如何使用png和jquery进行翻转? [英] How do I make a rollover using png and jquery?

问题描述

我对在网上找到的脚本进行了反向编码，并且效果很好，唯一的问题是，悬停图像会以完全可见的状态加载，直到发生悬停动作为止.这是脚本:

I reverse coded a script I found online and it works well, the only problem is that the hover image loads at complete visibility until the action of hover occurs. This is the script:

$(document).ready(function()
{
$("img.b").hover(
function() {
$(this).stop().animate({"opacity": "1"}, "slow");
},
function() {
$(this).stop().animate({"opacity": "0"}, "slow");
});

});
</script>

这是CSS文件:

<style>
div.fadehover {
    position: relative;
    }

img.b {
    position: absolute;
    left: 0;
    top: 0;

        z-index: 10;
    }

img.a {
    position: absolute;
    left: 0;
    top: 0;
    }
</style>

这是正文代码:

<div class="fadehover">
<a href=""><img src="portfolio_a.png" alt="" class="a" />
<img src="portfolio_b.png" alt="" class="b" /></a>

</div>

推荐答案

更改CSS以使其在加载时隐藏:

Alter your CSS to have it hide onload:

img.b {
    position: absolute;
    left: 0;
    top: 0;
    z-index: 10;
    opacity: 0;
    filter: alpha(opacity=0);
}

filter:alpha(opacity=0);行用于I.E.
