JavaScript - Run A Php Script Without Slowing Down Page-load

Hi all

Is there a way to get the image(s) to load into the table after the page has loaded instead of the way I have it now?

I have 4 tabs, but I would like the imgs in tabs 2,3,4 to load after page load.

Example of how the tabs look.

Code:

    	  <div class="tabbertab">
            <h2>Australia_____</h2>
                      <table width="100%" border="0" cellpadding="3" cellspacing="1" bgcolor="#FFFFCC">
                       <caption class="highlight_Red">澳洲&nbsp; Australia
                       </caption>
  <tr>
    <td><a href="pages/promotion.html#aus_ACE" rel="nofollow" target="_blank"><img src="pages/images/Pics/AUS/ace.jpg" alt="ACE / ATTC" width="110" height="69" border="0" align="left" class="ozimg_L"/> ...a few more images etc

the other tabs look the same.

This script displays a link to a registration/login form that loads in a light box for Joomla.
I've been goin nuts trying to figure out how to get this to load on page load with a delay.
Anyone know how to get this done?
PHP Code:
<?php
JHTML::_('behavior.mootools');
$document = JFactory::getDocument();
$document->addStyleSheet(JURI::base() . 'media/system/css/modal.css');
$document->addScript(JURI::base() . 'media/system/js/modal.js');
$document->addScriptDeclaration("window.addEvent('domready', function() {SqueezeBox.initialize({});});");
$user = & JFactory::getUser();

$uri = JFactory::getURI();
$url = $uri->toString();
$return = base64_encode($url);

?>
<div id="lbframeid" style="position:absolute;top:1px;left:1px;height:0px;width:0px;overflow:hidden">
<a href="http://www.wowjoomla.com/"><h1>Joomla Login LightBox powered by WowJoomla.com</h1> </a>
</div>
<?php if ($user->get('guest')) :?>
   <a href="<?php echo JRoute::_('index.php?option=com_loginbox')?>" 
      onclick="SqueezeBox.fromElement(this); return false;"  
      rel="{handler: 'iframe', size: {x: 660, y: 500}}"><?php echo JText::_('SIGNUP_LOGIN')?></a>
   <?php else: ?>
<?php echo JText::sprintf( 'HINAME', $user->get('name') ); ?>
<br>
   <a href="javascript:void(0);" onclick="LB_onLogout(); return false;"><?php echo JText::_('LOGOUT')?></a>
<?php endif; ?>
<script type="text/javascript">
function LB_onLogout() {
   var form = new Element('form');
   form.setProperty('method', 'POST');
   form.setProperty('target', '_self');
   form.setProperty('action', 'index.php');
   
   var input = new Element('input');
   input.setProperty('type', 'hidden');
   input.setProperty('name', 'option');
   input.setProperty('value', 'com_user');
   form.appendChild(input);

   $E('body').appendChild(form);
   form.submit();
}

I've written some code to execute a loop. It's all standard stuff using a for loop but the problem I have is that it is executed too quickly.

Between each iteration of the loop I want to insert a "pause" of, say, 40 or 50 milliseconds. I initially tried the setTimeout() function but I soon found out that wasn't right for use within a loop. What I want to achieve could be summed up as follows:-

for (i = 1; i <= 100; i++)
{
dosomecode();
wait(50);
}

I've spent some time looking into this but couldn't get anything to work. If you haven't already guessed, I'm quite new to Javascript and any help would be appreciated.

Dear readers,

Context:
I have a dedicated GPS tracker that records every 3 seconds my location.

What I want to do:
Find the country, postal code, province, street and place from every coordinate.

What my codes (javascript) does so far:
- Create tables and inserts the coordinates into the table
- Retrieves the country, streets etc from google with geocoder.geocode
- Updates the tables with country, street etc.

What is my problem:
The first 1-50 retrieves is going quick, after that it slows down and after about 300 retrieves it is very slowwwwwwwwww. When I refresh my html page and start over, it is again quick to retrieve the data but will slow down again.

I am using a time-out so that I am retrieving no more that 1 coordinate per 2-3 seconds. Because after I refresh the page and start directly over again, I do not think it is the limitations of retrieving from Google. I also canceled the writing to the database and only showing in the console the results and that is slowing down also after a few retrieves (so I think it is not a database problem).

