python - 调用ActionChains move_to_element()会导致属性错误？

运行python / selenium脚本时出现以下错误：

AttributeError：“ WebElement”对象没有属性“ move_to_element”

此特定错误消息说明了什么？是否无法将move_to_element识别为有效动作？我正在这样导入actionchains模块：

from selenium.webdriver.common.action_chains  import ActionChains

我能够使用click（）和send_keys（）操作而不会出现问题。

def wait_for_element_visibility(self, waitTime, locatorMode, Locator):
     element = None
     if   locatorMode == LocatorMode.ID:
          element = WebDriverWait(self.driver, waitTime).\
                  until(EC.visibility_of_element_located((By.ID, Locator)))
     elif locatorMode == LocatorMode.NAME:
          element = WebDriverWait(self.driver, waitTime).\
                  until(EC.visibility_of_element_located((By.NAME, Locator)))
     elif locatorMode == LocatorMode.XPATH:
          element = WebDriverWait(self.driver, waitTime).\
                  until(EC.visibility_of_element_located((By.XPATH, Locator)))
     elif locatorMode == LocatorMode.CSS_SELECTOR:
          element = WebDriverWait(self.driver, waitTime).\
                  until(EC.visibility_of_element_located((By.CSS_SELECTOR, Locator)))
     else:
         raise Exception("Unsupported locator strategy.")
     return element

 def find_element(self, locatorMode, Locator):
     element = None
     if locatorMode == LocatorMode.ID:
        element = self.driver.find_element_by_id(Locator)
     elif locatorMode == LocatorMode.NAME:
        element = self.driver.find_element_by_name(Locator)
     elif locatorMode == LocatorMode.XPATH:
        element = self.driver.find_element_by_xpath(Locator)
     elif locatorMode == LocatorMode.CSS_SELECTOR:
        element = self.driver.find_element_by_css_selector(Locator)
     else:
        raise Exception("Unsupported locator strategy.")
     return element

 def fill_out_field(self, locatorMode, Locator, text):
     self.find_element(locatorMode, Locator).clear()
     self.find_element(locatorMode, Locator).send_keys(text)

 def click(self, waitTime, locatorMode, Locator):
    self.wait_until_element_clickable(waitTime, locatorMode, Locator).click()

 def hover_over(self, waitTime, locatorMode, Locator):
     element = Locator
     self.wait_for_element_visibility(waitTime, locatorMode, Locator).move_to_element(element).perform()

我试图这样称呼它：

self.hover_over(10,
                        "id",
                        WelcomePageMap['ShareButtonId']
        )

最佳答案

这是问题所在的行：


  self.wait_for_element_visibility(waitTime, locatorMode, Locator).move_to_element(element).perform()


在这里，wait_for_element_visibility()等待元素的可见性并返回元素本身，然后，您在move_to_element()对象上调用WebElement，但是，您需要在ActionChains实例上调用它，将先前找到的元素传递为一个论点：

from selenium.webdriver.common.action_chains import ActionChains

element = self.wait_for_element_visibility(waitTime, locatorMode, Locator)

actions = ActionChains(self.driver)
actions.move_to_element(element)
actions.perform()
