JavaScript - Refresh Problem

Hi,

I have the below code:
Code:

<script type="text/javascript">
function loadQuickMessageCheck(File,ID){

var xmlhttp; 

if (window.XMLHttpRequest)  {
  xmlhttp=new XMLHttpRequest();
  }
else {
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }

xmlhttp.onreadystatechange=function(){
  if (xmlhttp.readyState==4 && xmlhttp.status==200){
    document.getElementById(ID).innerHTML=xmlhttp.responseText;
	 eucalyptus = setInterval(function(){loadQuickMessageCheck(File,ID)},20000);
    }
  }

xmlhttp.open("POST",File,true);
xmlhttp.send();
}
</script>

But I am overloading the server and crashing it. I've googled the issue and have found people with similar problems who talk about the need to cancel the last refresh request before they send the next refresh.

I even found this nice piece of code which worked for someone else.
Quote:

try{window.clearTimeout(tRefresh)} catch(err) {}
tRefresh = setInterval(setContext, varInterval*60*1000);
}
I am not sure if this is the solution that I am looking for but if it is all my attempts at applying this code has been a bit of a disaster.

Hi

I need some help. I have a link that opens in a new window which allows the user to perform an update to a record. On submit I want it to obviously update (which it does), then close the page and update the main page (where we opened the link from initially).

I seem to have this working using an function which is called off the submit button using onclick........the function is:

<script type="text/javascript">
function windowclose() {
window.opener.location.href = window.opener.location.href;
window.close()
}
</script>


Now, the update happens as I say, and the page closes, and the main page looks like it refreshes but the update is not reflected....if I hit f5 the update appears. Is it to do with the speed of writing to the database and updating the screen? I have also been playing around with trying to add a settimeout to add a delay between update and close/refresh but couldnt get it to work.

Any help would be appreciated.

Cheers!

Okay, so I'm making something so IF the number is BETWEEN this number, and that number, I want it to display a certain number.

Ex.
Code:

var Num1 = 100
var Num2 = 200
var Num3 = 1

If (Num1{THIS IS WHAT I DON'T KNOW}Num2)
{
alert(Num3)
}

Also, could somebody please tell me what those are called?
The;
==
!=
||
etc.
Because I was having a TERRIBLE time trying to google that. AHH!

I'm sorry for this. I know this is a stupid question.

Okay, I assume many will think I must have missed the previous thread, but I did look at it, and I am not sure if that one comes close to answering my idea here.

I was looking at NHL.com, and I noticed the scoreboard changed without me reloading the page. So... I looked at the code, and this is where I got completely lost: Code:

<div id="scoreboard">				
					<style type="text/css">
    #masthead #richMedia, #scoreboard { margin-left: 0px; width: 817px; }
</style> <script src="/js/hdr_scoreboard.js?v=6" language="JavaScript" type="text/javascript"></script>  <script language="JavaScript" type="text/javascript">
    var dataSource = "http://live.nhle.com/GameData/PlayoffScoreboard.jsonp?loadScoreboard=?";    
    jQuery(document).ready(function() { initScoreboard(5, 'cc0000', '000000'); });
</script>

What I am interested in doing is reloading an iframe that has a total visitor counter. That way say every 5 minutes or so, it gets updated without any interaction needed.

I tried the meta refresh on the iframe's target page long ago, but that forced a reload on the main page as well, and I am totally against doing that.

So, does anyone here have any tips to provide?

Here is my calander script

what would be the best way to make it so that if you wish to chnage the month it changed the month on page rather than refresh the whole page its on?

Hi there, I'm working on a presentation and I'm going to store each page into a ".html"

So in example, I have...
"1.html"
"2.html"
"3.html"

Each number goes to each slide accordingly.

The way I was working the presentation out was having users load a webpage via mobile phone which contains an iframe. I'll change the src of the iframe to the desired slide; and the META refresh will handle displaying it to the user.

Now, here's the problem. It flashes on some browsers, like Blackberries.

I'd like for the content being refreshed to not flash, but appear naturally. That way, the user doesn't have to attempt to read flashing text (which gets -REALLY annoying)
------------------------------------
TLDR; I need some code to refresh a page/div without flashing the content on ALL if not MOST browsers. Thanks.
------------------------------------
I think I know how I'd solve this issue; but I'm not too sure how to "integrate it"

Perhaps, have a Javascript code keep the current "look" of the page static until "X" seconds. So, this would happen.

Page refresh -> Javascript holds page for 5 seconds -> Page finishes loading -> Original page revealed

It'd act kind of like a cover-up.

Hi,

I have an onclick handler as:

onClick="window.open ('test.cgi?action=testfile', 'testframe')"

When clicked on the button for the first time, request is sent to webserver and target file for "testfile" action is getting loaded in frame testframe.
But when i click for the second time, request is not sent to webserver and the cached entry is getting loaded.

This issue is occuring only in IE but not in FF.
I went to the cached data in
c:\Documents and settings\<user>\...\Temporary Internet Files\
and i'm seeing that targetfile for test.cgi?action=testfile is getting stored and
"last accessed" time stamp is updated but the "last checked" value is not getting updated (when ever i click on the button).


But no issue is seen when the onclick handler is like below:
onClick="document.location='test.cgi?action=testfile'


I could not understand what exactly is the issue:
Is it with Frames/window.open/Do i have to remove cached entries? etc...

