How to open a text in the same html page by not creating a same page?

For example, when I open a topic, it would open in the same html page, not redirect to another address: http://web.archive.org/web/20090409012115/http://www.europeangoldfinch.net/home.htm#

I want to make it exactly like this (clicking on a topic). I downloaded the source files from web archive, but when I click on topic nothing opens up even though the topic text is in that html code.

This is exactly what I want to do: https://errorsea.com/how-to-change-text-onclick-event-javascript/#Syntax

EDIT: Thanks everyone for the help, I figured it out, I downloaded a website from web.archive.org, and it didn’t work well, but I managed to get it working with the javascript included with the website.

Code:

#This is the topics# #This is the topics# #This is the topics# #This is the topics# #This is the topics# #This is the topics#

                          <p>The EGF is a small passerine bird of the finch family. The EGF is approximately 11-13.5 cm (4-5 inches) long and weighs 16 to 22 grams. Sexes are alike, with a red face, black and snowy white heads, brown and white breast upperparts and black wings with yellow flares. They are simply beautiful!</p>
                          <p><u>Where do they live?</u></p>
                          <p>Typically EGF can be found throughout Europe, northern African and most of Asia. However, they have been spotted in and around Eastern portions of the United States and Northern Canada. In 2005, one was even spotted feeding in Michigan! I hope people will post more sightings here!</p>
                          <p><u>What do EGF typically eat?</u></p>
                          <p>Seeds and insects.</p>
                          <p><u>What is the life expectancy of the EGF?</u></p>
                          <p>5 to 8 years</p>
                          <p><u>Do EGF’s make good pets?</u></p>
                          <p>Yes! How do they ever! EGF’s are kept as cage-birds for their song, which is a very beautiful twittering.</p>

Years ago my wife and I have often talked of visiting Canada to do some bird watching ourselves but we never got around to it. Sadly, Irma passed away three years ago so we were never able to take our trip. I’ve heard Alberta can be quite nippy this time of year. I hope you stayed warm.</td>

Answer

I really don’t understand want you actually want but from the look of things, if I’m correct you want to use a #URL system in your page. So I assume you want the page viewport to be on blog0 div when the user clicks on

<td>
   <a href="#" onclick="showTopic('blog0');">
    FAQ: The Basics Behind the EGF
   </a>
</td>

if that is the case then you can this instead:

<td>
   <a href="#blog0">
    FAQ: The Basics Behind the EGF
   </a>
</td>
