Selenium Getting Started: CSS positioning

Selenium strongly recommends using CSS positioning instead of XPath to locate elements, because CSS positioning is faster than XPath positioning and syntax is more concise.

CSS Common positioning method

1.find_element_by_css_selector ()

2. #id the ID selector to locate the element based on the id attribute

3.. class class selector, locating elements according to class attribute values

4. [attribute= ' value '] locates elements based on attributes

5.element>element to locate parent > child elements based on element level

Example:

From selenium import Webdriver

From time import sleep

Driver=webdriver. Firefox ()

Driver.get ("http://www.baidu.com")

#根据id定位

Driver.find_element_by_css_selector ("#kw"). Send_keys ("LoadRunner")

#根据class定位

Driver.find_element_by_css_selector (". S_ipt"). Send_keys ("VB")

#根据属性定位

Driver.find_element_by_css_selector ("[autocomplete= ' off ']"). Send_keys ("Selenium")

Sleep (3)

driver.find_element_by_id ("su"). Click ()

Sleep (5)

Driver.quit ()

Driver.get ("Http://www.***.net")

Sleep (2)

#根据层级定位

Driver.find_element_by_css_selector ("Form#loginform>u1>input"). Send_keys ("User name")

Driver.find_element_by_css_selector ("form#loginform>u1>input[name= ' password ')"). Send_keys ("password")
