B开发者_开发百科ut only for anchor tags not for images, let say I have anchor background blue and I want it to change to red but with this effect, how can I do that? thank you
Use hover and animate. Note that this requires the jQuery color animations plugin.
<html>
<head>
<title>color change</title>
<script type="text/javascript" src="http://code.jquery.com/jquery.js"></script>
<script src="http://plugins.jquery.com/files/jquery.color.js.txt" type="text/javascript" charset="utf-8"></script>
<script type="text/javascript" charset="utf-8">
$(function() {
$('a').hover(function() {
$(this).animate({
color: "#f00"
}, "fast")
}, function() {
$(this).animate({
color: "#00f"
}, "fast")
});
});
</script>
<style>
a { color: #00f; }
</style>
</head>
<body>
<a href="#">This changes color on hover.</a>
</body>
</html>
In the example of changing color on an a element there is no reason to use the crossfade effect used in the link you provide.
Placing two images on top of eachother (via CSS: position and z-index). A black and white one, and a color one:
/* Assumes width and height are the same between all three elements */
.viewBox { position:relative; width:125px; height:125px; display:block; }
img.color { position:absolute; top:0; left:0; z-index:10; }
img.bandw { position:absolute; top:0; left:0; }
<a class="viewBox" href="http://google.com">
<img src="color.jpg" class="color" />
<img src="bandw.jpg" class="bandw" />
</a>
$(".viewBox").hover(
function() {
$("img.color").fadeIn();
},
function() {
$("img.color").fadeOut();
}
);

Alternatively, you can accomplish this without jQuery, using pure css too:
span.hov span { display:none; }
.rollover { display:block; background-image:url('bandw.jpg');
width:125px; height:125px; }
.rollover span.hov { display:none; background-image:url('color.jpg');
width:125px; height:125px; }
.rollover:hover span.hov { display:block; }
<a class="rollover">
<span class="hov">
<span>Invisible Link Text</span>
</span>
</a>
The HTML, CSS and jQuery is available on the web page for you.
Here, the creator has layed 2 images on top of each other then uses jQuery to change the opacity.
<div class="fadehover">
<img class="a" alt="" src="cbavota-bw.jpg" style="opacity: 1;"/>
<img class="b" alt="" src="cbavota.jpg"/>
</div>
$(document).ready(function(){
$(".a").hover(function() {
$(this).animate({"opacity": "0"}, "slow");
},
function() {
$(this).animate({"opacity": "1"}, "slow");
});
});
