最初,只有一种方法可以做到这一点。但我在我的网站上有两个不同的部分,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)是我想要显示的实际图片的缩略图,所以当它显示时,它只会炸掉一张非常小的图片,看起来很像很坏。但希望这会让事情变得更容易:所有的缩略图都被命名为whaterver_small.jpg和原文,whatever.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,那将显示这张照片对我来说很棒。这是在html上调用函数的方式:
原始尺寸,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 floatWidth2 = 320; // set the width of the floating image
var floatHeight2 = 240; // set its height

更新
好的,所以我更新了这个页面中的脚本,现在它运行得很好。 我遇到了另一个问题,当鼠标悬停的图片接近页面末尾时,预览会被截止。我希望能够向上移动预览,所以没有滚动条。 以下是功能实例的实例:http://www.soccer.com/Navigation.process?Ne=178&N=4294960224+346 图片永远不会截止。
答案 0 :(得分:0)
如果我理解你想要的内容,这将删除所有图片来源的所有_small
个匹配项:
$("img").each(function() {
$(this).attr("src", $(this).attr("src").replace("/_small(?=\.)/", ""));
});
答案 1 :(得分:0)
替换showImage2
功能
nIMG.setAttribute('src',isImg);
与
nIMG.setAttribute('src',isImg.replace(/_small\./, '.'));
