Nivo Slide using DIVs instead of IMG
提问by curly_brackets
I've found Nivo Slider to be the best solution for my site. However, I want it to make DIVs to slides, and not IMGs like it does by default. I've tried to change all IMG to DIV in the JS-file, but ofcourse without any luck...
我发现 Nivo Slider 是我网站的最佳解决方案。但是，我希望它可以将 DIV 制作成幻灯片，而不是像默认情况下那样制作 IMG。我试图将 JS 文件中的所有 IMG 更改为 DIV，但当然没有任何运气......
Can anyone help me??
谁能帮我？？

Edit: The slice effect can't be applied to any element other than an image, since the script generates slices (divs) with the image as background-image. The background-image is positioned according to the position of the slice and then the slice (div) is moved top down, bottom up or whatever. Again, can't be done with any element other than img, since you can't set the contet of a div to a background of another div. (Well I guess it could be done with css 3 and html 5 - but waaait for it :-))
编辑：切片效果不能应用于图像以外的任何元素，因为脚本生成切片 (div)，并将图像作为背景图像。背景图像根据切片的位置定位，然后切片（div）从上到下，从下到上或其他任何移动。同样，不能使用除 img 以外的任何元素，因为您无法将 div 的内容设置为另一个 div 的背景。（好吧，我想它可以用 css 3 和 html 5 来完成 - 但它是 waaait :-)）
There are a few things you can do. Dive into javascript and change nivo according to your wishes or write your own plugin. See a tutorial here. Since this could be quite a lot of work and you probably don't want to reinvent the wheel, I suggest you use a plugin which has a better support for customization. To get a grasp of a plugins level of possible customization, you should always take a look at the defaults. Generally - the more 'defaults' (== available options) - the better. There are thousands of blogposts about jquery content slider plugins, (yes, you search a content slider, not an image slider ;-)). So try your luck on google or check out the following:
您可以做一些事情。深入研究 javascript 并根据您的意愿更改 nivo 或编写您自己的插件。请参阅此处的教程。由于这可能需要大量工作，而且您可能不想重新发明轮子，因此我建议您使用对自定义有更好支持的插件。要掌握可能自定义的插件级别，您应该始终查看默认值。通常 - '默认值'（== 可用选项）越多 - 越好。有成千上万篇关于 jquery 内容滑块插件的博文（是的，您搜索的是内容滑块，而不是图像滑块；-)）。所以在谷歌上试试你的运气或查看以下内容：
- bxSlideris quite nice (and looks like the one you originally wanted.
- The coda slider.
- One of those the 30 best... blogposts.
Hope this helps.

Take a look at Rhinoslider.
看看Rhinoslider。
It's able to do transitions similar to nivoslider with html elements.
它能够使用 html 元素进行类似于 nivoslider 的转换。
