我这里有点问题。我在网上找到了这个脚本,并根据我的需要对其进行了一些修改。此脚本显示鼠标悬停后的图像预览。
最初,只有一种方法可以做到这一点。但是我的网站上有 2 个不同的部分,我想在其中显示具有不同属性(高度、宽度)的图像。我能够做到这一点,问题是在第二部分,src(文件名)是我要显示的实际图片的缩略图,所以当它下降时,它只会炸毁一张非常小的图片,看起来很坏。但希望这会让事情变得更容易:所有缩略图都被命名为 whaterver_small.jpg 和原件,whaterver_small.jpg 现在,如果我可以删除 _small 或 _small.jpg 并从该文件的末尾替换为 .jpg,那将显示对我来说是原始图片,这将是很棒的。这是在 html 上调用函数的方式:
原尺寸,无需更改:
<a href=http://www.whatever.net/1.html');">
<img alt="Copper" border="1" height="64" src="http://www.whatever.net/whatever_small.jpg" width="85" onmouseover="showImage1(this.src,this,'Whatever')" /></a>
显示image2,我遇到问题的那个。
<a href=http://www.whatever.net/1.html');">
<img alt="Copper" border="1" height="64" src="http://www.whatever.net/whatever_small.jpg" width="85" onmouseover="showImage2(this.src,this,'Whatever')" /></a>
这是脚本
var floatWidth = 150; // set the width of the floating image
var floatHeight = 100; // set its height
var floatWidth2 = 320; // set the width of the floating image
var floatHeight2 = 240; // set its height

更新:
好的,所以我更新了此页面中的脚本,现在它可以正常工作了。我遇到了另一个问题,当鼠标悬停的图片接近页面末尾时,预览被截断。我希望能够向上移动预览,所以没有滚动条。这是一个功能性的活生生的例子:http ://www.soccer.com/Navigation.process?Ne=178& N=4294960224+346 图片永远不会被截断。
