Answered 2021-May-27 at 11:21There is no path to the official file you are trying to add. You can get the file path by right clicking on the picture in the file and clicking copy relative path. then if you are using windows, you can use the file path after converting the '' \ '' s to '/' and putting them under assets in pubseps.yaml.

I'm working on a project which has to create a pdf. In some places there should be spaces between lines. But I can't find a way to do that. I tried adding an empty Text widget between lines to get with spaces in side them. But it didn't took that line as there are only empty spaces. Currently I'm adding a dot in the Text widget to get spaces. Is there any other way to do that?

This is the code I use to create the pdf.

QUESTION
I would like to implement a client-side shopping cart bound to the session history of the browser. It means that each item added to or removed from shopping cart should create a new session state, and going back or forward in the session history should affect the shopping cart accordingly.
To my knowledge, only the History API allows storing data in the session state (HTTP cookies and the Web storage API store data elsewhere in the browser). So here is a code snippet of a shopping page that allows the user to add items to his shopping cart, to interrupt his activity to go to the home page and resume it later, and to go back or forward in the session history with changes to the shopping cart:
...ANSWER
Answered 2021-May-27 at 20:26If it doesn't matter that different tabs can have different carts, or that closing a tab will destroy the cart, checkout the session storage api. It stores things in the session.
QUESTION
Task queues are sets, not queues, because step one of the event loop processing model grabs the first runnable task from the chosen queue, instead of dequeuing the first task.
This is mentioned on whatwg website Link and I am unable to understand that why set data structure is used instead of queue.

The thing I'm trying is a multipage react app where I can navigate between pages(like from the main route '/' to '/whitepape' or 'privacyPolicy'), but I have 4 different routes('/', 'services', 'features', 'contactUs') within the main route '/' which use react-scroll to get the scrolling between those 4 components whose links are added in the Navbar(this part works as expected).
But navigating between pages like replacing entirely all 4 components with whitepaper page or privacyPolicy page, with Navbar and Footer at the same place so that I can navigate back to home.
This is what I’m stuck at any help is appreciated I’m not sure I’m following the right way to implement what I need. I have been using React Navigation in react native which is simple to understand and straightforward, wish react-router was so straight forward instead react-router is a bit confusing.

Answered 2021-May-20 at 05:41Within the Switch
component path order and specificity matter. This isn't a detail that is overtly called out in their docs though. You want to order your more specific paths before less specific paths. Think of path
as more of a prefix, and you'll see that "/" is a path prefix for all paths.
The Switch
returns and renders the first matching path it finds in its children.
Just invert the order of your paths such that "/whitepaper"
is listed prior to the more general/less specific "/"
path.

If you're using Windows you can use Win API calls:

The HTML standard requires¹ the use of the UTF-8 encoding for HTML documents.
Does it permit the use of other encodings for externally loaded scripts?
...ANSWER
Answered 2021-Apr-20 at 17:05The HTML standard requires the use of the UTF-8 encoding for HTML documents
No, it doesn't. It prefers UTF-8, but you can use any other charset you want, as long as you declare it explicitly in an appropriate element. See Declaring character encodings in HTML.
Does it permit the use of other encodings for externally loaded scripts?
