我要评论一、控制浏览器相关操作
1、控制浏览器窗口大小
全屏显示maximize_window()
from selenium import webdriver driver = webdriver.chrome() driver.implicitly_wait(3) #全屏显示 driver.maximize_window()
指定浏览器大小set_window_size(w, h)
#指定浏览器大小 driver.set_window_size(600,400)
2、控制浏览器前进forward()和后退back()
#前进 driver.forward() #后退 driver.back()
3、刷新refresh()
#刷新页面 driver.refresh()
4、窗口截屏
img_dir = "c:\\测试\\img.png" driver.save_screenshot(img_dir)
二、webdriver常用方法
| 序号 | 方法 | 描述 |
|---|---|---|
| 1 | clear() | 清除 |
| 2 | send_keys(“value”) | 输入内容 |
| 3 | click() | 点击事件 |
| 4 | submit() | 提交 |
| 5 | size | 元素尺寸 |
| 6 | text | 元素文本 |
| 7 | get_attribute() | 获取属性 |
| 8 | is_displayed() | 查看该元素是否用户可见 |
三、鼠标操作
| 序号 | 方法 | 描述 |
|---|---|---|
| 1 | click() | 鼠标点击事件 |
| 2 | move_to_element() | 鼠标悬停效果 |
| 3 | context_click() | 鼠标右击事件 |
| 4 | double_click() | 鼠标双击事件 |
| 5 | drag_and_drop() | 鼠标拖动事件 |
1、单击事件
from selenium import webdriver
from selenium.webdriver import actionchains
from selenium.webdriver.common.by import by
driver = webdriver.chrome()
driver.implicitly_wait(3)
driver.get("https://www.baidu.com")
driver.find_element(by.id,"kw").send_keys("单击事件")
element = driver.find_element(by.css_selector,'#su')
actionchains(driver).click(element).perform()
2、鼠标悬停
#鼠标悬停 actionchains(driver).move_to_element(element).perform()
3、鼠标右击事件
#鼠标右击击事件 actionchains(driver).context_click(element).perform()
4、鼠标双击事件
#鼠标双击事件 actionchains(driver).double_click(element).perform()
5、鼠标拖动事件
#鼠标拖动事件 tag = driver.find_element(by.css_selector,"#div1") actionchains(driver).drag_and_drop(element,tag).perform()
四、键盘相关操作
| 序号 | 方法 | 描述 |
|---|---|---|
| 1 | send_keys(keys.back_space) | 删除键（backspace） |
| 2 | send_keys(keys.space) | 空格键（space） |
| 3 | send_keys(keys.tab) | tab 键 |
| 4 | send_keys(keys.escape) | esc 键 |
| 5 | send_keys(keys.enter) | enter 回车键 |
| 6 | send_keys(keys.control,“a”) | ctrl+a | ctrl+c | ctrl+x | ctrl+v |
| 7 | send_keys(keys.f1) | f1~f12 |
以enter回车键为例演示
from selenium import webdriver
from selenium.webdriver.common.by import by
# 引入keys模块
from selenium.webdriver.common.keys import keys
driver = webdriver.chrome()
driver.get("https://www.baidu.com")
#键盘按键操作
element=driver.find_element(by.id,"kw")
element.send_keys("enter回车事件")
element.send_keys(keys.enter)
五、显示等待和隐式等待
from selenium import webdriver
from selenium.webdriver.common.by import by
from selenium.webdriver.support import expected_conditions
from selenium.webdriver.support.wait import webdriverwait
driver = webdriver.chrome()
#隐式等待
driver.implicitly_wait(3)
driver.get("https://www.baidu.com")
#显示等待
webdriverwait(driver,5,1).until(expected_conditions.visibility_of_element_located(by.id,"kw"))
