我正在努力写出自己的预期条件.我需要什么...我有一个iframe.我也有一个图像.我想在图像的scr改变时继续处理.我做了什么:

class url_changed_condition(object):
    '''
    Checks whether url in iframe has changed or not
    '''
    def __init__(self, urls):
        self._current_url, self._new_url = urls

    def __call__(self, ignored):
        return self._current_url != self._new_url  

后来在我的代码中:

def process_image(self, locator, current_url):
    try:
        WebDriverWait(self.driver, 10).until(ec.presence_of_element_located((By.TAG_NAME, u"iframe")))
        iframe = self.driver.find_element(*locator)
        if iframe:
            print "Iframe found!"
        self.driver.switch_to_frame(iframe)
        WebDriverWait(self.driver, 10).until(ec.presence_of_element_located((By.XPATH, u"//div")))

        # WebDriverWait(self.driver, 10).until(
            # url_changed_condition(
                # (current_url, self.driver.find_element(By.XPATH, u"//a/img").get_attribute(u"src"))))

        img_url = self.driver.find_element(By.XPATH, u"//a/img").get_attribute(u"src")
        print img_url
        self.search_dict[self._search_item].append(img_url)
        self.driver.switch_to_default_content()
    except NoSuchElementException as NSE:
        print "iframe not found! {0}".format(NSE.msg)
    except:
        print "something went wrong" …

这是我第一次在 stackoverflow 上发帖，我对 Selenium 和 Python 还有些陌生。

当 URL 等于 fx: https://www.example.com时，我不希望运行函数。

我在另一个讨论中读过 这个答案，但我不太明白发生了什么。

我希望您能抽出时间回答我的问题。

好的，所以我刚刚尝试过这个：

driver.get('https://www.google.com')
time.sleep(4)
driver.get('https://www.stackoverflow.com')

if WebDriverWait(driver, 10).until(EC.url_to_be('https://stackoverflow.com')):
    print('Desired url was rendered within allocated time')
else:
    print('Desired url was not rendered within allocated time')

但这没有用。有任何想法吗？
