selenium webdriver python 元素定位

总结

 

定位查找时，返回查找到的第一个match的元素。如果找不到，则 raise NoSuchElementException

 

单个元素定位：

find_element_by_id
find_element_by_name
find_element_by_xpath
find_element_by_link_text
find_element_by_partial_link_text
find_element_by_tag_name
find_element_by_class_name
find_element_by_css_selector

多个元素定位：

find_elements_by_name
find_elements_by_xpath
find_elements_by_link_text
find_elements_by_partial_link_text
find_elements_by_tag_name
find_elements_by_class_name
find_elements_by_css_selector

其他定位方法（属于Page Object的private方法）：

from selenium.webdriver.common.by import By

driver.find_element(By.XPATH, '//button[text()="Some text"]')
driver.find_elements(By.XPATH, '//button')

其中，By可以是：

ID = "id"
XPATH = "xpath"
LINK_TEXT = "link text"
PARTIAL_LINK_TEXT = "partial link text"
NAME = "name"
TAG_NAME = "tag name"
CLASS_NAME = "class name"
CSS_SELECTOR = "css selector"

具体

1. id

driver.find_element_by_id(‘userid’)

2. name

driver.find_element_by_name(‘username’)

3. tagName

driver.find_element_by_tag_name(“input”)

4. class Name

driver.find_element_by_class_name(“nv”)

5. link text 

driver.find_element_by_link_text(“关于百度”)

6. partial link text

driver.find_element_by_partial_link_text(“关于”)

7.CSS selector

driver.find_element_by_css_selector(“a[name=”tj_news”]”)

 

8. xpath

driver.find_element_by_xpath(“//input[@id=‘kw’]”)

 

9. 层级定位

menu = driver.find_element_by_id('dropdown1').find_element_by_link_text('Action')

10. 定位一组元素

inputs=driver.find_elements_by_tag_name(‘input’)

11. 定位最后一个元素

driver.find_elements_by_css_selector(‘input[type=checkbox]’).pop().click
