selenium:select下拉框-Toy模板网

这篇具有很好参考价值的文章主要介绍了selenium:select下拉框。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

以下两种导的包没有任何本质区别。ui包就是调用Select包中的select方法。

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

**选择下拉选项：**select类提供了3种方法某一选项的方法，分别是：

通过index选择下拉选项——select_by_index(index);
通过value值选择下拉选项——select_by_value(value);
通过可见的text选择下拉选项——select_by_visible_text(text)。

**取消下拉选项：**select类提供了4种方法某一选项的方法，分别是：

通过index选择下拉选项——deselect_by_index(index);
通过value值选择下拉选项——deselect_by_value(value);
通过可见的text选择下拉选项——deselect_by_visible_text(text)；
全部取消——deselect_all()。

返回选项：

返回所有选项——options；
返回第一个选项——first_selected_option;
返回所有选中项——all_selected_options。

判断select选项是否可多选：

is_multiple，返回一个布尔值

选择下拉框的代码：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>select 下拉列表</title>
</head>
<body>
<select id = "S1ID">
<option></option>
<option value ="o1" id = "id1">o1</option>
<option value ="o2" id = "id2">o2</option>
<option value ="o3" id = "id3">o3</option>
</select>
</body>
</html>

from selenium import webdriver
from selenium.webdriver.common.by import By
import os
from time import sleep

file_path = os.getcwd()+os.sep+"myhtml6_2.html"
driver = webdriver.Chrome()
driver.get(file_path)
s1 = Select(driver.find_element(By.ID,"S1ID"))
s1.select_by_index(1)
sleep(2)
s1.select_by_value("o3")
sleep(2)
s1.select_by_visible_text("o2")
sleep(2)
driver.quit()

Note:

index从0开始
value是<option>标签的一个属性值，并不是显示在下拉列表中的值
visible_text是在<option>和<\option>标签对中间的值，是显示在下拉列表中的值

取消下拉框的代码

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>可以多选select 下拉列表</title>
</head>
<body>
<select id = "S1ID" multiple = "multiple">
<option>请选择:</option>
<option value ="o1" id = "id1">o1</option>
<option value ="o2" id = "id2">o2</option>
<option value ="o3" id = "id3">o3</option>
</select>
</body>
</html>

from selenium.webdriver.support.select import Select
from selenium.webdriver.common.by import By
from selenium import webdriver
from time import sleep
import os


file_path = os.getcwd()+os.sep+"myhtml6_3.html"
driver = webdriver.Chrome()
driver.maximize_window()
driver.get(file_path)
ele = Select(driver.find_element(By.ID,"S1ID"))
ele.select_by_index(1)
sleep(2)
ele.deselect_by_index(1)
sleep(2)
ele.select_by_value("o2")
sleep(2)
ele.deselect_by_value("o2")
sleep(2)
ele.select_by_visible_text("o3")
sleep(2)
ele.deselect_by_visible_text("o3")
sleep(2)
ele.select_by_value("o1")
ele.select_by_value("o2")
sleep(2)
ele.deselect_all()
sleep(2)
driver.quit()

返回选项

from selenium.webdriver.common.by import By
from selenium.webdriver.support.select import Select
from selenium import webdriver
from time import sleep
import os

file_path = os.getcwd()+os.sep+"myhtml6_3.html"
drvier = webdriver.Chrome()
drvier.maximize_window()
drvier.get(file_path)
select = Select(drvier.find_element(By.ID,"S1ID"))
sleep(2)
all_options = select.options
print("返回的是：",all_options)
print("")
print("返回数据的数据类型是：{}".format(type(all_options)))
mylist = []
for i in all_options:
    mylist.append(i.text)
print(mylist)
drvier.quit()

输出结果

返回的是： [<selenium.webdriver.remote.webelement.WebElement (session="cace0fdb5748863a770aba459cbbaf42", element="9f7c4c28-e152-4575-be75-1a95538a5f18")>, <selenium.webdriver.remote.webelement.WebElement (session="cace0fdb5748863a770aba459cbbaf42", element="e3b4ae56-6384-4a61-88e2-b37aa233f39b")>, <selenium.webdriver.remote.webelement.WebElement (session="cace0fdb5748863a770aba459cbbaf42", element="64250962-25af-43f4-958a-92db65eaeaaf")>, <selenium.webdriver.remote.webelement.WebElement (session="cace0fdb5748863a770aba459cbbaf42", element="aa86e27b-3b98-453b-b74d-1282069f0591")>]

返回数据的数据类型是：<class 'list'>
['请选择:', 'o1', 'o2', 'o3']

Note:

opions返回的是选项元素，想要获取文字，需要时”.text”

练习需求：循环选择o1,o2,o3

from selenium.webdriver.support.select import Select
from selenium.webdriver.common.by import By
from selenium import webdriver
from time import sleep
import os


file_path = os.getcwd()+os.sep+"myhtml6_3.html"
driver = webdriver.Chrome()
driver.get(file_path)
select = Select(driver.find_element(By.ID,"S1ID"))
all_options = select.options
for i in range(0,len(all_options)):
    if i == 0:
        continue
    select.select_by_index(i)
    sleep(2)
driver.quit()

获取第一个选项的文字：.first_selected_option

from selenium.webdriver.support.select import Select
from selenium.webdriver.common.by import By
from selenium import webdriver
from time import sleep
import os


file_path = os.getcwd()+os.sep+"myhtml6_3.html"
driver = webdriver.Chrome()
driver.get(file_path)
select = Select(driver.find_element(By.ID,"S1ID"))
all_options = select.options
select.select_by_index(2)
select.select_by_index(1)
select.select_by_index(3)
print(select.first_selected_option.text)
driver.quit()

输出结果：o1

Note:我们会发现不管先选中的时哪一个选项，使用first_selected_option方法时返回的都是最上面那个选项。

from selenium.webdriver.support.select import Select
from selenium import webdriver
import os
from time import sleep


file_path = os.getcwd()+os.sep+"myhtml6_3.html"
drvier = webdriver.Chrome()
drvier.get(file_path)
ele = Select(drvier.find_element_by_id("S1ID"))
res = ele.is_multiple
print(res)
drvier.quit()

下面代码中第一个option的text开头有三个空格，第二个option的text中间包含三个空格，第三个option的text中包含了3个’&nbsp’。在HTML中“&nbsp”和空格的区别是，在HTML中没输入一个转义字符’&nbsp’就表示一个空格，输入10个页面就显示10个空格位置。而在HTML代码中不管输入多少个空格，最终页面中显示的空格就只有一个文章来源地址https://www.toymoban.com/news/detail-754289.html
