kandi X-RAY | polite Summary
The goal of polite is to promote responsible web etiquette. “bow and scrape” (verb): To make a deep bow with the right leg drawn back (thus scraping the floor), left hand pressed across the abdomen, right arm held aside. (idiomatic, by extension) To behave in a servile, obsequious, or excessively polite manner. [1] Source: Wiktionary, The free dictionary. The package’s two main functions bow and scrape define and realize a web harvesting session. bow is used to introduce the client to the host and ask for permission to scrape (by inquiring against the host’s robots.txt file), while scrape is the main function for retrieving data from the remote server. Once the connection is established, there’s no need to bow again. Rather, in order to adjust a scraping URL the user can simply nod to the new path, which updates the session’s URL, making sure that the new location can be negotiated against robots.txt. The three pillars of a polite session are seeking permission, taking slowly and never asking twice. The package builds on awesome toolkits for defining and managing http sessions (httr and rvest), declaring the user agent string and investigating site policies (robotstxt), and utilizing rate-limiting and response caching (ratelimitr and memoise).

QUESTION
What exactly is the [0] in this bit of code?
Why is it there?
What does it do?
Thank you!
...ANSWER
Answered 2022-Apr-16 at 01:46const form = document.getElementsByTagName('form')[0];
The form constant is using the "Get Elements By Tag Name" method for all of the "Form" tags in the document. Since this returns an array of elements, the [0] is specifying the element at Index 0 of the array.
In this case, it is only saving the first array element as the Form constant. Depending on whatever other code there is, it could be used to quickly refer to the HTML form instead of running a document query each time you want to use it.

QUESTION
I have been trying to add VO support in an area that loads some additional content after user clicks Show more button (refer the screenshots attached).
I need the VO to announce the info about additionally loaded elements, something like "What is a cookie? and 11 more items".
Tried:Method-1: used aria-live="polite" aria-relevant="additions"
- behavior: announces "What is a cookie?, Browse IT, button. "
Method-2: used role="alert"
- behavior: announces "What is a cookie?, Browse IT & 23 more items, alert, What is a cookie?, Browse IT, button."
How can I get it to announce the info about additionally added items?
Before Show-more clicked
...After Show-more is clicked
ANSWER
Answered 2021-Oct-27 at 15:30Sounds like it's mostly working. The key is using aria-live. Note that when you use role="alert", you get an implicit aria-live="assertive". I rarely use "assertive" or "alert" because that can cause other messages to be cleared. Stick with "polite".
You didn't say what you didn't like about method 1 or method 2. They're both announcing things. Do you want every tile that's added to be announced? I hope not. That's way too much information for the screen reader.
Originally you are showing 12 tiles. When you click "show more", another 12 tiles are added. What exactly do you want announced? As mentioned, you don't want the title of every tile announced. There's no need for that. I'd recommend just a simple "12 additional tiles added" or something like that.
If you have a blank aria-live container, you can put any text in there you want and that's exactly what will be announced.
Before "show more" is clicked on:

I have code that scrapes a website but does so in a way that after so many scrapes from a run, I get a 403 forbidden error. I understand there is a package in R called polite that does the work of figuring out how to run the scrape to the hosts requirements so the 403 won't occur. I tried my best at adapting it to my code but I'm stuck. Would really appreciate some help. Here is some sample reproducible code with just a few links from many:

QUESTION
Hi I wanna use a modal popup for Create User view in Asp Net Core 5 (mvc). I wanna use this modal as a ViewComponent In User Index view (which shows the list of users). I added a button that is related to Create User method.
I want when I click on that button the modal popup that is a ViewComponent opens.
but after running the application I cant go to Index User page, because of an exception that shows a conflict between the model used in Index.cshtml (which is IEnumerable) and the model used in ViewComponent View (which is UserViewModel).
I will upload the Exception.

Answered 2021-Dec-24 at 08:53InvalidOperationException: The model item passed into the ViewDataDictionary is of type 'System.Collections.Generic.List`1[ShopOnline.Domain.Entites.User]', but this ViewDataDictionary instance requires a model item of type 'ShopOnline.Web.ViewModel.UserViewModel'.
The above exception is clear, when you display the Default View Component, it requires a UserViewModel, instead of the List of User.
To solve the above issue, you could modify the CreateViewComponent as below:

Answered 2021-Dec-24 at 03:54If I simply use httr then I can pass in a valid UA header and re-write your code to instead use a data.frame call, instead of list, that way I can return N/A where value not present.
Swap out html_elements for html_element.
You also need to amend your xpaths to avoid getting the first node value repeated for each row.
