  • Select API 知识点

    1. select_by_index() 根据索引选择，0是第一个元素
      select_by_value() 根据value属性的值选择
      select_by_visible_text() 根据可见文本选择;不要写前后的空格

    2. deselect_by_index(index) 取消选择，0是第一个元素
      deselect_by_value(value) 根据value属性的值取消选择
      deselect_by_visible_text(text) 根据可见文本取消选择;不要写前后的空格
      deselect_all() 全部取消选择

  • 案例
    • select.html 
      <!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
   <div id="div1">
        <!--  select 下拉框      -->
        <select name="sex" id="gender">
            <option value=" male"> male</option>
            <option value="female">female</option>
            <option value="tailand">tailand</option>
        </select>
        <!--  select标签多选，通过multiple属性      -->
        <select name= “education” id=”education” multiple=”multiple”>
            <option value=”1”>高中</option>
            <option value=”2”>大学</option>
            <option value=”3”>博士</option>
            <option value=”4”>硕士</option>
        </select>
    </div>
</body>
</html>
    • ele_select.py 
      # -*- coding: UTF-8 -*-
import os
from time import sleep

from selenium.webdriver.support.select import Select
from selenium import webdriver

driver = webdriver.Chrome('../chromedriver.exe')
driver.get(os.path.abspath('select.html'))

test_flag = 3
if test_flag == 1:
    driver.find_element('css selector', '#gender>option:nth-child(2)').click()  # 不用API,可以直接点
if test_flag == 2:
    ele_select = driver.find_element('css selector', '#gender')
    Select(ele_select).select_by_index(1)  # female
    sleep(2)
    Select(ele_select).select_by_value('tailand')  # tailand
    sleep(2)
    # xpath = ".//option[normalize-space(.) = %s]" % self._escape_string(text) 源码中normalize-space去除首尾空格
    Select(ele_select).select_by_visible_text('male')
if test_flag == 3:
    ele_select = driver.find_element('css selector', '#”education”')
    Select(ele_select).select_by_index(0)
    sleep(2)
    Select(ele_select).select_by_index(1)
    sleep(2)
    Select(ele_select).deselect_by_index(0)
    Select(ele_select).deselect_all()
    sleep(2)
    # Select(ele_select).deselect_by_value('')
    # sleep(2)
    # Select(ele_select).deselect_by_visible_text('')

      注意：根据可见文本选择时，若元素中含有空格不需要写，因为在源码中normalize-space已去除首尾空格
