保存记事本：drop_down.html，与python写的代码在同一个目录下
<html> <body> <select id="ShippingMethod" onchange="updateShipping(options[selectedIndex]);" name="ShippingMethod"> <option value="12.51">UPS Next Day Air ==> $12.51</option> <option value="11.61">UPS Next Day Air Saver ==> $11.61</option> <option value="10.69">UPS 3 Day Select ==> $10.69</option> <option value="9.03">UPS 2nd Day Air ==> $9.03</option> <option value="8.34">UPS Ground ==> $8.34</option> <option value="9.25">USPS Priority Mail Insured ==> $9.25</option> <option value="7.45">USPS Priority Mail ==> $7.45</option> <option value="3.20" selected="">USPS First Class ==> $3.20</option> </select> </body> </html>
选择￥10.69这项python代码如下
# -*- coding: utf-8 -*-
from selenium import webdriver
import time,os
dr=webdriver.Chrome()
file_path='file:///'+os.path.abspath('drop_down.html')
dr.get(file_path)
m=dr.find_element_by_id("ShippingMethod")
m.find_element_by_xpath("//option[@value='10.69']").click()
time.sleep(3)
dr.quit()
解析：
这里可能和之前的操作有所不同，首先要定位到下拉框的元素，然后选择下拉列表中的选项进行点击操作。
m=driver.find_element_by_id("ShippingMethod")
m.find_element_by_xpath("//option[@value='10.69']").click()
注：file_path='file:///'是完整的不需要在修改
