kandi X-RAY | GoBack Summary
GoBack is a simple file backup tool, similar to Microsoft's SyncToy. By giving GoBack a source and destination directory, it checks if each file in the source directory is in the destination directory. If it [the current file] is in the destination directory then nothing happens, if not then it is copied across. This means the program only copies across the differences, creating fast incremental backups where no files are ever deleted or overwritten in the destination directory. Prebuilt program files are available on GitHub.

QUESTION
I have a screen that displays a Flatlist with some data in it, but when I go back to the previous screen and come back back to this acreen with the Flatlist, the data is not more there. I use React Navigation to move between screens and also to move data.
This is the code I use to go back:
...ANSWER
Answered 2021-Jun-10 at 22:53When you are on the first page, only that page is mounted. Then you go to page2 with the Flatlist. Now both page1 and page2 are mounted.
When you use navigation.goBack()
, page2 is unmounted. This means this.state
on page2 is deleted.
So now when you go to page2 for the second time, it is re-mounted (so a new/empty state is used)
If you want to preserve the state between mount/unmount/re-mount, you will either need a state management tool, or pass all data via the navigator.

I'm building a RN app and I just recently learned REDUX and applied it into my app. I have a shopping cart feature in my mobile app. On one screen the user can add items to the cart. Then when they are done they can click the cart icon to view the full cart (new screen).
Shown below is the code for my cart screen.

QUESTION
I've found a very useful Jquery example to filter divs based on changing select options.
Here is the fiddle: https://jsfiddle.net/vgdwyqxb/
My problem is: I use this code for filtering projects and every single project has a URL that goes to another page. When a user clicks on a project, he/she goes to project detail page. On those pages, there is a "Go Back" button. When they go back, all filtering selections are lost. I want to hold the filter selections.
I added a goBack() method in other page to go back to filter page. When I click on goback, filter page remembers which option was selected but all divs appear (not filtering divs). As far as i know "changing option" must be done in order to filter divs, so when i go back to filter page, even my last selected option is selected, it doesn't filter anymore.
My question is: What should i do to make filter page remember when users go back from project detail page?
Thanks in advance.
...ANSWER
Answered 2021-Jun-09 at 14:15To achieve your goal you can use localStorage()
to save a JSON-encoded string which contains the last selections made from the three filter select
elements.
When the page is loaded you can then retrieve that JSON, apply the selected values back to the select
and filter the content once more.
Here's what the code to do this could look like:

QUESTION
I have been making an Atari Breakout inspired game based off of a tutorial. I was wondering how to make a "GAME OVER" screen that will show up once the player dies. The code that I have has a variable that I created called "DrawDeath()". I have it coded so that text appears when you die but for some reason it never shows up.
...ANSWER
Answered 2021-Jun-04 at 21:19You have some errors in your code so I correct what the console showed. I have also changed the code to use requestAnimationFrame
. Once a gameOver status has been triggered the requestAnimationFrame
will stop running and setInterval
will run the drawDeath
function. You also have an error in your game over text as you were missing the x and y coordinates.
Additionally I added the downPressed
variable that was missing so you could restart the game.

QUESTION
The image in the header constantly flickers when I type. May I ask how do I stop this flickering at the top right hand corner or accessoryRight? I am using this TopNavigation component from UI Kitten UI library. I don't think this is normal, it shouldn't happen at all. I must be doing something wrongly.
https://youtu.be/fQppQn-RzeE (How do I embed this? Editor, thank you in advance!)
The flickering happens in the title and the right side of the Navigation Header.
I made a separate component for the TopNavigation and then call it in respective screens.
Things I have tried:
- Since the outcome of the Header relies on
navigation props
, I tried usinguseState
anduseEffect
(with navProps as the dependency) to save the prop instead of reading directly fromprops
, but to no avail - Directly adding the jsx into the TopNavigation's
accessoryLeft/Right
andtitle
options
Any input is welcome, appreciate it!

Answered 2021-May-29 at 16:50Perhaps requiring the images just one time and not on every render may help. Try adding this at the top of the file (not inside a component function)
QUESTION
The WebView Code
...ANSWER
Answered 2021-May-30 at 13:47The problem is that the Webview
(ModalView
) assigns its own parent. This is a feature of the ModalView
. By returning a Webview
instance in your build()
method, you are attempting to set the App
as the parent of the Webview
. That causes the error you are seeing. You can solve this by returning something other than a Webview

QUESTION
this is my front end code, I think the problem is here. So, when the form is submitted everything that is supposed to work works but the email shows up empty. Also I was getting an error in the console here it is...
Can't perform a React state update on an unmounted component. This is a no-op, but it indicates a memory leak in your application. To fix, cancel all subscriptions and asynchronous tasks in a useEffect cleanup function.
So, i added that useEffect clean up function although im not sure if i did it right the error is gone. Are these two things related? Somehow the state is not being updated in time. If i hard code the message the email sends out fine. Thank you. Also any additional advice would be cool.
...ANSWER
Answered 2021-May-30 at 00:19You need three main changes:
- Set name attribute in input/textarea tags;
- In onChange handler, get name attribute with
e.target.getAttribute("name")
; - In onSubmit handler, remove setData, because is unecessary;
