如何在 Bootstrap 中设置 ScrollSpy 的偏移量属性？

原文:https://www . geeksforgeeks . org/如何在引导中为 scrollspy 设置偏移量属性/

偏移量是一个 Bootstrap Scrollspy 属性，其中用户可以指定在计算滚动位置时从顶部偏移的像素。当用户觉得导航条或列表很早就改变了状态，或者在冲浪时不需要时，它就变得很有用。它始终是一个数字，默认值为 10。该值可以通过 Javascript 或者将数据偏移值放入 body 标记中来更改。

语法:

正常申报
html (body data-offset="")

Javascript 声明
```html
$(document).ready(function(){
$('body').scrollspy({target: " ", offset: });
});
```

示例 1: 该示例描述了使用了四个部分的引导导航栏，并且使用 Javascript 将 offset 属性设置为 60。
