I'm using google-map-react
to display places on google map with auto-suggestion feature, following example here: https://www.freakyjolly.com/google-maps-in-react-example-application. I'm using Typescript so my code is different from the blog.
I'm having a problem right now : console.log(autoComplete);
in function onPlaceChanged
print undefined
. Any idea why this is happening, and how can I fix it?

This is because you are closing over the initial undefined autoComplete
state in the callback.

I am creating a tag cloud word cloud using the React library from AnyChart. How do I change the color theme of it? The answer found here doesn't seem to work:

Answered 2021-Nov-22 at 03:05It is available if you are using the instance
attribute. THe idea is to create the chart with the usual library API, and then apply this instance to the component. In this case, all library features are available via API.
So, you can use this call

QUESTION
I would like to know what is the proper way to create several drop-down-menus (), with a loop, where i can then access their selected value through a button.
I tried to recreate what I currently have in my code so i hope this is enough.
(The reason i put
elements in an array is because i use different arrays to generate a table with rows in my original code.)
Currently getValue()
, that is trying to get the value from the 1st drop-down-menu, prints ''
which is the initial value, even when i change the value from the menu. I think the problem is that putting them in array is causing them not to update their own value when changed. Is there a way to get around this problem?
This code is also causing this.state.value
to only be set on the last drop-down-menu that was changed.
I understand why this is happening but i don't know how to get around it.
ANSWER
Answered 2020-Aug-01 at 16:15Here's a working codesandbox.
Note that you can return markup directly from a function without the need to store in state first, this is what I did with populateRows
.
Value of each dropdown should be mapped to a specific index of an array in the state (or some other similar data structure to store multiple values). This maps a given dropdown's value to a specific item in an array: value={this.state.values[index]}
HTML elements in a map
function in React must have unique key
attribute so that React can correctly see what has changed between renders (there's actually more to that, but it's another topic). In my case I chose the index just for the example, but you can google about this and see how to correctly choose a unique key (rather use some known ID).
Initially the array in the state is empty so you get []
for the stringified value at the bottom. As you change values in dropdown the array will be filled/modified.
I hope this helps and of course, ask if there's something unclear.
QUESTION
I am trying to set the window dimensions during window resize event using a debounce method. It seems that the dimensions are set only the first time that the code runs. When i am trying to resize the window the dimensions does not change. I create a sandbox example https://codesandbox.io/s/react-example-ciq1l
...ANSWER
Answered 2020-Jun-18 at 11:40You don't need to set timer
inside return
part of debounce
.
Another thing, any time you get inside debounce
function you are assigned new var timer
, so the check of if (timer)
right after never gonna apply
QUESTION
I am trying to build an analog clock with the second hand rotating every second, min hand rotating 6deg every minute and hour hand rotating 6deg every 12 minutes.
Here's the codesandbox: https://codesandbox.io/s/react-example-d7mes?file=/Clock.js
Whenever the min hand's angle is either of these [72, 144, 216, 288, 360]
(12 minute degrees), I rotate the hour hand by 6 degrees once.
This is what I'm doing:
...ANSWER
Answered 2020-Jun-11 at 20:09There's a fundamental design problem here which is that setInterval
is the wrong tool for keeping time. setInterval
only guarantees that the callback won't run for at least 1000 milliseconds, not that it will run exactly in 1000 milliseconds, so you're going to wind up with drift and skipped times.
I recommend using requestAnimationFrame
and the Date
library to determine when ticks have occurred.
With this set up, you can scale the hour hand proportional to the number of minutes left in the hour with:

I am trying to figure out if it's possible to capture input/checkbox onchange events and update the state from the same function? The reason behind this is that I am still learning React and would like to learn how to save the state properly.
I've tried to save the state the following way, but I am probably making some mistakes:

QUESTION
I am trying to load images at the same time in React.js.
I tried a lot but still not able to figure out, how to do it.
- This is the first thing, I tried to load images normally.
ANSWER
Answered 2020-Mar-02 at 15:47You can use your second approach, and hide an image until the other has loaded, here's a working sandbox link (based on your link): https://codesandbox.io/s/react-example-3iblh
e.g. for the first image, you handle visibility based on state:
visiblity: this.state.imageTwoLoaded ? "visible" : "hidden"
QUESTION
Here is a codesandbox for the problem.
The example has three parts:
- React functional component.
- Vanilla JS grid library.
- useEffect to combine them both.
One useEffect instantiates the grid, while another listens for state changes to update the grid.
Everything works fine until a row is clicked in the grid library.
I get this error.
...ANSWER
Answered 2020-Feb-25 at 10:42I managed to solve it with useRef
for the function variable, and by moving the function definition inside the useEffect
