QUESTION
I'm trying to make a jiggle-type animation for a cta button that runs after a specified delay to draw the viewers attention onto it.
But it doesn't quite work as expected because if you see the spring object
ANSWER
Answered 2021-May-05 at 23:38It feels like a delay but actually, it is just the first animation keyframe finishing up before the next one starts.
Try adding duration to your config config: { tension: 200, friction: 5, duration: 200 },
or
Try adding clamp to your config config: { tension: 200, friction: 5, clamp: true },
React-Spring uses physics animations and I got tripped up on this too when I was starting. The interpolations are happening on a small scale so that you don't notice that they are still running.
QUESTION
I am want to read the data from a csv
file. but the file have different field inside at the end of the file. I do also want to extract those line, when meet the ErrFieldCount
. How can i do that.
ANSWER
Answered 2021-Apr-28 at 09:10When csv.ErrFieldCount
is returned, you still get the (parsed) line in your record
variable, so just print that. This is documented at Reader.Read()
:
f the record has an unexpected number of fields, Read returns the record along with the error ErrFieldCount.
And don't use log.Fatal()
to print a message as that terminates your app.
QUESTION
There is a scroll event happening with unknown source when using iOS safari.
To reproduce the issue You can use this link to explore a minimal example of the issue.
Using an iphone, try to scroll until you get rid of safari bottom nav bar, then scroll in the non scrolling red area at the very bottom edge of the screen.
- What's causing that behaviour (event name) ?
- Can scrolling be prevented using this method with Javascript without extra css ?
Update 1 : While there is no known method to solve this as it seems, force showing the bottom all the time did work for my specific use case.
...ANSWER
Answered 2021-Apr-19 at 12:38Safari on iOS has a so-called overscoll/bounce effect. You can eliminate the effect by using position:fixed
on the body. Disadvantage is that the bottom navbar appears again, but at least the following code prevents scrolling of the red area.
In your css, set the width of the body:
QUESTION
following are my files for html, .ts and json . As json data was very extensive therefore i have just added a few states and their cities. my 1st dropdown is showing all states. Now I want to match my 1st dropdown's selected value of state with a key "state" in "cities" object in my json file so i can populate 2nd dropdown with cities relevant to that state. and I want to do this in function "getCitiesForSelectedState". please help me find solution for this.
//.ts file
...ANSWER
Answered 2021-Apr-27 at 16:44You can do it with the $event
parameter.
Make sure to compare your values safely.
If your value is not in the right type or has spaces or unwanted chars, this c.state == val
might not work.
You can use the trim
function to compare your value safely:
c.state.trim() == val.trim()

QUESTION
simple question. I dont understand one thing.
...ANSWER
Answered 2021-Apr-17 at 21:16os.Create
returns *os.File
[1], as you said.
io.Writer
is an interface. That means, any types that implement the interface,
can act as the interface. In this case, the type only need to implement a Write
function [2].
Since os.File
does implement a Write
function [3], it can be used anywhere
a io.Writer
is required.
QUESTION
I am sorry if this is really basic question I am just starting out with programming I have looked up online couldn't find anything to solve this issue. while running my program I encountered this message "what(): std::bad_alloc" this is the first time ever for me, the program will run 2 out 5 times and for the rest I get this error in console. I don't know if something is wrong with my system or code. I really appreciate any feedback.
here is the code I am trying to write function for sorting and searching.
...ANSWER
Answered 2021-Mar-24 at 06:29Your program is throwing an std::bad_alloc
exception at some point and, since your are not handling this exception, it halts. This is due to some flaw on memory management.
Check your bubble-sort algorithm. Specifically, the for
loop:

QUESTION
I am trying to have a list of table fields which can be added and removed at any time.
IssueAs soon as I click delete any element in the middle(except the last one), it deletes all items underneath it
Code is here
I am not sure what is it that's doing wrong, it removes all the elements, even if I try to delete a specific one.
Adding code here also ...ANSWER
Answered 2021-Mar-02 at 12:24the issue is everytime you create a new element a new remove
function is created with reference to that current state in time. When you create an element, you create a jsx with a remove
pointing to that array
reference specific in time.
You could fix that changing your remove
function to something like:
QUESTION
I'm pretty much new to Typescript world and am converting one of the first React applications.
Here I'm trying to set custom messages on input validation by using event.target.setCustomValidity
but I'm getting the 'Illegal invocation' error when the setCustomValidity function gets triggered.
Here there is the sandbox; To trigger the error it's just required to update the first input.
Debugging the error, I'd think the issue stands on the declared type of event.target
set as HTMLInputElement
, or on the declared type of event
set as a React.SyntheticEvent
; Perhaps I'm using the wrong types for the event which doesn't always have a setCustomValidity function?
To premise the code used on the sandbox works perfectly fine without Typescript
Any suggestion is highly appreciated, thank you in advance for your help!
Components code
App.tsx:
...ANSWER
Answered 2021-Jan-04 at 17:55As @Heretic Monkey pointed out, you should use event.target.setCustomValidity
rather than destructuring the method.
Then, to properly type the event you may want to start by changing the onChange
typing in Input.tsx
.

I am building a simple model on Minizinc 2.5.3 (latest version) and Gecode 6.3.0 to try and organize a weapons production operation. When running the code, the following error appears:
...ANSWER
Answered 2020-Dec-07 at 23:49The cause of your problem is that floating point variables in Gecode are limited to 32 bits. This means that some problems that can be created in MiniZinc (which support 64 bit floating point numbers) cannot be solved by Gecode.
