selenium 獲取按鈕的筆記

測試odoo時，發現大部分按鈕都是動態生成，id也是動態的，

只能用xpath，但是配置一旦改變導致按鈕位置改變

想到一個辦法，遍歷所有按鈕，然后內容相符的才點擊，測試代碼如下

submit_loc = (By.XPATH,"/html/body/div/div/form/div[3]/button")
self.find_element(*self.submit_loc).click()
login_value = self.find_element(*self.submit_loc).get_attribute("textContent")
print(login_value)

最后整理到基類里

    def click_button_byText(self, text):
        try:
            # WebDriverWait(self.driver, 10).until(EC.visibility_of_element_located(loc))
            # time.sleep(1)
            # return self.driver.find_elements(*loc)
            elements = self.find_elements('tag name', 'button')
            # print(type(submits))
            for i in elements:
                # print(type(i))
                print(i.get_attribute("textContent"))
                if i.get_attribute("textContent").find(text)>= 0:
                    i.click()
                    break
        except AttributeError:
            print(u"%s 頁面中未能找到 %s 元素" % (self, text))
