通过 data-* 属性触发模态
添加data-toggle="modal"和data-target="#modalID"到任何元素。
笔记：为了<a>元素，省略data-target，并使用href="#modalID"反而：
示例
<!-- Buttons -->
<button type="button" data-toggle="modal" data-target="#myModal">Open Modal</button>
<!-- Links -->
<a data-toggle="modal" href="#myModal">Open Modal</a>
<!-- Other elements -->
<p data-toggle="modal" data-target="#myModal">Open Modal</p>
