QUESTION
I am building an app following the Rest Countries API challenge from frontendmentor (https://www.frontendmentor.io/challenges/rest-countries-api-with-color-theme-switcher-5cacc469fec04111f7b848ca). I have run into a problem. When clicking on the router link in countryDetail.js, the url changes but the component doesn't get re-rendered unless the page is refreshed.
CountryDetails.js
...ANSWER
Answered 2021-Jun-15 at 17:07The issue seems to be that you are already on the "/country/:name"
path and are clicking to visit another country. The router correctly updates the URL in the address bar, but because CountryDetail
is already mounted it neglects to recompute the item
and allCountries
state. This is because the useEffect
hook only runs once when the component mounts.
The name
param (match.params.name
) is actually a dependency for the GET requests, it should be added to the useEffect
hook's dependency array.

I'm trying for a long time to get my labels on the left side on my input fields. I'm banging my head against the wall. I use a font-awesome icon in the label.
I tried a lot of searches on Google and Stack Overflow and tried stuff like inline-block which I see should work but it didn't work for me. My code so far. I guess it's an easy fix for all the great people that are here.
...ANSWER
Answered 2021-Apr-13 at 19:11The easiest method, in my opinion, is to turn .wrapperSnippet
into a CSS Grid layout.
Grid is supported by all modern browsers but IE supports an older version of the spec.
We can define the grid with two columns: one of width auto
, and the other with 1fr
. auto
means that it will take up as much space as needed to fit the element, then the 1fr
will fill the remaining space.

QUESTION
The program logic for the section where I run into trouble is that the function, named handleOperation, for handling state change(this.setState) will be invoked and supplied with two arguments once the corresponding buttons are clicked and the event is triggered, which calls handleOperation function and passed two arguments(obtained from event.currentTarget) to it. However, the console.log prints "submit" for the prop("type") that I intend to grab(It should have returned the value for "type"-either "sesnLength" or "brkLength" in this case)
This is the link to the project I am currently working on.
The following is the code snippet for my class component(parent component) where I supply child component(TimerLengthControl) with "type" property.
...ANSWER
Answered 2021-Jun-14 at 04:39The only valid values for the type
attribute for HTML button
elements is "submit"
, "button"
, and "reset"
. This is why you are seeing the console log "submit" always.
I suggest converting the handleBreakLength
and handleSessionLength
click handlers to curried functions to close over a type
key for the state updates.

I am trying to build a responsive navbar, unforunately the checkbox isn't working. I was following along a youtube video for the navbar. This is my HTML code:
...ANSWER
Answered 2021-Jun-13 at 16:06You can start taking the checkbox outside nav and insert it right before nav so your CSS selectors are efficient.
update then #click:checked~ ul
to #click:checked~nav ul
to follow the html structure .
