JQuery Opacity Change

Question

I have this code:

$('a[rel="imagesHandler"]').hover(
    function(){
        //ia latimea
        var liWidth = $(this).width();
        $(this).append('<div id="editBar"><a id="delPic" href="#"><img id ="piDe"src="./images/pic_del_icon.png" alt="" /></a></div>');

        $('div#editBar')
            .css({  'width':liWidth - 3,
                'height':'19px',
                'padding-left':'3px',
                'padding-top':'1px',
                'float':'left',
                'position':'relative',
                'top':'-22px',
                'z-index':200,
                'background-color':'black',
                'opacity':'0.5'
            })
            .hide()
            .fadeIn('slow');

        $('a#delPic').click(function(event){
            event.stopPropagation();
            alert('gigi');
            return false;
        });
    },
    function(){
        $('div#editBar').hide('slow');
        $('div#editBar').remove();
    }
);

So, I will add that this pops up on the mouse, inside this div there is a # delPic. I changed the opacity of div # editBar to 0.5, but it applies to # delPic as well. So, I want to change the opacity of a # delPic to 1. How can I do this? I tried several versions. That's why I anchored this identifier (trying to select it right away), but it still doesn't work.

Opacity will be applied to all elements inside, you cannot change this behavior. But you can do a little trick:

$('a[rel="imagesHandler"]').hover(
function(){
    var liWidth = $(this).width();

    $(this).append('<div id="editBar"><div class="transparent"></div><a id="delPic" href="#"><img id ="piDe"src="./images/pic_del_icon.png" alt="" /></a></div>');

    $('div#editBar .transparent').css({
        'position': 'absolute',
        'left':'0',
        'right':'0',
        'top':'0',
        'bottom':'0',
        'background-color':'black',
        'opacity':'0.5'
    });

    $('div#editBar').css({'width':liWidth - 3,
        'height':'19px',
        'padding-left':'3px',
        'padding-top':'1px',
        'float':'left',
        'position':'relative',
        'top':'-22px',
        'z-index':200
    }).hide().fadeIn('slow');

    $('a#delPic').click(function(event){
    event.stopPropagation();
    alert('gigi');
    return false;
    });
},

function(){
    $('div#editBar').hide('slow');
    $('div#editBar').remove();
}

);

Answer 3

This is because the tag is inside the div, when you apply an opacity change to an element, it also affects all elements inside it.
