QUESTION
I am trying to create a menu for practice, that contains different categories of meals. (i.e breakfast, lunch, snacks, etc.) I am making this menu to where there are 8 rows that when one of them is clicked, it shows a previously hidden description about that particular item. I am having trouble implementing the JS behind showing the menu description. I am not sure if all of the rows need to have unique class names, but I am not sure exactly how to select one row when clicked and then produce the output for only that particular row. Here is my current code at the moment (Note: The description has not been created yet) Also, I am new to web development, so anything that would point me in the right direction, even if it's not a full answer will be helpful :)
HTML
...ANSWER
Answered 2022-Mar-30 at 01:51Elements do not need to have distinct class names, but you can use additional class names as needed and be as specific as needed when referencing elements with the specified class(es).
I recommend using the id attribute for distinct element selection to reference them in javascript using getElementById. Then use addEventListener to place a click eventListener on each of the
getElementsByClassName or querySelectorAll, then apply event listeners in a forEach loop as follows.
Note: although options has a forEach method like an Array, it is actually an HTMLCollection

I am trying to create a profile button using TouchableOpacity. I have setup the mapStateToProps and the mapDispatchToProps properly. However when I set the onPress to this.props.openMenu, it states that undefined is not an object (evaluating 'this.props')
Any idea on what I can do to fix this problem? I am learning React Native so there may be some things that I am missing.
Here is my current code:

I'm using firebase Firestore to store my chat messages in it ! everything works fine but the only problem I'm facing is that messages are not showing directly after sending them ! I used useEffect and useLayoutEffect but still nothing works ! maybe I'm not using the right dependencies
I tried using messages as dependency so after the messages get a new message it re-renders ! but still not working ?
...ANSWER
Answered 2022-Mar-18 at 22:25getDocs fetches data once and is done. You could just run the fetchMessages function again after sending a message. Note that this isn't a very proactive solution and only fetches messages once when the component mounts and only when this client sends a message.

QUESTION
Hello all and thanks in advance.
Just to begin with, I am aware that weather data is not a suitable use case for RTK Query as it is always changing, I am using RTK Query in this case just for practicing purposes.
I want to refetch weather data upon a button click but the component is not being updated, however I can see that the requestId is indeed changing when clicking the refresh button and that data is being retrieved, by checking the console.
I am doing the refetch as in the example that can be found in the official docs:
I am also wondering if it would be more suitable to use useLazyQuery and its trigger function instead...
https://redux-toolkit.js.org/rtk-query/api/created-api/hooks#uselazyquery
...but if so, what should I take into account in order to decide if I use useQuery or useLazyQuery?
...ANSWER
Answered 2022-Mar-15 at 11:20I'm not allowed to leave a comment yet, so I'll try to answer you question regarding useLazyQuery vs useQuery here:
useQuery - got triggered on render. Retriggered on params change. Returns data from cache if the cache has some valid data. refetch allows to ignore cache, and forces to make a real API call. refetch has no query params, so you'll need to pass them to initial hook call.
useLazyQuery - got triggered firstly on trigger call, expecting the query params to be passed to trigger, and by default will do a real API call. To get the cached data first (if exists) - you'll need to pass the preferCacheValue param to the trigger function as the second param.
So the "rule of thumb" will be to use
useQuery by default to fetch data on the component mount, use refetch when you want to make a real API call ignoring the cache.
useLazyQuery - for cases like yours, when you want to make a call only later (ignoring the render stage) calling the "trigger" on some event (like a button click), and remember about the preferCacheValue option for a case when you have a chance to have the response already cached - this will allow making response feels instantaneous.
In our case - useLazyQuery is MUCH relevant, due to you can avoid all that setCurrentPosition => dispatch => useSelector stuff, and pull all that logic just in click handler, where you'll be able to fetch Geolocation.getCurrentPosition() and pass coordinates to trigger function, that where relevant to the click time, not to the time when the component was rendered.

QUESTION
I am in the process of implementing drawer navigation with nested tab navigation within my app.
At present I have two issues that I cannot work out so far and am looking for pointers. I am using React Navigation v6.
Upon clicking any of my tab navigator links I notice that my screen title is always set to "Home". Can this be updated to the current selected tab?
The last clicked tab appears to keep its state when using the drawer links, the journey would look like
- Start on home page (Renders home screen fine)
- click userprofile tab (Renders user profile page fine)
- then click "Book New Class" from within the Drawer, (Renders New Class page fine)
- then click "Home" from within the Drawer (This renders the user profile screen)
