fiora | An interesting open source chat application Developed with nodejs, mongoDB, socketio and react | Chat library

what I'm trying to do: when something is typed in the search bar, the user names that are not searched for must fade out and disappear (which works fine), and I'm trying to reverse this animation when the letters are deleted in the search bar or the search bar is cleared.

App.js

To be clear with document.write(), I know this is outdated and do not want to reload and close the website. So I came up with document.getElementById().innerHTML for an alternative.

However, the problem is, document.getElementById().innerHTML does not bring me the result I wrote for but document.write() does.

So, how can I develop my document.getElementById().innerHTML code as the result of using document.write()?

I've been looking for the differences between .write and .innerHTML though, could you help me to understand the remarkable differences between two of them with the example I bring in?

Here is the code.

(Complete noob here, appologies if I'm unclear!) I have been using Riot Games' API to get information of a players stats on specific characters in a game. I used Json2CSharp in order to create the following data object.

I have a div.header with a div. search where my input tag exists with my call function. I also have div.content with all the elements to search for. They are located in different div tags, but the call function for my JavaScript is only in the input tag. Problem is when i type in the input tag my console tells me this:

(21) Champions.htm:564 Uncaught TypeError: li.getElementsByClassName is not a function at searchfunction (Champions.htm:564) at HTMLInputElement.onkeyup (Champions.htm:39)

The solution I'm looking for is how I make my input tag remove search elements when I type in a specific champion name. Example:

Typing in A into the input tag should remove all the elements with h3 tags that don't match the search criteria.

Note: My h3 tags are filled in with specific names. And these names are what the searchfunction() should be looking for and removing from the page if they don't match the search criteria.

I'm not much of a JavaScript fan, so most of my tries have been in vain.

Im looking to use some reflection to access all the members in a class and get their values. This is the class's. I always initialize the "Championsids" class. (I know there is a lot of code but its quite straight forward).

Today i'm struggling once again with python and data-analytics.

I got a dataframe wich looks like this:

I have two files:

In the first one (champions.csv) I have the number and the name of some LoL champions

I have a string:

I am learning python data analysis by reading other people's codes step by step. I have a DataFrame named df like this:
