Refresh with the help of countdown timer

**Sheravat** · 24-07-2010

Hi, I would like to develop a page (a kind of ticker), I, I'd like to see a script, with the browser, for example, after a minute, can automatically update the table!! I am trying to do lot of things but it is not happening.

. So thought that you guys must be knowing about it. How can I do it? Please help me as soon as possible. Any sample of the coding that can be useful for me, would be grateful.

The following script will definitely help you. Copy to clipboard (Internet Explorer only).

Code:

 <span><span style="direction: ltr; text-align: left" class="google-src-text">
$scheme = is_empty($_SERVER['HTTPS']) ?</span> $ Scheme = is_empty ($ _SERVER ['HTTPS'])?
</span> <span><span style="direction: ltr; text-align: left" class="google-src-text">'
http' : 'https';$server = $_SERVER['SERVER_NAME'];$path = $_SERVER['PHP_SELF'];
$query = $_SERVER['QUERY_STRING'];$url = "$scheme://$server/$path?$query";header("Refresh: 60; URL=$url");
</span> 'Http': 'https', $ server = $ _SERVER ['SERVER_NAME'], 
$ path = $ _SERVER ['PHP_SELF'], $ query = $ _SERVER ['QUERY_STRING'], 
$ url = scheme ": $ / / $ server / $ path? $ query "; header (" Refresh: 60; URL = $ url ");</span>

The below script is also made for am Internet Explorer.

Code:

 <span><span style="direction: ltr; text-align: left" class="google-src-text">
<html><head><script type="text/JavaScript">
var sec=60;function time_show(){sec=sec-1;document.getElementById('time_ad').innerHTML = sec;window.setTimeout("time_show()", 1000);}
</script></head><body onload="javaScript: time_show()">
<div id="time_ad"></div></body></html></span> <html> 
<head> <script type="text/JavaScript"> var sec = 60; 
time_show function () (sec = sec-1; document.getElementById ('time_ad'). innerHTML = sec; 
window.setTimeout (" time_show () ", 1000 );}</ script> </ head> 
<body onload="javaScript: time_show()"> <div id="time_ad"> </ div> 
</ body> </ html></span>

Script loads the first function, which then calls again after 1000 ms = 1s. to the variable load is counted down and is wrote in a div element ... clear?

Java script is as desirable, but comes from PHP-script out error message:

"Warning: Can not modify header information - headers already sent by (output started at C: \ Program Files \ xampp \ htdocs \ test.php: 7) in C: \ Program Files \ xampp \ htdocs \ test.php on line 22"

Why am I getting this error message?? Otherwise: "$ scheme = is_empty ($ _SERVER ['HTTPS'])? 'Http': 'https'," I have omitted, because the browser the following error message "Fatal error: Call to undefined function is_empty () in C: \ Program Files \ xampp \ htdocs \ berufsbot \ test.php on line 18" displays.

Instead of using only is_empty empty (unfortunately inconsistent created by the PHP programmers, perhaps, the last again or an alias). For header problem you find on Google or here in the forum and I am sure that you will get many solutions for this. Copy the script to clipboard of an Internet Explorer :

Code:

 <span><span style="direction: ltr; text-align: 
left" class="google-src-text">header("Location: http://google.com");
</span> header ("Location http://google.com:");</span>

Which must be spent in the HTML head, everything else is invalid HTML, and may well (at least in some browsers) problems.

Yeah, even I think that “Mecurtis” is correct. I am providing sample of coding, so that it would be easy for you to understand.

Code:

 java.text.DateFormat import;
 import java.text.SimpleDateFormat;
 import java.util.Date;
 import java.util.Timer;
 import java.util.TimerTask;
 import javax.swing.JFrame;
 import javax.swing.JLabel;
 public class Test extends JFrame (Timer
 / / Label to display the current time window
 private JLabel label = new JLabel ();
 Timer public Test () (
 / / Initialize window
 this.setSize (140.80);
 this.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);
 this.add (label);
 )
 public void start timer () (
 / / Create the timer  
 Timer t = new Timer ("Timer Thread", true);
 / / Create the timer task as inner class
 TimerTask task = new TimerTask () (
 public void run () (
 / / This is always executed when the timer strikes:
 / / We write in the current time window
 DateFormat format = new SimpleDateFormat ("hh: mm: ss");
 setText (format.format (new Date ()));
 )
 );
 / / Start the timer immediately interval 1000ms
 t.schedule (task, 0, 1000); 
 )
 public void setText (String text) (
 / / Sets the text in the window and return it to the console also
 label.setText (text);
 System.out.println (text);
 this.validate ();
 )
 public static void main (String [] argv) (
 / / Main method: Creates the window and starts timer
 Test Test Timer timer = new Timer Test ();
 timerTest.setVisible (true);
 timerTest.startTimer ();
 )
 )
