Fading image inside a div

Question

I am trying to get it so when the mouse moves over the div it fades the image inside

function clickimage($imageid){              
$("#image_"+imageid).hover(function(){
$(this).fadeTo("slow", 1.0);
},function(){           
$(this).fadeTo("slow", 0.6);
});
}

<div id='images_$imageid'>
<a href='?tg=photos&photo=$imageid' onmouseover=\"javascript:clickimage('$imageid')\">
<img src='users/$ptgid/images/$iimg' width='100' height='100'/>
</a>
</div>

Answer 1

You would want to set the binding when the document loads, not every time the mouse hovers over the image. Also, I would create a class so that you can initialize the hover on each item

$(document).ready(function() {
    $(".image-hover-class").hover(function(){
        $(this).find('img').fadeTo("slow", 1.0);
    },function(){           
        $(this).find('img').fadeTo("slow", 0.6);
    });
});

For the link, you would do something like this:

<a class="image-hover-class" href="?tg=photos&photo=$imageid" \>
    <img src='users/$ptgid/images/$iimg' width='100' height='100'/>
</a>

If you want to do the hover on the div , you could do this instead (but I recommend doing the hover on the <a> tag):

$(document).ready(function() {
    $(".image-hover-class").hover(function(){
        $(this).find('a img').fadeTo("slow", 1.0);
    },function(){           
        $(this).find('a img').fadeTo("slow", 0.6);
    });
});

For the div, you would do something like this:

<div class="image-hover-class">
    <a href="?tg=photos&photo=$imageid" \>
        <img src='users/$ptgid/images/$iimg' width='100' height='100'/>
    </a>
</div>

This can be done just using css. I wrote a tutorial here:

Just include your orignal image and a "faded" image.
