Synchronizing Multiple AJAX Calls In Window.onload() Event

May 18, 2007

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....?

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)

JQuery :: Multiple Parallel Ajax Calls - Improving Performance?

Apr 23, 2010

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?

JQuery :: Prevent Multiple AJAX Calls From Button/link Push?

Sep 28, 2010

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.

Multiple Onload Event - Utilize Two Separate Onloads Events

Aug 10, 2009

I am new to Javascript and am trying to add some functionality to a website but have come across a problem when trying to utilise two seperate Javascript onloads events. I have a text scroller to display the latest news and I also have a javascript lightbox gallery. Both of these events work perfectly on their own but when I try to include both on one page only one of the events is executed. My code is displayed below:

<script type="text/javascript" src="js/prototype.js"></script>
<script type="text/javascript" src="js/scriptaculous.js?load=effects,builder"></script>
<script type="text/javascript" src="js/lightbox.js"></script>
<script type="text/javascript" src="js/jquery-1.2.6.pack.js"></script>
<script type="text/javascript" src="js/jquery.li-scroller.1.0.js"></script>

Access A Remote Window's Onload Event?

Dec 7, 2009

If I use a window opener to open a new window, is there a way to detect that the new window is finished loading before carrying out some other directive in the opener window? Can I access the remote window's onload event from the opener window? I need to know that the website has loaded before moving to the next page. something like:

remoteWindow.onload = goToPage(url);

IE Losing Onload Event After Ajax Request

Jun 21, 2006

I'm having a problem on a site where an onload event works in Firefox but not in IE. Actually, the onload event works in IE once - but then if the Ajax onreadystatechange changes, IE chokes and doesn't use the onsubmit event that worked when the page first loaded. Code:

Try entering something that isn't an email address and submitting it. Then try just submitting a blank form. Firefox will do the asynchronous call to a PHP script and return the results - IE will do it the first time, and then not again. Code:

IE works fine if I add a simple 'onsubmit="saveData();"' to the form itself, but I'm trying to keep my semantic, presentation, and behavioural layers separate. Using the DOM seems to be the way to do that, but IE seems to only do an XMLHttpRequest once and then stop listening for the event.

Pass A PHP Variable To A Window.onload Event Function?

Dec 21, 2009

How do I pass a PHP variable into a window.onload event function? I have a URL that I need to pass to the JavaScript file that has this function in it. The JavaScript file itself is being linked from the PHP file that will pass the variable and I've seen many examples of how this is done via embedded JavaScript, but none where someone is linking to an external JavaScript file. I suppose this is probably a trivial matter to most of you, but I've never done this before and could use some guidance!

IE Can Not Handle Multiple "window.onload" Which Causes Only The First Image To Slowly Fade In?

Mar 6, 2011

HI'm working on a website and i was asked to add a fancy fade in effect which after a ton of scourcing the web i managed to find and get to work

function fadein(){var fade=0,
fadein=document.getElementById("Astuces").style,ms=(fadein.opacity==0)?0:1,
pace=setInterval(Fade,30);[code]....

Now for the index page there are multiple images that i want to have fade in one after another. What i did was copy the above code a 5 times and change the function names. It worked like a charm in both Chrome and Firefox however IE as usual is being a partypooper. it appears that IE does can not handle multiple "window.onload" which causes only the first image to slowly fade in.Here is my current code, how can i make it IE competable?

function fadein(){var fade=0,
fadein=document.getElementById("Astuces").style,ms=(fadein.opacity==0)?0:1,
pace=setInterval(Fade,30);[code]....

Which Loads Faster, Body Onload Or Window.onload

Dec 3, 2005

I wander what gets loaded the fastest (1-2 or 3) in what succession:

<head>
<script type="text/javascript">
function andAction() {
// doing stuff
}
</script>
</head>

<body onload="andAction();">
<script type="text/javascript">andAction()</script></body>

just in the head and nothing more

This I am sure off:

<head>
<script type="text/javascript">
window.onload = function andAction() {
// doing stuff
}
</script>
</head>
<script type="text/javascript">andAction()</script></body>

just in the head and nothing more (should be 1)

Third and last which is faster:

body onload or window.onload

AJAX :: Functions Never Work With PHP - Tree Folder Which Calls Another Page To Be Loaded Into A DIV By AJAX Again

Apr 14, 2009

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?

Window.onload And Body.onload Differences

Jul 23, 2005

I'm seeing a difference in behaviour between

window.onload = f();

and

<body onload="f();">

Specifically, window.onload appears to fire before all the elements of
the page have been rendered. As the difference is consistent across
IE/Moz/Opera, I'm assuming it's deliberate - can anyone point me
towards where this behaviour of window.onload is defined in the
documentation? TIA. Code:

AJAX :: Update Multiple Window Elements With Single Request?

Dec 18, 2010

The general outline is that I have part of a page that deals with the addition, editing and deletion of upcoming events. Data is stored in a MySQL table. The form design (in traditional terms) would be very simple requiring three fields, one for the Event Name, one for the Event Description and one (hidden) to identify the UniqueID of the event in the MySQL table. (As the reference to make edits.) The table therefore has 3 fields. (There are more such as Timestamp, clientID etc, but they are not important here.)

I envisage three functions, one to add, one to edit and one to delete the event listed on the page. I have 3 php files eventadd.php, eventedit.php and eventdelete.php which speak for themselves.However, this is where I have the problem. What I have been doing is returning the xmlhttpresponse as a formatted HTML page for the two 'form' elements because whilst I can return unformatted text containing the relevant fields in one response, I don't know how to break that down into two sections for the innerHTML of the two 'form' elements that change.

Returning a formatted page does work, but as well as being slower than neccessary, I am also running into character-set encoding issues and I just know that I am not doing this properly. I can supply code and things, but I have a feeling that this problem will have come up somewhere and probably has a recognized solution because to me it seems to be such an obvious requirement to be able to populate several form elements with fields from one recordset.

Adjusting Function For Multiple Calls?

Oct 17, 2010

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.

Handling Multiple Xmlhttp Calls.

Feb 26, 2006

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.

Multiple Function Calls From A Single Js File

Dec 11, 2007

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.