Can any one please help me out on how i can proceed with this...
Please let me know if i'm not clear with above description. Thanks in advance...

I am trying to submit a hidden text area from a WYSIWYG editor. Its submitting the subject line which is a standard text input but its not submitting the text area. I can only think its because there are html tags in the submitted data.

Is there a way to compensate for this or will I have to give up trying.

Well first off all I would appricate any help that you could give me because I've been looking all over the internet for the solution without any result.

So off to my problem, I made this text-based online game and let's say the user does a crime, he did this crime 17:04:30 and has to wait till 17:06:30 before he can do a crime again (this is printed in the MySQL database).
Getting the value from the database and changing it into the right format mm:ss is no problem. The problem comes to when its about refreshing... I've tried meta refresh and javascript location.refresh with good results, i sat the timer to 1 sec and it refreshed.
The problem comes to when it refresh the mouse cursor and the tab (in firefox and chrome) gets that look, like when u refresh a page normally u can see an hourglass and all that. Is there anyway to disable that? And i think it really slows the browser down after a while (because after like 30 min or more firefox used 600 mb of my RAM).

So yeah here's my Iframe code:

Code:

print <<<ENDHTML
<IFrame Src= "right_timer.php" Scrolling=No Frameborder=0 
Marginheight=0 Marginwidth=0 Width=100% Height=160> 
  <p>Your browser does not support iframes.</p>
</iframe>

Also here's the right_timer.php:

Code:

<?php
  include("config.php");
  $dbres = mysql_query("SELECT *,UNIX_TIMESTAMP(`crime`) AS `crime` FROM `users` WHERE `login`='{$_SESSION['login']}'");
  $data	= mysql_fetch_object($dbres);  
  if(! check_login()) {
    print"<link rel=stylesheet type=text/css href=style.css>";exit;
  }
if ($data->status == dead) { print"<link rel=stylesheet type=text/css href=style.css>";exit; }
?>
<html>
  <head>
    <meta http-equiv="refresh" content="1">
  </head>
<body>
<?php
$dbres = mysql_query("SELECT * FROM `users` WHERE `activated`='1'");
$users= mysql_num_rows($dbres);
$dbres = mysql_query("SELECT * FROM `users` WHERE `status`='alive' AND `activated`='1'");
$levend = mysql_num_rows($dbres);
$dbres = mysql_query("SELECT * FROM `users` WHERE  UNIX_TIMESTAMP(NOW())-UNIX_TIMESTAMP(`online`) < 300");
$online = mysql_num_rows($dbres);

$dbres = mysql_query("SELECT * FROM `users`");
while($blah = mysql_fetch_object($dbres)){
$time = time();
$crime = gmdate('i:s',($data->crime - $time));
if (($data->crime - $time) < 0) { $crime = Now; }
}
print <<<ENDHTML
<tr><td>Crime {$crime}</td></tr>
ENDHTML;
?>
</body>
</html>

Whenever I update my website, sometimes I notice my browser shows the old version or a modification in the browser after I upload to the ftp.

Whats the best way to prevent this from happening? Preferably without noticing it happening.

Thanks.

i have a page named pck_rates.php which contains a form that go to the page update_pck_rates.php

when i press updade data button in the second page i want the first page to be refreshed to show the new data's.


i want to know if i can set a name to the page pck_rates.php and after the update query in the second page i will refresh the pck_rates.php page using this name??

i don't know what is the function and how to make this idea.
can anyone help me please

This works on one of our other sites, but today I noticed this site is having a problem, its just not refreshing at all... here is the code..

(what is used on the iframe)
Code:

<iframe id="ad1"

whats in the header (besides the including of the js file)
Code:

<script type="text/javascript">
var imageIntervals={};
var imageLimit={};
var imageCount={};
</script>

and the actual script
Code:

function toggleImage(id) {if(imageCount[id]<imageLimit[id]||imageLimit[id]<0) {var img=document.getElementById(id);img.src=img.src;imageCount[id]++;}else {clearInterval(imageIntervals[id]);}}
function setImageInterval(id, ms, limit) {imageIntervals[id]=setInterval("toggleImage('"+id+"')", ms);imageLimit[id]=(limit!==undefined?limit:-1);imageCount[id]=0;}
/* IFERAME RATES */
window.onload=function() {
    setImageInterval("ad1", 72000, 4);
    setImageInterval("ad2", 60000, 4);
    setImageInterval("ad3", 66000, 4);
    setImageInterval("ad4", 72000, 4);
    setImageInterval("ad5", 72000, 4);
    setImageInterval("ad6", 76000, 4);
}

This should work, but its not so trying to see if you can see something I dont. If theres a better iframe refresh script out there that can do different intervals, please share. Thanks

Is there any chance i can add a refresh timer to this?

hi

i have a table with some document.write statements inside that write inside the cells.

i need to refresh the table from a function so the statements will execute again. but i only want the table to refresh not the whole page

document.location.reload()
this does the page but can i put the tables id in the brackets or something.

thanks

Hi to all,

I got a timestamp (in the future) and I want to display on a page how many seconds this differs from now. I know how to do this in PHP, but now it's static, I want it to actually count down.
After the countdown, the page should be refreshed, although I could also do this with a meta tag, as I can just find the value with PHP on load and put that value in a meta refresh tag.

Could you help me out with one of these things?
