In-Page Filtered Search With Vanilla JavaScript

摘要

If you have a page that includes a lot of information, it’s a good idea to let users search for what they might be looking for. I’m not talking about searching a database or even searching JSON data — I’m talking about literally searching text on a single rendered web page. Users can already use the built-in browser search for this, but we can augment that by offering our own search functionality that filters down the page making matching results easier to find and read.
