如何设置浏览器视口大小

Question

我试图创建一个跨浏览器的Python-Selenium测试脚本。因此，无论我使用哪种WebDriver(Chrome或IE)，我都需要所有结果相同。我可以按以下方式设置浏览器窗口大小：

driver.set_window_size(1920, 1080)

element = driver.find_element_by_xpath('some_xpath')
element.location

driver.execute_script('return document.documentElement.clientHeight')
driver.execute_script('return document.documentElement.clientWidth')

driver.execute_script('document.documentElement.clientHeight = "990px";')
driver.execute_script('document.documentElement.clientWeight = "1900px";')

Answer 1

下面是设置视口大小的函数：

def set_viewport_size(driver, width, height):
    window_size = driver.execute_script("""
        return [window.outerWidth - window.innerWidth + arguments[0],
          window.outerHeight - window.innerHeight + arguments[1]];
        """, width, height)
    driver.set_window_size(*window_size)

用法：

from selenium import webdriver

driver = webdriver.Chrome()

# set the viewport size to 800 x 600
set_viewport_size(driver, 800, 600)

# display the viewport size
print driver.execute_script("return [window.innerWidth, window.innerHeight];")
