Python selenium PO By.XPATH定位元素報錯

Python selenium PO  By.XPATH定位元素報錯

如下代碼經常報錯：

    # 首頁的“新建投放計划”按鈕
    new_ads_plan = (By.XPATH, "//*[text()='百度新聞']/..") print(type(self.new_ads_plan)) self.driver.find_element(self.new_ads_plan).click()

運行經常報錯：
selenium.common.exceptions.WebDriverException: Message: invalid argument: 'using' must be a string

 

解決辦法：

self.driver.find_element(*self.new_ads_plan).click()

在參數里面的元素定位 self 前加一個星號 *

    new_ads_plan = (By.XPATH, "//*[text()='百度新聞']") shouye = (By.XPATH, "//a[text()= '首頁']") zanTing = (By.XPATH, "//span[text()= '刪 除']") bianji = (By.XPATH, "//span[text()= '編 輯']") addSuCai = (By.XPATH, "//span[text()= '添加']") def isElementExists(self, *loc): flag = True try: for num in range(0, len(loc)): print(str(loc[num])) self.driver.find_element(*loc[num]) return flag except: flag = False return flag # 判斷元素是否顯示
    def is_ElementExists(self): return self.isElementExists((self.new_ads_plan),  (self.shouye), (self.zanTing), (self.bianji), (self.addSuCai)) 
 
 # 此處必須將多個定位元素的入參以元祖的形式填入，每一個元素的定位參數都是一個數組。
