面包屑导航的原理与作用

面包屑导航是一种网站或应用程序的导航方式，它通过在页面上显示当前位置和历史路径，帮助用户快速理解网站结构和内容，并方便用户回到之前访问的页面。面包屑导航通常出现在页面的顶部或侧边，在用户浏览网站时一直存在。它的原理是在用户进入每个页面时，记录下之前访问的路径和页面层级关系，然后将这些信息用面包屑导航的形式展示给用户。面包屑导航的作用主要有以下几点： 1. 帮助用户了解网站结构：通过显示当前页面的位置和路径，面包屑导航可以告诉用户当前页面所处的层级和位置，让用户更好地理解网站的结构和内容，有助于用户快速找到自己需要的信息。 2. 提高用户导航效率：面包屑导航可以方便用户回到之前访问的页面，节省用户找回信息的时间。 3. 提升页面的可用性：面包屑导航可以使页面更易于使用和理解，提供了一种方便、清晰、直观的导航方式，可以提高用户的满意度，降低网站的跳出率。总之，面包屑导航作为一种重要的导航方式，是设计者在构建网站和应用程序时必须考虑的因素之一。

面包屑导航(BreadcrumbNavigation)

这个概念来自童话故事”汉赛尔和格莱特”，当汉赛尔和格莱特穿过森林时，不小心迷路了，可是他们发现在沿途走过的当地都撒下了面包屑，让这些面包屑来协助他们找到回家的路。所以，面包屑导航的效果是通知拜访者他们现在在网站中的方位以及怎么回来。
