checkbox.html源码:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40

　　Python代码:

 

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 21

#coding=utf-8   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；
