JavaScript is a programmable API that allows cross-platform scripting of events, objects, and actions. It allows the page designer to access events such as startups, exits, and users' mouse clicks. JavaScript extends the programmatic capabilities of most browsers to a wide range of authors, and is easy enough for anyone who can compose HTML.
Using JavaScript, even less-experienced developers will be able to direct responses from a variety of events, objects, and actions. It provides anyone who can compose HTML with the ability to change images and play different sounds in response to specified events, such as a users' mouse click or screen exit and entry.

To create a single line comment in JavaScript, you place two slashes "//" in front of the code or text you wish to have the JavaScript interpreter ignore. When you place these two slashes, all text to the right of them will be ignored, until the next line.

Hi,

Thanks for the info...

Here's my sample javascripts...

Create a welcome cookie

<html>
<head>
<script type="text/javascript">
function getCookie(c_name)
{
if (document.cookie.length>0)
{
c_start=document.cookie.indexOf(c_name + "=");
if (c_start!=-1)
{
c_start=c_start + c_name.length+1 ;
c_end=document.cookie.indexOf(";",c_start);
if (c_end==-1) c_end=document.cookie.length
return unescape(document.cookie.substring(c_start,c_end)) ;
}
}
return ""
}

function setCookie(c_name,value,expiredays)
{
var exdate=new Date();
exdate.setDate(exdate.getDate()+expiredays);
document.cookie=c_name+ "=" +escape(value)+((expiredays==null) ? "" : "; expires="+exdate.toGMTString());
}

function checkCookie()
{
username=getCookie('username');
if (username!=null && username!="")
{
alert('Welcome again '+username+'!');
}
else
{
username=prompt('Please enter your name:',"");
if (username!=null && username!="")
{
setCookie('username',username,365);
}
}
}
</script>
</head>
<body onLoad="checkCookie()">
</body>
</html>

A clock created with a timing event

<html>
<head>
<script type="text/javascript">
function startTime()
{
var today=new Date();
var h=today.getHours();
var m=today.getMinutes();
var s=today.getSeconds();
// add a zero in front of numbers<10
m=checkTime(m);
s=checkTime(s);
document.getElementById('txt').innerHTML=h+":"+m+" :"+s;
t=setTimeout('startTime()',500);
}

function checkTime(i)
{
if (i<10)
{
i="0" + i;
}
return i;
}
</script>
</head>

<body onload="startTime()">
<div id="txt"></div>
</body>
</html>

Style strings

<html>
<body>

<script type="text/javascript">

var txt="Hello World!";

document.write("<p>Big: " + txt.big() + "</p>");
document.write("<p>Small: " + txt.small() + "</p>");

document.write("<p>Bold: " + txt.bold() + "</p>");
document.write("<p>Italic: " + txt.italics() + "</p>");

document.write("<p>Blink: " + txt.blink() + " (does not work in IE)</p>");
document.write("<p>Fixed: " + txt.fixed() + "</p>");
document.write("<p>Strike: " + txt.strike() + "</p>");

document.write("<p>Fontcolor: " + txt.fontcolor("Red") + "</p>");
document.write("<p>Fontsize: " + txt.fontsize(16) + "</p>");

document.write("<p>Lowercase: " + txt.toLowerCase() + "</p>");
document.write("<p>Uppercase: " + txt.toUpperCase() + "</p>");

document.write("<p>Subscript: " + txt.sub() + "</p>");
document.write("<p>Superscript: " + txt.sup() + "</p>");

document.write("<p>Link: " + txt.link("http://www.w3schools.com") + "</p>");
</script>
