Question

我谨允许用户提出意见,并根据这些意见作出一些决定。如果我这样做的话:

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

我听到了一点,但我不能利用它的价值。是否有任何办法向用户显示输入箱,并使用该箱的数值?

EDIT:这是我的文字:

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

除以下例外:

    a = driver.execute_script("var win = this.browserbot.getUserWindow(); return win.promptResponse")
  File "c:python26libsite-packagesselenium-2.12.1-py2.6.eggseleniumwebdriver
emotewebdriver.py", line 385, in ex
ecute_script
    { script : script,  args :converted_args})[ value ]
  File "c:python26libsite-packagesselenium-2.12.1-py2.6.eggseleniumwebdriver
emotewebdriver.py", line 153, in ex
ecute
    self.error_handler.check_response(response)
  File "c:python26libsite-packagesselenium-2.12.1-py2.6.eggseleniumwebdriver
emoteerrorhandler.py", line 110, in
 check_response
    if  message  in value:
TypeError: argument of type  NoneType  is not iterable

我没有做什么?

EDIT:我试图像预告那样做,这里的产出是:

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

Answer 1

希望有助于其他人:

# 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

Answer 2

You are correct in using the prompt box in javascript. But the prompt box value should be assigned to a global variable and then you could use this variable later. something like this:

driver.execute_script(”window.promptResponse=prompt() 加入:

and then retrieve the value from the same global variable.

a = driver.execute_script("var win = this.browserbot.getUserWindow(); return win.promptResponse")

你们也许需要放弃回报。

Hope this helps.

我知道这是一个老的问题,但我也存在同样的问题,这对我来说是什么事:有些信贷到@Devin。

from selenium.common.exceptions import UnexpectedAlertPresentException

while True:
    try:
        driver.execute_script("var a = prompt( Enter Luffy ,  Luffy );document.body.setAttribute( user-manual-input , a)")
        sleep(5)  # must 
        print(driver.find_element_by_tag_name( body ).get_attribute( user-manual-input )) # get the text
        break

     except (UnexpectedAlertPresentException):
        pass

很快将等待5秒的投入。如果没有投入,将促使用户再次提供投入。

Tkinter是一个基于全球倡议的图书馆,你可以在操作时间从用户那里获取信息。除非用户输入信息,否则该方案将持续等待。关于预先设计的对话箱,请参阅link。虽然它很晚,但它可能帮助别人。

Answer 5

根据其他答复,我制定了以下法典,为我工作:


def is_alert_present(driver):
    try:
        driver.switch_to.alert
        return True
    except exceptions.NoAlertPresentException:
        return False


def prompt_user(driver, text):

    driver.execute_script( var a = prompt ("{}");document.body.setAttribute("data-id", a) .format(text))
    while is_alert_present(driver):
        sleep(4)
    v = driver.find_element_by_tag_name( body ).get_attribute( data-id )

    return v if v !=  null  else None

Answer 6

为什么不能直接收回价值?

if __name__ == "__main__":
    driver = Firefox()
    a = driver.execute_script("return prompt( Enter smth , smth )")
    print "got back %s" % a

我在C#中的工程。诚然,它含有略为老的硫化物,但我 would期望<代码>execute_script功能大为改变。

您可使用所建议的技术https://stackoverflow.com/a/8532999/1077279>。

基本思想是:

Issue Selenium commands up to the point where you want to capture user input.
Get the user input in the console window with raw_input()
Continue your Selenium commands

In Python for instance:

#Navigate to the site
driver.Navigate().GoToUrl("http://www.google.com/")
#Find the search box on the page
queryBox = self.driver.FindElement(By.Name("q"))
#Wait for user text input in the console window
text = raw_input("Enter something")
#Send the retrieved input to the search box
queryBox.SendKeys(text)
#Submit the form
queryBox.Submit()

Answer 8

如果你用ium2.28像我这样说的话,那么就象@Baz1nga这样trick。

//Open the prompt inbox and setup global variable to contain the result
WebDriver driver = new FirefoxDriver();
JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("window.promptResponse = prompt("Please enter captcha");");

//Handle javascript prompt box and get value. 
Alert alert = driver.switchTo().alert();
try {
  Thread.sleep(6000);
} catch (Exception e)
{
  System.out.println("Cannot sleep because of headache");
}
alert.accept();
String ret = (String) js.executeScript("return window.promptResponse;");
