Python Selenium 无头错误：元素不可交互

Question

I was making a program which scrapes info about stocks from the website https://www.tradingview.com/screener/ which used selenium.here is the code:

def stock(aaa):
    a=[]
    chrome_options = Options()
    custom_header = {'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/74.0.3729.169 Safari/537.36'}
    chrome_options.add_argument("--headless")
    chrome_options.add_argument(f"user-agent={custom_header}")
    chrome_options.add_argument("--disable-gpu")
   
    browser = webdriver.Chrome(options=chrome_options)
    browser.get("https://www.tradingview.com/screener/")
    entry=browser.find_element_by_css_selector("#js-screener-container > div.tv-data-table-sticky-wrapper.tv-screener-sticky-header-wrapper > table > thead > tr > th.tv-data-table__th.tv-data-table__cell.js-tv-data-table-th.js-tv-data-table-th-name.tv-data-table__sortable.tv-screener-table__sortable.tv-screener-table__th.js-draggable > div > div > div.tv-screener-table__search-query.js-search-query.tv-screener-table__search-query--without-description>input")
    entry.send_keys(aaa)

It was working well when it was not in headless mode,but when I switched to headless,it gave this error code:

File "c:\Users\██████\cowination.py", line 181, in <module>
    aaa=stock("zydus")
  File "c:\Users\██████\cowination.py", line 20, in stock
    entry.send_keys(aaa)
  File "C:\Users\████████████\Python39\lib\site-packages\selenium\webdriver\remote\webelement.py", line 477, in send_keys
    self._execute(Command.SEND_KEYS_TO_ELEMENT,
  File "C:\Users\████████████\Python39\lib\site-packages\selenium\webdriver\remote\webelement.py", line 633, in _execute
    return self._parent.execute(command, params)
  File "C:\Users\████████████\Python39\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 321, in execute
    self.error_handler.check_response(response)
  File "C:\Users\████████████\Python39\lib\site-packages\selenium\webdriver\remote\errorhandler.py", line 242, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.ElementNotInteractableException: Message: element not interactable
  (Session info: headless chrome=90.0.4430.212)

At first I thought it was because the window was not maximized as the entry box is not visible when not maximized.So I added the --start-maximized argument,but it too didn't work.I tried even Webdriverwait,but that to didn't work. So is there any way I can solve this problem? thanks in advance

Edit: I have written my code according to the correct answer.here is the code: from selenium import webdriver

from selenium.webdriver.chrome.options import Options
import time
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.action_chains import ActionChains

    a=[]

    chrome_options.add_argument("--headless")
    chrome_options.add_argument(f"user-agent={custom_header}")
    chrome_options.add_argument("--disable-gpu")
   
    browser = webdriver.Chrome(options=chrome_options)
    browser.get("https://www.tradingview.com/screener/")
    browser.maximize_window()
    time.sleep(3)

    return f"""Name of stock:{a[0]}

here is the output:

    Change value:15.60
    Rating:Buy
    Volume:210.603K
    Market Cap:12.656T
    Price to Earning Ratio:—
    EPS(TTM):—
    Sector:Energy Minerals

this is the expected output:

Name of stock:ZYDUS WELLNESS LTD.
        Last price:2110.15
        Change %:-0.57%
        Change value:-12.15

        Market Cap:134.251B
        Price to Earning Ratio:114.58
        EPS(TTM):18.52
        Sector:Consumer Non-Durables

Now it is typing in the search box but giving wrong output which is actually the info of the stock at the homepage and not that of the search results. Can anyone tell why it is happening?

Answer 1

Because you are using headless mode the send_keys won't work in this case. See also this post . When you remove headless option and replace the "zydus" with eg "aapl" everything works fine.

One ways to work this around in your specific case would be eg:

from selenium.webdriver.common.keys import Keys

browser.execute_script("$('.tv-screener-table__search-input.js-search-input').val('{}');".format(aaa))
action = webdriver.ActionChains(browser);
action.send_keys(Keys.SPACE).send_keys(Keys.BACKSPACE).perform()

This works exactly the same way as entry.send_keys(aaa)
