Python selenium没有点击

Question

所以我在这里失去了理智。我想点击一个特定的按钮，但有一个我不明白的错误：

Traceback (most recent call last):
  File "C:\Users\leosc\PycharmProjects\ogameBot\guideline.py", line 22, in guideline
    if metalMineLVL() > (10):

    a = self.sparte()
  File "C:\Users\leosc\PycharmProjects\ogameBot\classes.py", line 54, in <lambda>
    (By.XPATH, ('//*[contains(text(),\'{}\')]').format(sparte))))

这里的代码：

self.sparte = lambda: wait.until(                   
    EC.presence_of_element_located(
    (By.XPATH, ('//*[contains(text(),\'{}\')]').format(sparte))))
self.LVL = lambda: int(
    wait.until(EC.presence_of_element_located((By.XPATH, ('//* 
    [@ref=\'' + str(ref) + '\']/span/span')))).text)

def checkLVL(self):

    time.sleep(1)
    self.sparte().click()
    time.sleep(1)
    return self.LVL()


    metalMineLVL = lambda: c.metalMine.checkLVL()
    roboFabLVL = lambda: c.roboFab.checkLVL()

    try:
        if metalMineLVL() > (10):
            if roboFabLVL() <(5):
                c.roboFab.build()
    except:
        pass

当我激活调试器时，我看到每个东西都被处理，直到它到达

self.sparte = lambda: wait.until(                   
    EC.presence_of_element_located(
    (By.XPATH, ('//*[contains(text(),\'{}\')]').format(sparte))))

然后它进入异常部分。但是我一直在程序的其余部分使用这行代码，通常它工作得很好。我做错了什么？提前致谢！！

Answer 1

我不知道你为什么会得到这个错误。我最好的猜测是，这是因为名称空间冲突，但我不确定。这是我用来点击内容的代码：

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

def clickElement(driver, XP):
    WebDriverWait(driver, 30).until(EC.visibility_of_element_located((By.XPATH, XP)))
    driver.find_element_by_xpath(XP).click()

例：

clickElement(driver, '/html/body/div[3]/div/a[1]')

另请查看PEP 498以获取字符串格式。

Answer 2

我现在发现问题是该程序打开了4个额外的选项卡，然后关闭了初始选项卡。通常情况下，我做了：

newTabs = c.driver.window_handles
        for tab in newTabs:
            c.driver.switch_to.window(tab)

让Selenium在新标签上工作。然而，编写新代码时，我忘了这样做，所以Selenium认为它仍然在初始标签上运行，该标签已经关闭。非常感谢!!
