.style works in FF but not IE

This piece of code works in FF

firstSelectedDiv.style.opacity = '0.5';


How come it wont work in IE7?

I have tried looking it up but i cant find any answers or help, probably because im not typing it in correctly.

Thanks for any help.

I was able to find this also. It doesnt work for IE, it just sends an error


secondSelectedDiv.style.filter = 'alpha(opacity='50')';


Still cant seem to find out whats wrong

Firefox uses MozOpacity , see http://www.javascriptkit.com/dhtmltutors/opacityns6.shtml

May be an issue with escaping quotes, try
secondSelectedDiv.style.filter ="alpha(opacity='50')";

That worked, it took me while to figure out the alternative JS for FF but i got it, thanks for letting me know anyways.

Want to quickly point out that firefox uses the regular "opacity: 0.5" as well. Use MozOpacity only when you don't want transparency in safari and opera.
