Fadein and Fadeout effect through javascript example
I suggest not to Jquery and Use following code for effect. This is very minimal code and you can very easily customize the CSS and javascript as per your requirement.
<html>
<head>
<style type="text/css">
.popup {
border: solid 1px #333;
font-family: Tahoma;
font-size: 12px;
display: none;
position: absolute;
width: 300px;
z-index: 60;
}
.popuptitle {
background: blue;
color: white;
font-weight: bold;
height: 15px;
padding: 5px;
}
.popupbody {
background: #ddd;
padding: 5px;
text-align: center;
}
#popup1 { top: 100px; left: 50px; }
#popup2 { top: 100px; left: 400px; }
</style>
<script type="text/javascript">
var fadeOpacity = new Array();
var fadeTimer = new Array();
var fadeInterval = 100; // milliseconds
function fade(o,d)
{
// o - Object to fade in or out.
// d - Display, true = fade in, false = fade out
var obj = document.getElementById(o);
if((fadeTimer[o])||(d&&obj.style.display!='block')||(!d&&obj.style.display=='block'))
{
if(fadeTimer[o])
clearInterval(fadeTimer[o]);
else
if(d) fadeOpacity[o] = 0;
else fadeOpacity[o] = 9;
obj.style.opacity = "."+fadeOpacity[o].toString();
obj.style.filter = "alpha(opacity="+fadeOpacity[o].toString()+"0)";
if(d)
{
obj.style.display = 'block';
fadeTimer[o] = setInterval('fadeAnimation("'+o+'",1);',fadeInterval);
}
else
fadeTimer[o] = setInterval('fadeAnimation("'+o+'",-1);',fadeInterval);
}
}
function fadeAnimation(o,i)
{
// o - o - Object to fade in or out.
// i - increment, 1 = Fade In
var obj = document.getElementById(o);
fadeOpacity[o] += i;
obj.style.opacity = "."+fadeOpacity[o].toString();
obj.style.filter = "alpha(opacity="+fadeOpacity[o].toString()+"0)";
if((fadeOpacity[o]=='9')|(fadeOpacity[o]=='0'))
{
if(fadeOpacity[o]=='0')
obj.style.display = 'none';
else
{
obj.style.opacity = "1";
obj.style.filter = "alpha(opacity=100)";
}
clearInterval(fadeTimer[o]);
delete(fadeTimer[o]);
delete(fadeTimer[o]);
delete(fadeOpacity[o]);
}
}
