PYTHON-SELENUM3 fifth day positioning--infrequently used positioning and CSS positioning details

use tag to locate
Tag is labeled, not commonly used
For example: Baidu's input box tag is input
will eventually error, because Baidu Home input tag too much

driver = webdriver.Firefox(executable_path="d:\\geckodriver")driver.get("https://www.baidu.com")driver.find_element_by_tag_name("input").send_Keys("123")

Using link
Link hyperlink positioning, such as Baidu's hao123 href = "http://www.hao123.com

driver = webdriver.Firefox(executable_path="d:\\geckodriver")driver.get("https://www.baidu.com")driver.find_element_by_link_text("hao123").click()driver.back()driver.find_element_by_partial_link_text("123").click()

Explain the difference between link_text and Partial_link_text, sometimes the name is too long, partial_link is can be fuzzy positioning

CSS Positioning
As with XPath, CSS is based on the CSS derivation to locate the basic wording and CSS consistent with the wording such as:

The most common id,class, labels, take Baidu as an example
The CSS uses the # number to denote the id attribute, such as: #kw
CSS uses. Represents the class attribute, such as:. S_ipt
CSS directly with the tag name, without any identifiers, such as: input

driver = webdriver.Firefox(executable_path = "d:\\geckodriver")driver.get("https://www.baidu.com")driver.find_element_by_css_selector("#kw").send_keys("1")driver.find_element_by_css_selector(".s_ipt").send_keys("2")driver.find_element_by_css_selector("input").send_keys("3")

Other properties can be written directly
For example: The Name property and the AutoComplete property

driver.find_element_by_css_selector("[name=‘wd‘]").send_keys("4")driver.find_element_by_css_selector("[autocomplete=‘off‘]").send_keys("5")

Written by tag and element combination
For example:

driver.find_element_by_css_selector("input.#kw").send_keys("6")driver.find_element_by_css_selector("input.[id=‘kw‘]").send_keys("7")

Through level positioning

#xpath中的 xpath：//form[@id=‘form‘]/span/input 和 //form[@class=‘fm‘]/span/input 用css来编写driver.find_element_by_css_selector("form#form>span>input").send_keys("8")driver.find_element_by_css_selector("form.fm>span>input").send_keys("9")

Index: Positioning

The same label can be positioned by Option:nth-child (1).

driver = webdriver.Firefox(executable_path="d:\\geckodriver")driver.get("file:///G:/%E6%A1%8C%E9%9D%A2/20180329/%E7%AC%AC%E4%BA%8C%E9%98%B6%E6%AE%B5/HTML/day8.html")driver.find_element_by_css_selector("select#zz>option:nth-child(1)").click()driver.find_element_by_css_selector("select#zz>option:nth-child(2)").click()driver.find_element_by_css_selector("select#zz>option:nth-child(3)").click()

Logical Operation positioning
Multiple elements can be positioned at the same time, enhanced positioning, and XPath is not the same, can not write and

driver = webdriver.Firefox(executable_path = "d:\\geckodriver")driver.get("https://www.baidu.com")driver.find_element_by_css_selector("input[name=‘wd‘][autocomplete=‘off‘]").send_keys("1")

Unfortunately, there is no fuzzy matching for CSS now.
