如何在 python 中使用 selenium 将整个文本发送到文本区域而不是逐行发送？

Question

我的代码将文本逐行输入到网页的文本区域，如何让它一次插入整个文本，有没有解决方案？ 因为一行一行需要很多时间

def Translated_Content(content):

    driver= webdriver.Chrome("C:\\Users\\shricharan.arumugam\\Desktop\\PDF2txt\\chromedriver.exe")
    driver.get('https://translate.shell.com/')

    input_box = driver.find_element_by_id('translateText')
    input_box.send_keys(content)

    translate_button = driver.find_element_by_id('translate')
    translate_button.click()
    translated_text_element= driver.find_element_by_id('translatedText')
    time.sleep(4)


    translated_text=translated_text_element.get_attribute('value')

    driver.close()

    return translated_text

要通过 Python 使用 selenium 将整个文本块发送到 <textarea> 以加快进程，您可以注入脚本并使用以下解决方案：

• 代码块：

  from selenium import webdriver
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.support import expected_conditions as EC
  
  myText = """No, there is no way to hide the console window of the chromedriver.exe 
      in the .NET bindings without modifying the bindings source code. This is seen 
      as a feature of the bindings, as it makes it very easy to see when your code 
      hasn't correctly cleaned up the resources of the ChromeDriver, since the console window 
      remains open. In the case of some other languages, if your code does not properly clean up 
      the instance of ChromeDriver by calling the quit() method on the WebDriver object, 
      you can end up with a zombie chromedriver.exe process running on your machine.""" 
  options = webdriver.ChromeOptions() 
  options.add_argument("start-maximized")
  options.add_argument('disable-infobars')
  driver=webdriver.Chrome(chrome_options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
  driver.get('https://translate.shell.com/')
  translate_from = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "textarea.form-control#translateText")))
  translate_from._parent.execute_script("""
      var elm = arguments[0], text = arguments[1];
      if (!('value' in elm))
        throw new Error('Expected an <input> or <textarea>');
      elm.focus();
      elm.value = text;
      elm.dispatchEvent(new Event('change'));
      """, translate_from, myText)
  driver.find_element_by_css_selector("input#translate").click()

您可以通过 JavaScript DOM API 以静默方式更改 textbox/textarea 的文本，而不是从前端 UI：

long_string= <the long string>
input_box = driver.find_element_by_id('translateText')
driver.execute_script('arguments[0].value=arguments[1]', input_box, long_string)
