Python selenium PO By.XPATH定位元素报错

Python selenium PO  By.XPATH定位元素报错

如下代码经常报错：

    # 首页的“新建投放计划”按钮
    new_ads_plan = (By.XPATH, "//*[text()='百度新闻']/..") print(type(self.new_ads_plan)) self.driver.find_element(self.new_ads_plan).click()

运行经常报错：
selenium.common.exceptions.WebDriverException: Message: invalid argument: 'using' must be a string

 

解决办法：

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

在参数里面的元素定位 self 前加一个星号 *

    new_ads_plan = (By.XPATH, "//*[text()='百度新闻']") shouye = (By.XPATH, "//a[text()= '首页']") zanTing = (By.XPATH, "//span[text()= '删 除']") bianji = (By.XPATH, "//span[text()= '编 辑']") 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 # 判断元素是否显示
    def is_ElementExists(self): return self.isElementExists((self.new_ads_plan),  (self.shouye), (self.zanTing), (self.bianji), (self.addSuCai)) 

 # 此处必须将多个定位元素的入参以元祖的形式填入，每一个元素的定位参数都是一个数组。