I am not a programmer and my code will probably not be 'clean'. I could realy need some help with this. I could send you my code so that you can try it yourself. I am using Chrome version 39.0.2171.95 m

Maybe the problem is that you are doing more timeout() calls than you think. Simple but horrible example: Suppose that every time you retrieve the data from the geocoder you set a timeout for the next retrieval. And then every time you fill in the tables, you *also* set a timeout for the next retrieval.

That means that on the 2nd retrieval you will end up doing *FOUR* timeouts. And every 3 seconds you will be doubling the number of retrievals you do.

Now clearly if you were really doing the above you would slow down horribly within 20 or 30 seconds. But suppose it is something more subtle than that, where you only do an extra timeout under certain conditions. That could very well explain it.

That's not the only possible explanation, but it's where I would start. Maybe start logging the time, to the millisecond, of each retrieval...and see how many retrievals you are doing and how often. For that matter, just dump those numbers to the screen to see what they look like.

Hello. My goal is to load the JS for a specific element before displaying that element. I integrated a third part script, and it works well. I set the timer he

The JS is in my heading as <script type="text/javascript" src="countdownpro.js"></script>

About mid-body I have: <span id="countdown1">2010-07-20 00:00:00 GMT+00:00</span> which allows for the setting of a target date to countdown to.

When the page first loads it shows the above long format target time, until the js/meta tags kick in to modify it to just show the actual countdown as 00:00:00.

I have attached countdownpro.js to this post. I tried shifting the function CD_Init() to the top of the script, and also appended it inline with the .html. I tried setting the big external script to "defer", but neither arrangement worked. I also tried placing the src file right at the top.

I appreciate your help.

Hi All,
Im new to this forum...need some of your help and advice.

I have a js code like this :

<script type="text/javascript">
<!--
var sipPos = 0;
$(document).ready(function() {

$("#panel-tab").click(function(e) {
//if(autoTimer) clearTimeout(autoTimer);
//autoTimer = null;
e.preventDefault();
$("#panel").animate({ left: sipPos }, 1764, 'linear', function() {
if(sipPos == 0) { sipPos = -856; }
else { sipPos = 0; }

});
});
});
-->
</script>

what it does is that it hide and show a panel by slidint it to the left.

But my client want that on page load the panel opens automatically for about 2-3 seconds just to let users know that its here. So ive written this :

<script type="text/javascript">
<!--
var sipPos = 0;
$(document).ready(function() {
var autoTimer = null;
autoTimer = setTimeout(function(){
$("#panel").animate({ left: sipPos });
autoTimer = setTimeout(function(){
$("#panel").animate({ left: sipPos = -856 });
}, 2000);
},1000);

$("#panel-tab").click(function(e) {
//if(autoTimer) clearTimeout(autoTimer);
//autoTimer = null;
e.preventDefault();
$("#panel").animate({ left: sipPos }, 1764, 'linear', function() {
if(sipPos == 0) { sipPos = -856; }
else { sipPos = 0; }

});
});
});
-->
</script>

But when the panel finished showing the button to open it again doesn't work...any help please..really urgent.

I want this script to load after the page load
the script is:
Code:

<script type="text/javascript" src="http://localtimes.info/clock.php?cp3_Hex=0F0200&cp2_Hex=FFFFFF&cp1_Hex=000080&fwdt=118&ham=0&hbg=0&hfg=0&sid=&mon=&wek=&wkf=&sep=&continent=Asia&country=Indonesia&city=Jakarta&widget_number=116"></script>

the script in My page is like:
Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>My test page</title>
</head>

<body>
<h1>Tony</h1>
<h2>Welcome Tony Website</h2>
<script type="text/javascript" src="http://localtimes.info/clock.php?cp3_Hex=0F0200&cp2_Hex=FFFFFF&cp1_Hex=000080&fwdt=118&ham=0&hbg=0&hfg=0&sid=&mon=&wek=&wkf=&sep=&continent=Asia&country=Indonesia&city=Jakarta&widget_number=116"></script>
<h3>Tony is ... and is....</h3>
<h3>He will....</h3>
</body>

</html>

So how can I make this script loads after all elements of My page are loaded and without changing it's position (the script position)?

