Hi Everyone,
I am using Unitpngfix for IE6 PNG Transparency. Everything moves fine.
Now i need to implement a menu button in png to swap when mouse over. I used dreamweaver "Add Behaviors > Swap Image". It generates a java script code.
Swap Image Script:
function MM_preloadImages() {
var d=document; if(d.images){ if(!d.MM_p) d.MM_p=new Array();
var i,j=d.MM_p.length,a=MM_preloadImages.arguments; for(i=0; i<a.length; i++)
if (a[i].indexOf("#")!=0){ d.MM_p[j]=new Image; d.MM_p[j++].src=a[i];}}
}
function MM_swapImgRestore() {
var i,x,a=document.MM_sr; for(i=0;a&&i<a.length&&(x=a[i])&&x.oSrc;i++) x.src=x.oSrc;
}
function MM_findObj(n, d) { //v4.01
var p,i,x; if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) {
d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n];
for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document);
if(!x && d.getElementById) x=d.getElementById(n); return x;
}
function MM_swapImage()
{ //v3.0
var i,j=0,x,a=MM_swapImage.arguments;
document.MM_sr=new Array;
for(i=0;i<(a.length-2);i+=3)
if ((x=MM_findObj(a[i]))!=null)
{
document.MM_sr[j++]=x; if(!x.oSrc) x.oSrc=x.src; x.src=a[i+2];
}
}
Unitpng fix script:
var clear="clear.gif"; //path to clear.gif
document.write('<script type="text/javascript" id="ct" defer="defer" src="javascript:void(0)"><\/script>');var ct=document.getElementById("ct");ct.onreadystatechange=function(){pngfix()};pngfix=function(){var els=document.getElementsByTagName('*'),ip=/\.png/i,al="progid:DXImageTransform.Microsoft.AlphaImageLoader(src='",i=els.length,uels=new Array(),c=0;while(i-->0){if(els[i].className.match(/unitPng/)){uels[c]=els[i];c++;}}if(uels.length==0)pfx(els);else pfx(uels);function pfx(els){i=els.length;while(i-->0){var el=els[i],es=el.style,elc=el.currentStyle,elb=elc.backgroundImage;if(el.src&&el.src.match(ip)&&!es.filter){es.height=el.height;es.width=el.width;es.filter=al+el.src+"',sizingMethod='crop')";el.src=clear;}else{if(elb.match(ip)){var path=elb.split('"'),rep=(elc.backgroundRepeat=='no-repeat')?'crop':'scale',elkids=el.getElementsByTagName('*'),j=elkids.length;es.filter=al+path[1]+"',sizingMethod='"+rep+"')";es.height=el.clientHeight+'px';es.backgroundImage='none';if(j!=0){if(elc.position!="absolute")es.position='static';while(j-->0)if(!elkids[j].style.position)elkids[j].style.position="relative";}}}}}}

The swap image concept along with png transparency is working fine in all browsers.
But i am getting a bug in IE6 when i mouse over. Without mouse over on initial page load menu button with png transparency is working in ie6, when i take the mouse over the image the swapping png image comes but the transparency is gone.
I think the unitpngfix script is deactivated when mouse over.
Need some suggestions/help to activate the png transparency on mouse over.
looking for some reply,
