代码不起作用.我正试图用id号点击页面上的一个元素，但我不能

Question

我需要使用HTML代码中的元素ID来单击页面上的元素。这个按钮的ID是"；输入选项XXX"；其中XXX是介于100和400之间的3位数字。我想让python代码在页面上的HTML代码中运行，找出3位数(在100到400之间(是什么，这样它就可以点击它了。有什么帮助吗？

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):

driver.find_element_by_id(f'input-option{i}').click()

Answer 1

使用try。。。除块：

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

如果您试图确定存在哪些id，则：

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)