Hello,
Well I have script that claims that it loads the flash content while it is showing seconds or advertisement. So as I don't know about scripts I have no Idea if it actually do that or not as What I visually see is that it let flash content load once the seconds of disappears. So that's why I want an expert advice on it.
And how the seconds of this script works Only if this script actually do what It claims, then I would like to know when does it send alert to load the content (as I would like to put the alert from the start) and how to show it for more or less seconds.

Hello

Basically I have found and adapted the code:

Code:

alreadyloading = false;
nextpage = 2;
 
$(window).scroll(function() {
    if ($('body').height() <= ($(window).height() + $(window).scrollTop())) {
        if (alreadyloading == false) {
            var url = "page"+nextpage+".html";
            alreadyloading = true;
            $.post(url, function(data) {
                $('#projectscontainer').children().last().after(data);
                alreadyloading = false;
                nextpage++;
            });
        }
    }
});

I want when the user scrolls to the bottom of the page for content in a new page to load under the div "#projectscontainer". So in the new page 'Page2.html" I have put 5 divs going down with content in...

I want the new content to appear below "#projectscontainer'"

Why won't this work? Anyone know?

Thanks

Thankyou

I am trying to make the following fill the value box when the page loads as opposed to pressing the button. I cant seem to do it. Any ideas??

PHP Code:
<script>
var keylist="abcdefghijklmnopqrstuvwxyz123456789"
var temp=''

function generatepass(plength){
temp=''
for (i=0;i<plength;i++)
temp+=keylist.charAt(Math.floor(Math.random()*keylist.length))
return temp
}

function populateform(enterlength){
document.pgenerate.output.value=generatepass(enterlength)
}
</script>

<form name="pgenerate">
<input type="text" size=18 name="output">
<input type="button" value="Generate Password" onClick="populateform(this.form.thelength.value)"><br />
<b>Password Length:</b> <input type="text" name="thelength" size=3 value="7">
</form> 

Any help would be greatly appreciated...

I'm trying to get cross-browser column support working using the "css3-multi-column.js" script included in the following tutorial:

http://www.cvwdesign.com/txp/article/360

The javascript works, making columns when the site is loaded in Firefox but I keep getting "access denied" errors for the ""css3-multi-column.js" script in Internet Explorer 8, resulting in no columns. I tested the tutorial's example in IE 8 (worked fine), then referred to the tutorial's example time and again checking for discrepancies but I can't seem to figure out where I'm going wrong.

Here's an example on my site where columns are to appear:

Thanks once again.

How do I make my Script load faster?

Is there Code that will make my Script load faster,
(so that it won't take so long to view)

If so, can someone show me how to incorporate it into my Example Script?

With appreciation

Hi,

Im trying to load a remote script but only if a statement is true..

Code:

<script type="text/javascript">
var width=screen.width;
if (width>1023);
{
// load remote script
}
</script>

How would I go about this? And will it work if the script in php?

Thank youu!

EDIT: I realise its probably not the best practice but at the moment im having to use

Code:

<script language="javascript">
window.location.href = "index2.php?width=" + screen.width;
</script>

and on index2.php
Code:

<?php
$res=$_GET['width'];
if ($res > 1024) {
include("header.php");
}
?>

Hey guys,
I've just started with javascript so please, be gentle

I am making a wordpress plug-in which puts a banner-rotator on the front page which is able to load both images and flvs'.

It has a carousel menuand the images/objects are loaded as you hover over the thumbnails.

I have made an js array in a php loop so that every element of the menu list gets assigned a different onMouseOver function when it is generated.

Because I was not able to change FlashVars with js I have put the whole object embed code in one variable and insert that in a div with innerHTML when mouseOver.

This works fine in firefox but not at all in any other browsers!!

What can I do?

The website is located at: www.mediapod.org/jwp

Here is the code:
Code:

function wp_main_player() {
global $wpdb;
$noChartsID = $wpdb->get_col($wpdb->prepare("SELECT * FROM wp_term_relationships WHERE term_taxonomy_id = 5"));
