我的 if/else 表达式不起作用我不知道为什么？

Question

My code:

website = browser.find_element_by_link_text('Website')

if website:
    website.click()
else:
    print('no website')

What I am trying to do is click the button if it is available on the page. If the button isn't available I want it to print no website available on the console and proceed to the next step.

I do not know what I am doing wrong does anyone know how to do fix this?

Thanks in advance I am new to coding!

Answer 1

Before you find an element, you need first visit a website.

driver = webdriver.Firefox()
print('Acessando web site: {}'.format(os.getenv('VISIT_URL')))
driver.get('www.example.com')
#here onwards you can access browser elements like buttons links etc

Answer 2

You are giving a instance of Web element to if() condition, where a boolean expression is expected.

1) Try checking the presence first using find_elements_by_link_text() # _elements_

if len(driver.find_elements_by_link_text('Website')) > 0: 
    driver.find_element_by_id('Website').click()

2) Or use expected_conditions to check whether the element is available; expected_conditions documentation

3) Or use try/except block;

    try:
        website = driver.find_elements_by_link_text('Website')
    except NoSuchElementException:
        # code to execute if the expected element is not available
