python - 如何使用 selenium 和 python 将文本插入输入标签

Question

我能够通过 this 所在的类名找到元素，但我不确定如何选择它本身并向它发送文本。

当前代码:

editor = browser.find_element_by_class_name('editor')
editor.send_keys('text')

我要选择的元素:

<input type="text" tabindex="103" placeholder="" style="width: 444px;">

错误:

File "C:\Python35\lib\site-packages\selenium\webdriver\remote\webelement.py", line 347, in send_keys
    self._execute(Command.SEND_KEYS_TO_ELEMENT, {'value': keys_to_typing(value)})
  File "C:\Python35\lib\site-packages\selenium\webdriver\remote\webelement.py", line 494, in _execute
    return self._parent.execute(command, params)
  File "C:\Python35\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 236, in execute
    self.error_handler.check_response(response)
  File "C:\Python35\lib\site-packages\selenium\webdriver\remote\errorhandler.py", line 192, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: unknown error: cannot focus element

您尝试选择的元素没有类名。尝试

from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

editor = WebDriverWait(browser, 10).until(EC.visibility_of_element_located((By.XPATH, '//input[@type="text"][@tabindex="103"]')))
editor.send_keys('text')
