you can understand that there is no need of a callback function and if conditions to check ready state... ... So there is no problem in the above code. The problem araises here... if i press the F5 (refresh) key or do a page refresh when the process is waiting for the response i get an (NS ERROR - firefox ( i have not yet checked that in IE browsers) (javascript error) though the process completes successfully. why?
Do we have to check whether the page is navigating away while in synchronous operation and abort the request? or what could be the reason for the error. This will not happen in async requests because that is also the reason for async...

When I try to fetch a page asyncronously I get a status 0 and the response text is empty: PHP Code:
var loaderImage = document.getElementById("loader");
loaderImage.style.display = "inline";
xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function() {
if (xmlhttp.readyState==4 && xmlhttp.status == 200) {
response = xmlhttp.responseText;
alert(response);

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?

I have a search function which works when I only want to have only one search per page, but as it involves a string call I'm not sure how to modify it to multiple search requests on a page.
The below works fine for one call:
<script type="text/javascript">
function showHint(str){
if (str.length==0){
[code]...
The above doesn't work and I am not sure what do about the showHint(str) as clearly I am not representing it properly in my attempt to modify the script.

I am trying to populate two select boxes with over hundred option elements for each. I have succeded in doing so but with a little problem. I make two xmlhttp calls one after another. What happens is that if the first call doesn't make it before the second, the data in the first select box fails to load and the second box succesfully loads data. I am new to the Ajax world but i am sure i am not doing it right.

append.php:
<span>test</span>
jQuery function:
$(function(){
[Code]....
The content will be added on the first click, but not on the subsequent clicks however. The hidden field gets incremented fine though.

i have 4 images that expand onMouseOver and shrink onMouseOut
<script src = 'js/size.js'>
<div id = 'img1' onMouseOver = "expand(this.id)" onMouseOut = "shrink(this.id)">
<img src = ...>
</div>
<div id = 'img2' onMouseOver = "expand(this.id)" onMouseOut = "shrink(this.id)">
<img src = ...>
</div>
etc...
question: when i quickly move the mouse from one image to the other shouldn't i see one expand and one shrink simultaneously? i am currently seeing one shrink, then the other expand after. on occasion the shrink is skipped and the next image is expanded right away.

I'm developing an asp.net MVC app, and decided to take advantage of JQuery's great datepicker using the following code in my master page:
[Code]...
My problem is that the alert block of code never fires. When I change it to occur before the datepicker code, the alert fires but the datepicker part won't work. What am I doing wrong here?

I'm trying to use the jqmodal dialog plugin and everything is working OK except for one minor problem. It seems when I click on the link, the expected action does not occur until I click the second time. Essentially I set up a small test form with a single line put into a table. In that data line is an href, which when clicked calls an AJAX function and returns text, which displays as a dialog. Like I said, this works fine except for the fact that the dialog does not show until the second time I click on the link. I added an alert box to the code, so I know the function is executed the first time the link is clicked
<script>
$().ready(function() {
$("#hrefClick").click(function(e) {
e.preventDefault();

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...

Okay, I am in the process of making an Ajax library for jBeta, and have run into a snag. code..
NOTE - I have stripped everything not-necessary for this code out. If you want to have the rest for testing it can b downloaded from the jBeta project thread in the projects forum (everything is the same except for this Ajax stuff, which I am adding).
Now, as you can tell the two calls are the same. The first one returns fairly quickly, but the second one never returns, and I haven't got a clue as to why (it is late, so I may have missed something). What should be happening here, is that you can have 1 Ajax call going at a time (I know the limit is 2, this is just for dev purposes), when you get multiple calls all the subsequent ones should be added to a queue and then the library should get to them in order (seems to work, it calls the call() function 3 times). For some reason the later calls (after the first one) are never made (I am assuming that is the problem, they should return if they are successfully sent, one would think).

I have a search box which uses AJAX to query a database and return a list of suggestions to the user, it works off the "onkeyup" event on the input textbox.
Code:
<input type="text" id="txt1" onkeyup="showHint(this.value)" />
Obviously this creates an AJAX call for every keypress the user makes and I'd like to make this more efficient by adding a short delay before the AJAX call is made.

In my js application, consecutive ajax calls are made while running in a for loop. I am using prototype.js for AJAX calls. now if I don't call any function on onComplete event then everything is ok. but if I do so, then the function I have set in an onComplete event is invoked once or twice. rest of the time it doesn't work. the code is like the follwing:
/**
* Moves selected options from source to destination select list.
* @param source select list, destination select list
* @return none
*/
function moveMultipleOption(sourceListId, destListId)// single or multiple based on selection
{
var sourceListBox = document.getElementById(sourceListId);
var destListBox = document.getElementById(destListId);
var sourceTableName ;
var destTableName;
if(sourceListId == 'firstList')
{
sourceTableName = "left_table";
destTableName = "right_table";
}
if(sourceListId == 'secondList')
{
sourceTableName = "right_table";
destTableName = "left_table";
}
for(i = sourceListBox.options.length-1; i>=0; i--)
{
//for() loop is used for finding how many options are selected.
if(sourceListBox.options[i].selected)
{
addOption(destListBox, sourceListBox.options[i].text, sourceListBox.options[i].value);
sourceListBox.options[i].selected = false;
AjaxRequest(sourceListBox.options[i].value,sourceListBox.options[i].text,sourceTableName,destTableName);
}
}
}
/**
* Calls to server through Ajax
* @param option value, option text, source table name and destination table name.
* @return none
*/
function AjaxRequest(i,textValue,sourceTableName,destTableName)
{
var url = '/run.php/SelectList'
var pars = 'cmd=singleTransfer' + '&itemValue=' + i + '&textValue=' + textValue + '&sourceTableName=' + sourceTableName + '&destTableName=' + destTableName;
var myAjax = new Ajax.Request(
url,
{
method: 'get',
parameters: pars,
onComplete: showResponse
}
);
}
function showResponse(originalRequest)
{
// CODE IN THIS FUNCTION DOES NOT ALWAYS EXECUTE.
}
Now i have solved the problem for the time being by making a single call to ajax for the whole loop. Now my question is : what is causing this problem? Can I give time delays between two consecutive requests?

I'm experiencing a weird problem when trying to do a $.ajax call. When I pass 5 variables, with either GET or POST, the script runs as I would like. However, when I use 6 or more variables, the script does not run. Does anyone know why this is?
Relevant code (stops1-5 are defined as JS variables earlier in my script, and the alerts are for testing)
$(".barcrawl-stop-id").each(function(){
alert("running ajax function");
$.ajax({
url: "/handlers/ajax/barcrawl_reorder.php",
[Code]....
So, the way it is now, it works fine (I get the first alert for each instance of .barcrawl-stop-id, and get an alert at the end with the returned data). However, when I add another variable to the data, like stop4: stop4, the script does not run (all I see is one alert with "running ajax function").

I am a newbie to using jquery and have been exploring it developing a new app. At the moment I have a number of AJAX calls to the server which I have been queueing in an array and using a single $.ajax call to handle all of them. However I know about the browser limitations of two calls per page (at the same time and want to implement this to speed up page updating). To test concurrent ajax requests I have setup various asp pages to with delays 1sec, 5sec, 10sec etc etc. and a test html file with the follwing javascript
