Hi, how to activate the function?
I have sample:


 <script type="text/javascript" src="jquery.js"></script>
<script>
$(document).ready(function()
{
 //Paleidimo funkcija
 var time.ready(function()
  {
  $('#time_show').load('time.php?nu='+ Math.random());
  });
  });
</script> 
</head>                 
<body>
<?php
if($name == "Marrko") {run jquery time functions}
?>               
<div id="time_show"></div>

it would have to be something like this:


<body>
<?php
if($name == "Marrko") { ?>
 <script type="text/javascript">
  //do jquery stuff
 </script>
<? } ?>

then the problem is with the javascript. What is the code you're trying to run exactly? (the code that goes in the '//do jquery stuff' section from my example)

time_ref2 run fine(work), but stop function in time.php don't.


<html>                                 
<head>                                 
<script type="text/javascript" src="jquery.js"></script>
<script>$(document).ready(function(){
<?php
 $city = "Paris";
 if($city == "Paris"){ ?>
 var time_ref2 = setInterval(function()
    {
    $('#time_now').load('time.php?id='+ Math.random());
    }, 1000);
<?php } ?>
});
</script>
</head>                          <body>                           <div align="center" id="time_now">--:--:--</div>
</body>                          </html>

time.php:


<script type="text/javascript" src="jquery.js"></script>
<?php
$sec = date("s");
echo $sec;
?>
<script>$(document).ready(function(){
<?php
 if($sec == "30"){ ?>
 var stop = setInterval(function()
    {
    clearInterval(time_ref2);
    }, 2000);
<?php } ?>
});
</script>

ok it seems to me there are a few problems that need to be fixed, first I want to review what you're trying to do, let me know if this is correct:

1. once per second, load the contents of time.php and display them in the #time_now div
2. in time.php, get the current time in seconds and print it out. If seconds = 30, stop the interval on the parent page.

the problems I see are:

1. time.php doesn't know what time_ref2 is. time_ref2 was created on the parent page, so it doesn't exist on time.php
2. since time.php doesn't know what time_ref2 is, it can't stop the associated interval.
3. I'm not sure why you are setting an interval on the stop line anyway -- why not just clearInterval(time_ref2) without surrounding it in a setInterval?

Yes, you right.

But how this fix, sorry, i don't understand

I wouldn't bother trying to pass time_ref2 over to time.php

instead I would have some sort of a loop on the parent page that checks the contents of #time_now

something like:

if ( $('#time_now').html() == "30" ) {
// stop the interval
}

There are probably better ways to do it but off the top of my head that's what I'm thinking of first..
