QUESTION
I'm doing a React coding challenge that requires a value to be updated onKeyUp. I initially set it to update onChange but the tests require onKeyUp so I tried to change it to that, but my fields are no longer updating and I can't type anything into the textarea.
...ANSWER
Answered 2018-Jul-12 at 01:40Since the event happens before the actual value of the textbox is changed, the result of event.target.value
is an empty string. Setting the state with the empty string, clears the textbox.
You need to get the pressed key value from the event, and add it to the existing state.value
.
Note: I've removed marked
from the demo

I'm struggling quite a bit with React-Redux. I watched Dan Abramovs intro to redux 3 times, followed along with the coding 1 of those times, read the Redux documentation twice, and went through the React and Redux sections of freeCodeCamp 3 times each but I can't seem to wrap my head around it. I get the very basics, but when it starts to get more complicated I get lost. I decided to try and build out the markdown previewer challenge to see if I could learn as I go, but I can't get the preview field to update as I update the editor field. This is what I have so far, I could get it to display basic HTML like "This is the header" a text box that says "This is the editor" and basic stuff like that, but now the next step I'm working on is getting the editor field to dynamically update the preview field. As soon as I started trying to do that, everything went blank and the console stopped giving me any feedback.

Answered 2018-Jul-08 at 21:57You're calling the reducer directly from your onChange property. Instead you should register the reducer in the store, and dispatch an action on the store, that in turn will use the reducer to update the state in the store.
You probably do not want to pass a raw event to dispatch, but something like this could work;
