Scrollspy的使用
使用Scrollspy只需在对应的HTML元素里添加几个关键的属性:
- data-spy=”scroll”
添加到需要滚动的元素中,比如最常见的body元素,或者container。
- data-target=”selector”
添加到需要滚动的元素中,selector指示的是控制滚动的元素比如”.navbar”, “#myScrollspy”。
- <a href=”#section”>section</a>
在控制滚动的元素中用link链接到对应的位置。注意链接的id要跟对应位置元素的id相匹配。例如,<div id=”section1”>与<a href=”#seciton1”。
