如何使用Bootstrap Typeahead创建动态自动完成搜索

在这篇文章中,我们将学习如何使用Bootstrap Typeahead实现动态自动完成搜索。Bootstrap Typeahead是一个插件,有助于在搜索栏中添加一个漂亮的自动完成选项。

在这种方法中,我们将采取静态数据进行自动完成,但我们也可以使用动态JSON数据,以显示搜索选项。Typeahead插件中使用的方法如下。

  • .typeahead(options)。用一个typeahead初始化一个输入。
  • .lookup。要从外部触发查找功能。
  • .getActive。要获得当前的活动项目,你将得到一个字符串或一个JSON对象,这取决于你如何初始化typeahead。它只对第一次匹配起作用。

例子: 下面的例子演示了使用Bootstrap Typehead的动态自动完成搜索。
