检查元素是否存在

Question

def status_button_check():
    if(driver.find_element_by_xpath("//div[@role='button' and @title='Status']")):
        s_b_c_status = "True"
    else:
        s_b_c_status = "False"
    print(s_b_c_status)
status_button_check()

试图检查元素是否存在，但这给了我以下错误：

  

selenium.common.exceptions.NoSuchElementException：消息：没有这样的消息   元素：无法找到元素：   “ method”：“ xpath”，“ selector”：“ // div [@ role ='button'和   @ title ='状态']“}

Answer 1

错误消息...

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: "method":"xpath","selector":"//div[@role='button' and @title='Status']"}

...表示您使用的 XPath 无法在HTML DOM中找到任何元素。

如果要验证所需元素的存在，则需要按以下步骤引发try-catch{}块：

def status_button_check():
    try:
        if(driver.find_element_by_xpath("//div[@role='button' and @title='Status']")):
            s_b_c_status = "True"
    except NoSuchElementException:
            s_b_c_status = "False"
    print(s_b_c_status)
status_button_check()

Answer 2

编写此代码

def status_button_check():
    if(driver.find_elements_by_xpath("//div[@role='button' and @title='Status']")>0):
        s_b_c_status = "True"
    else:
        s_b_c_status = "False"
    print(s_b_c_status)
status_button_check()
