from selenium importwebdriver

import time

import os

 

dr =webdriver.Firefox()

file_path = 'file:///' +os.path.abspath('checkbox.html')

dr.get(file_path)

 

# 选择所有的checkbox并全部勾上

 

checkboxes =dr.find_element_by_css_selector('input[type=checkbox]')

for check incheckboxes:

    check.click()

time.sleep(1)

 

# 打印当前页面上有多少个checkbox

 

 

dr.quit()

　　报错内容:TypeError: 'WebElement' object isnot iterable

解决办法:

checkboxes = dr.find_element_by_css_selector('input[type=checkbox]')

改为:

checkboxes = dr.find_elements_by_css_selector('input[type=checkbox]')

或者：input1 = dr.find_elements_by_tag_name('input')

注意：因为是定位一组元素，而不是单个元素，在书写时要特别注意；
