如何在鼠标悬停在照片下方添加说明? (照片库)

[英]How to add description underneath photo on mouse over? (photo gallery)

我正在制作一个简单的照片库,当前当用户将鼠标悬停在缩略图上时,其下方显示了放大的照片。

我还希望当用户覆盖缩略图时,我希望一些文本显示在白色文本框中。 每个缩略图应有不同的描述。 我需要JavaScript代码帮助,因为我不熟悉j查询。

这是我的代码,不胜感激!

您应该使用数据属性,基本上这是它的工作方式:

<img src="http://lorempixel.com/100/100/nature/6" 
     data-full="http://lorempixel.com/300/300/nature/6"
     data-small="http://lorempixel.com/100/100/nature/6"
     onmouseover="this.src=this.getAttribute('data-full');"
     onmouseout="this.src=this.getAttribute('data-small')"
     />
