jQuery CSS Opacity

Question

What's wrong? I want to change the opacity if #nav .drop is display:block;

jQuery(document).ready(function(){
    if (jQuery('#nav .drop').css('display') === 'block') {
        jQuery('#main').css('opacity') = '0.6';
    }
});

Try this jQuery('#main').css({'opacity':0.6}) ; – Floatation

Is this for a drop down menu? Presumably if the drop is not display: block it is hidden, so why not just set it permanently to 60% opacity? Or am I missing something? It would be nice to see a working example of this. – Kamp

Answer 1

jQuery('#main').css('opacity') = '0.6';

should be

jQuery('#main').css('opacity', '0.6');

Update:

http://jsfiddle.net/GegMk/ if you type in the text box. Click away, the opacity changes.

yep, found that just in time, but it still dont work. Any other idea? – Chaps

Opacity value should not be a string, so: 'jQuery('#main').css('opacity', 0.6);' – Unfathomable

Answer 2

Try with this :

jQuery('#main').css({ opacity: 0.6 });

Answer 3

Try this:

jQuery('#main').css('opacity', '0.6');

or

jQuery('#main').css({'filter':'alpha(opacity=60)', 'zoom':'1', 'opacity':'0.6'});

if you want to support IE7, IE8 and so on.

Answer 4

try using .animate instead of .css or even just on the opacity one and leave .css on the display?? may b

jQuery(document).ready(function(){
if (jQuery('#nav .drop').animate('display') === 'block') {
    jQuery('#main').animate('opacity') = '0.6';
