We are working on putting a large amount of string into the input box.

When working with Send_keys(), it takes too long to work.

Here is the method I found to solve this problem.

import pyperclip
from selenium.webdriver.common.keys import Keys
pyperclip.copy('foo')
element.send_keys(Keys.CONTROL, 'v')

This works very effectively, but returns an empty value in headless mode.

Is there any way to fix this in Heldless mode?

CodePudding user response：

Not sure which browser you are using or platform OS, but generally the OS does not allow headless browsers access/permissions to the OS clipboard or the browser dies not have a copy function set in headless mode.

As you have already identified the WebElement, you should try using the Javascript method, so in your case:

driver.execute_script('element.value="TestText";')

or

driver.execute_script('element').setAttribute('value','TestText');

Effectively the Javascript method is passing your content (in example above 'Testtest') into the element you have defined using the .value function.

I see there are already several questions about this issue are existing on Stackoverflow.
First - please try this solution suggesting using klembord instead of pyperclip:

from selenium import webdriver
from selenium.webdriver.firefox.options import Options
from webdriver_manager.firefox import GeckoDriverManager
import klembord
klembord.init()
options = Options()
options.headless = True
driver = webdriver.Firefox(options=options,executable_path=GeckoDriverManager().install())
print("Headless Firefox Initialized. Wait for output")
driver.get("https://www.lipsum.com")
l = driver.find_element_by_xpath("/html/body/div/div[2]/div[2]/div[3]/div[1]/p")
klembord.set_text(l.text) # setting text to clipboard
print("Check clipboard by pressing WIN   V or CTRL  V")
driver.quit()

Another attempt to overcome with issue, but in Java is here:
