如何在不同的标签/窗口中打开选择标签的选项项(下拉菜单)? [英] How to open the option items of a select tag (dropdown) in different tabs/windows?

问题描述

我正在尝试使用Python和Selenium抓取此网站，它要求您从下拉框中选择一个日期，然后单击搜索以查看计划应用程序.

I'm trying to scrape this website using Python and Selenium, it requires you to select a date from drop-down box then click search to view the planning applications.

URL: https://services.wiltshire.gov.uk/PlanningGIS/LLPG/WeeklyList .

我有工作的代码来选择下拉框的第一个索引，然后按搜索.如何为下拉框中的所有日期选项打开多个窗口，或者一个接一个地浏览这些窗口，以便于我进行刮取?

I have the code working to select the first index of the drop-down box and press search. How would I open multiple windows for all the date options in the drop-down box or go through them one by one so I can scrape it?

from selenium import webdriver
from selenium.webdriver.support.ui import Select
from selenium.webdriver.chrome.options import Options


options = Options()
options.add_argument('--headless')
options.add_argument('--disable-gpu')
driver = webdriver.Chrome('/Users/weaabduljamac/Downloads/chromedriver', 
chrome_options=options)

url = 'https://services.wiltshire.gov.uk/PlanningGIS/LLPG/WeeklyList'
driver.get(url)

select = Select(driver.find_element_by_xpath('//*[@id="selWeek"]'))
select.select_by_index(1)

button = driver.find_element_by_id('csbtnSearch')
button.click()

app_numbers = driver.find_element_by_xpath('//*[@id="form1"]/table/tbody/tr[1]/td[1]/a').text
print(app_numbers)

下拉框HTML:

<select class="formitem" id="selWeek" name="selWeek">
   <option selected="selected" value="2018,31">Week commencing Monday 30 July 2018</option>
   <option value="2018,30">Week commencing Monday 23 July 2018</option>
   <option value="2018,29">Week commencing Monday 16 July 2018</option>
   <option value="2018,28">Week commencing Monday 9 July 2018</option>
   <option value="2018,27">Week commencing Monday 2 July 2018</option>
   <option value="2018,26">Week commencing Monday 25 June 2018</option>
   <option value="2018,25">Week commencing Monday 18 June 2018</option>
   <option value="2018,24">Week commencing Monday 11 June 2018</option>
   <option value="2018,23">Week commencing Monday 4 June 2018</option>
   <option value="2018,22">Week commencing Monday 28 May 2018</option>
</select>

推荐答案

根据您的问题，您将无法为不同的下拉选项打开多个窗口，因为 < options> 标签不包含任何 href 属性.他们将始终在同一个浏览器窗口中呈现新页面.

As per your question you won't be able to open multiple windows for different drop-down options as the <options> tags doesn't contains any href attribute. They will always render the new page in the same browser window.

但是从 Dropdown 中选择日期，然后 click() Search 查看日期，您可以使用以下解决方案:

However to select a date from the Dropdown and then click() Search to view the planning applications you can use the following solution:

• 代码块:

• Code Block:

from selenium import webdriver
from selenium.webdriver.support.ui import Select
from selenium.webdriver.chrome.options import Options

options = Options()
options.add_argument('--headless')
options.add_argument("start-maximized")
options.add_argument('disable-infobars')
driver=webdriver.Chrome(chrome_options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
url = 'https://services.wiltshire.gov.uk/PlanningGIS/LLPG/WeeklyList'
driver.get(url)

select = Select(driver.find_element_by_xpath("//select[@class='formitem' and @id='selWeek']"))
list_options = select.options
for item in range(len(list_options)):
    select = Select(driver.find_element_by_xpath("//select[@class='formitem' and @id='selWeek']"))
    select.select_by_index(str(item))
    driver.find_element_by_css_selector("input.formbutton#csbtnSearch").click()
    print(driver.find_element_by_xpath('//*[@id="form1"]/table/tbody/tr[1]/td[1]/a').text)
    driver.get(url)
driver.quit()

控制台输出:

Console Output:

18/06760/FUL
18/07187/LBC
18/06843/FUL
18/06705/FUL
18/06449/FUL
18/05534/FUL
18/06030/DEM
18/05784/FUL
18/05914/LBC
18/05241/FUL

要刮掉所有需要替换的链接:

To scrape all the links you need to replace:

find_element_by_xpath('//*[@id="form1"]/table/tbody/tr[1]/td[1]/a')

具有:

find_elements_by_xpath('//*[@id="form1"]/table/tbody/tr[1]/td[1]/a')
