jQuery滑块重定向图像

【中文标题】jQuery滑块重定向图像【英文标题】：jQuery slider redirect the image 【发布时间】：2012-04-19 12:37:42 【问题描述】：我使用jQuery Blinds Slideshow 作为图像滑块。当我点击它时，我想将第一个滑动图像重定向到http://google.com。我使用a这样的html标签：
<div class="slideshow">
<ul>
<li><a href="http://google.com"><img src="lemons/1.jpg" /></a></li>
<li><img src="lemons/2.jpg" /></li>
</ul>
</div>
<a href="#" onclick="$('.slideshow').blinds_change(0)">1</a>
<a href="#" onclick="$('.slideshow').blinds_change(1)">2</a>
但它不起作用。 我的问题是当我点击它时如何将第一个滑动图像重定向到 google.com？ 提前致谢。
【问题讨论】：
【参考方案1】：这是我修改原始 jquery-blinds 的快速而肮脏的东西。 将它放在一个新的 JS 文件中，并将其命名为 jquery.blinds-0.9-with-hyperlinks.js 或其他名称，并将其包含在当前 jquery-blinds 代码的位置。
它应该适用于您在上面发布的 HTML。它只是检查是否有任何图像包含在 '' 标记中，如果是，则使图像在点击时重定向到该链接。

【讨论】：
抱歉，这些不适用于此插件。当我为不在滑块中的图像尝试您的代码时，它确实有效，但是当我为滑块中的图像尝试此代码时，它不起作用:(您可以下载这个插件并尝试一下吗？ 你没有包含启用滑块的 js 函数 $(window).load(function () // 开始幻灯片 $('.slideshow').blinds(); )以上是关于jQuery滑块重定向图像的主要内容，如果未能解决你的问题，请参考以下文章
