Hi guys,
A snippet on making a span invisible with fading effect.
<html xmlns=”http://www.w3.org/1999/xhtml” ><head > <title>Making Div Opaque</title><script type=”text/javascript” >var firstClick = true;function opacity(myID) {
if(firstClick){var millisec = 500;//speed for each frame var speed = Math.round(millisec / 100); var timer = 0; for(var i = 100; i >= 0; i–) {setTimeout(
“changeOpac(“ + i + “,’” + myID + “‘)”,(timer * speed)); timer++;if(i==0){firstClick = false;}}}
}
//change the opacity for different browsersfunction changeOpac(myopacity, theID){var object = document.getElementById(theID).style; object.opacity = (myopacity / 100);object.MozOpacity = (myopacity / 100);object.KhtmlOpacity = (myopacity / 100);
object.filter = “alpha(style=1, opacity=” + myopacity + “)”; }</script>
</head><body><form id=”form1″><div><table>
<tr><td><div style=”width:300px; height:30px; background-color:#FF0000;font-family:impact; font-size:18pt; filter:alpha(style=1, opacity=100); -moz-opacity:90″ id=”divUsers”>Fade This Text</div>
</td></tr><tr><td>
<a href=”javascript:opacity(‘divUsers’)”>Hide</a> </td></tr></table> </div></form></body></html>
