JSON stringified object doesn't add in list [duplicate]

Question

I am trying to add JSON object to an array, but the "bookList" remain empty.

var bookList = []; 
for (var i = 0; i < idsArr.length; i++) {
    const book = getBook(idsArr[i]).then(book => {return book});
    book.then(function(result) {
      bookList.push(result);
    });
  }

result of getBook function:

{"id":1,"ownerId":9,"author":"Aleksandar Lekov","description":"My book part 4","price":15.99,"createdAt":"2022-04-20T09:37:20.252Z","updatedAt":"2022-04-20T09:37:20.252Z"}

getBook function:

async function getBook(id) {
  try {
    const audiobook = await Audiobook.findOne({
      where: { 
        id: id
      },
      raw: true,
    });
    return JSON.stringify(audiobook);
  }
  catch (err) {
    console.log(err, "can't find books by id");
  }
}

Answer 1

The getBook() is an asynchronous call.

bookList = [];

for (var i = 0; i < idsArr.length; i++) {
   getBook(idsArr[i]).then(book => {
      bookList.push(book);
   }).then(console.log); // <-- this should have the books
}

console.log(bookList) // <-- this is empty

So the bookList will be empty when you try to access it right after the for block.

Answer 2

Try having a look at switch_to_frame, see:

https://selenium-python.readthedocs.io/navigating.html#moving-between-windows-and-frames

iframe = driver.find_element_by_css_selector("iframe")
driver.switch_to_frame(iframe)

elem = driver.find_element_by_css_selector("#user")

Answer 3

As far I can see, there is no need to switch the frame since this element is out of it.

I couldn't validate my idea, since the HTML code you placed isn't interactable.

I've modified the HTML setting up a default value in this item and it's not giving the value, however, I'm able to get the position and others values from this web element. I would advise to remove the switch method and then double check.

import time
from selenium import webdriver
from selenium.webdriver.common.by import By

driver = webdriver.Chrome('chromedriver.exe')  # Optional argument, if not specified will search path.
try:
    driver.get('C:\\Users\\user\\IdeaProjects\\chrome-selenium-python\\index.html')
    time.sleep(2)  # Let the user actually see something!

    ele = driver.find_element(By.CSS_SELECTOR, "#user")
    ele.send_keys("Example")
    time.sleep(2)  
    print("Location", ele.location)
    print("Tag", ele.tag_name)
except Exception as a:
    print(a)
finally:
    driver.quit()

Answer 4

wait=WebDriverWait(driver,30)                                 
wait.until(EC.presence_of_element_located((By.ID,"id"))).send_keys('user')

Try for presence.
