Selenium(三)：瀏覽器大小和位置

一、知識點：

maximize_window()
fullscreen_window()
minimize_window()
set_window_size()
get_window_size()
set_window_position()
get_window_position()
set_window_rect()
get_window_rect()

## 二、示例：瀏覽器大小和位置.py ``` # encoding:utf-8 from selenium import webdriver from time import sleep

1、打開 谷歌瀏覽器

driver = webdriver.Chrome()

2、最大化瀏覽器

driver.maximize_window()
sleep(2)

3、瀏覽器全屏化

driver.fullscreen_window()
sleep(2)

4、最小化瀏覽器

driver.minimize_window()
sleep(2)

5、設置瀏覽器大小為800*600

driver.set_window_size(800, 600)
sleep(2)

6、獲取瀏覽器大小

window_size = driver.get_window_size()
print('瀏覽器大小:', window_size)
sleep(2)

7、設置瀏覽器位置

driver.set_window_position(720, 400)
sleep(2)

8、獲取瀏覽器位置

window_position = driver.get_window_position()
print('瀏覽器位置:', window_position)
sleep(2)

9、設置瀏覽器的大小 600*400 和位置 600，500

driver.set_window_rect(x=600, y=500, width=600, height=400)
sleep(2)

10、獲取瀏覽器的大小和位置

size_and_position = driver.get_window_rect()
print('瀏覽器的大小和位置:', size_and_position)
