代码不起作用。 我试图点击页面上带有 id 号的元素，但我不能

Question

I need to click an element on a page by using its ID from the HTML code. The ID of this button is "input-optionXXX" where XXX is a 3 digit number between 100 and 400. I want the python code to run through the HTML code on the page and find out what the 3 digit number (between 100 and 400) is so it can click on it. Any help?

a = list(range(100,400))
for i in a:
    if EC.presence_of_element_located((By.ID, f'input-option{str(i)}')):
        driver.find_element_by_id(f'input-option{i}').click()
        print(i)

Traceback (most recent call last):

Answer 1

Use try...except block:

from selenium.common.exceptions import NoSuchElementException

for i in range(100, 400):
    try:
        driver.find_element_by_id(f'input-option{i}').click()
        print(i)
    except NoSuchElementException:
        continue

Answer 2

If you are trying to determine which ids are present, then:

for i in range(100, 400):
    # The following might return an empty list but should not throw an exception:
    elements = driver.find_elements_by_id(f'input-option{i}')
    if elements:
        elements[0].click()
        print(i)
