即使元素不存在，Selenium也会继续脚本

Question

这是我的代码当前外观的一个示例

driver.find_element(By.ID, "FirstName").send_keys("MyFirstName")
driver.find_element(By.ID, "LastName").send_keys("MyLastName")
driver.find_element(By.ID, "PhoneNumber").send_keys("myPhoneNumber")
driver.find_element(By.ID, "Email").send_keys("myEmail")

例如，当元素ID“PhoneNumber”不存在时，脚本将以错误代码“无法定位元素”停止，需要添加或更改什么才能继续脚本而不中断，即使某个元素不存在

提前谢谢

Answer 1

您可以实现try/except块

from selenium.common.exceptions import NoSuchElementException

...
driver.find_element(By.ID, "LastName").send_keys("MyLastName")
try:
    driver.find_element(By.ID, "PhoneNumber").send_keys("myPhoneNumber")
except NoSuchElementException:
    print("No Phone number input field found")
driver.find_element(By.ID, "Email").send_keys("myEmail")
...

或使用条件运算符，如下所示：

if driver.find_elements(By.ID, "PhoneNumber"):
    driver.find_element(By.ID, "PhoneNumber").send_keys("myPhoneNumber")

Answer 2

您应该能够使用try语句，它如下所示：

try:
    driver.find_element(By.ID, "FirstName").send_keys("MyFirstName")
except:
    print("Element not found")

try:
    driver.find_element(By.ID, "LastName").send_keys("MyLastName")
except:
    print("Element not found")

try:
    driver.find_element(By.ID, "PhoneNumber").send_keys("myPhoneNumber")
except:
    print("Element not found")

try:
    driver.find_element(By.ID, "Email").send_keys("myEmail")
except:
    print("Element not found")

它应该打印出“未找到元素”，然后继续脚本
