Hello Friends,
If you want to know how to refreshing parent widow from child small window. so first you create JavaScript function in child window page and in function for example :-
<script language="javascript">
function par_refresh()
{
window.close();
if (window.opener && !window.opener.closed) {
window.opener.location.reload();
}
}
</script>
then use this function on child close button for example:-
<input onclick="par_refresh()" type="button" value="Close" />
And if you want go another url in parent main window from child small window so here is code below..
<script language="javascript"> var randomnumber=Math.floor(Math.random()*11); parent.opener.location.href='another page url?sid='+randomnumber; parent.close(); </script>
So here you can easily refresh and redirect your parent window through this code..

Hello Friends,
Welcome in Codehunter.in for html tutorial. here you will learn how to use html for creaing your own website.
HTML, which stands for HyperText Markup Language, is a markup language used to create web pages. The web developer uses “HTML tags” to format different parts of the document. For example, you use HTML tags to specify headings, paragraphs, lists, tables, images and much more.
HTML is a subset of Standard Generalized Markup Language (SGML) and is specified by the World Wide Web Consortium (W3C).
What do I need to create HTML?
You have everything to create html page.
1. Computer
2. Text-editor or html editor
3. Web browser
HTML Tags
HTML markup tags are usually called HTML tags
- HTML tags are keywords surrounded by angle brackets like
- HTML tags normally come in pairs like and
- The first tag in a pair is the start tag, the second tag is the end tag
- Start and end tags are also called opening tags and closing tags
HTML Documents = Web Pages
- HTML documents describe web pages
- HTML documents contain HTML tags and plain text
- HTML documents are also called web pages
So here you can start with first example
<html> <body> <h1>First Heading</h1> <p>first paragraph.</p> </body> </html>
- Starting tag and ending tag between this text describes the web page.
- The text between and is the visible page content
- The text between and is displayed as a heading
- The text between and is displayed as a paragraph save this page like pagename.html and open it in your browser

Simple Dynamic Ajax Agent Paging
Posted on November 30, 2009
Filed Under Ajax | 5 Comments
Hello Friends,
Here I give you simple dynamic paging using ajax agent…
First you create config.php like this…
<?php
$host="localhost"; // Replace with your host name
$username="root"; // Replace with your username
$password=""; // Replace with your Password
$con=mysql_connect($host,$username,$password);
mysql_select_db("paging",$con);
?>
Create Database name paging like this :-
CREATE TABLE `user` ( `id` int(11) NOT NULL auto_increment, `fname` varchar(255) NOT NULL, `lname` varchar(255) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=7 ; INSERT INTO `user` (`id`, `fname`, `lname`) VALUES (1, 'balraj', 'parmar'), (2, 'amit', 'paliwal'), (3, 'rahul', 'khanna'), (4, 'raj', 'parmar'), (5, 'raju', 'parmar'), (6, 'ritesh', 'parmar');
Here your index.php page..
<?php
//database connection file config.php....
include("config.php");
// Ajax Agent use for paging
include_once("ajax/agent.php");

/**
* Converts to and from JSON format.
*
* JSON (JavaScript Object Notation) is a lightweight data-interchange
* format. It is easy for humans to read and write. It is easy for machines
* to parse and generate. It is based on a subset of the JavaScript
* Programming Language, Standard ECMA-262 3rd Edition - December 1999.
* This feature can also be found in Python. JSON is a text format that is
* completely language independent but uses conventions that are familiar
* to programmers of the C-family of languages, including C, C++, C#, Java,
* JavaScript, Perl, TCL, and many others. These properties make JSON an
* ideal data-interchange language.
*
* This package provides a simple encoder and decoder for JSON notation. It
* is intended for use with client-side Javascript applications that make
* use of HTTPRequest to perform server communication functions - data can
* be encoded into JSON notation for use in a client-side javascript, or
* decoded from incoming Javascript requests. JSON format is native to
* Javascript, and can be directly eval()'ed with no further parsing
* overhead
*
* All strings should be in ASCII or UTF-8 format!
