如何使用 Selenium/Webdriver 提示输入并使用结果?

问题描述

我想允许用户输入并根据它做出一些决定.如果我这样做:

I would like to allow for user input and make some decisions based on it. If I do this:

driver.execute_script("prompt('Enter smth','smth')")

我得到了一个很好的提示，但我不能使用它的值.有没有办法向用户显示输入框，并使用输入的值?

I get a nice prompt, but I cannot use it's value. Is there any way of showing an input box to the user, and use the value typed there?

这是我的脚本:

from selenium.webdriver import Firefox

if __name__ == "__main__":
    driver = Firefox()
    driver.execute_script("window.promptResponse=prompt('Enter smth','smth')")
    a = driver.execute_script("var win = this.browserbot.getUserWindow(); return win.promptResponse")
    print "got back %s" % a

这会以以下异常退出:

    a = driver.execute_script("var win = this.browserbot.getUserWindow(); return win.promptResponse")
  File "c:\python26\lib\site-packages\selenium-2.12.1-py2.6.egg\selenium\webdriver\remote\webdriver.py", line 385, in ex
ecute_script
    {'script': script, 'args':converted_args})['value']
  File "c:\python26\lib\site-packages\selenium-2.12.1-py2.6.egg\selenium\webdriver\remote\webdriver.py", line 153, in ex
ecute
    self.error_handler.check_response(response)
  File "c:\python26\lib\site-packages\selenium-2.12.1-py2.6.egg\selenium\webdriver\remote\errorhandler.py", line 110, in
 check_response
    if 'message' in value:
TypeError: argument of type 'NoneType' is not iterable

我做错了什么?

我试着像 prestomanifesto 建议的那样做，这是输出:

I tried to do like prestomanifesto suggested, here's the output:

In [1]: from selenium.webdriver import Firefox

In [2]: f = Firefox()

In [3]: a = f.ex
f.execute              f.execute_async_script f.execute_script

In [3]: a = f.execute_script("return prompt('Enter smth','smth')")

In [4]: a
Out[4]: {u'text': u'Enter smth'}

In [5]: a
Out[5]: {u'text': u'Enter smth'}

In [6]: class(a)
  File "<ipython-input-6-2d2ff4f61612>", line 1
    class(a)
         ^
SyntaxError: invalid syntax


In [7]: type(a)
Out[7]: dict

推荐答案

希望这对其他人有帮助:

Hope this helps others:

# selenium (3.4.1)  python (3.5.1)
driver.execute_script("var a = prompt('Enter Luffy', 'Luffy');document.body.setAttribute('data-id', a)")
time.sleep(3)  # must 
print(self.driver.find_element_by_tag_name('body').get_attribute('data-id'))   # get the text
