python - 如何在 python 中使用 Selenium 包单击多个复选框和下拉菜单？

Question

我正在尝试选择此网站中未选中的复选框:https://dataunodc.un.org/GSH_app ，在“国家数据”中。此外，我想从下拉菜单中选择“100”(“显示...条目”)。

我正在使用 selenium 和 python。你能告诉我怎么做吗？

这是与复选框选择相对应的 HTML 代码的一部分:

                    <label class="checkbox-inline">
                      <input type="checkbox" name="YearVar" value="1990" checked="checked">
                      <span>1990</span>
                    </label>
                    <label class="checkbox-inline">
                      <input type="checkbox" name="YearVar" value="1991">
                      <span>1991</span>
                    </label>
                    <label class="checkbox-inline">
                      <input type="checkbox" name="YearVar" value="1992"

这一个对应于下拉菜单:

 name="DataTables_Table_0_length" aria-
controls="DataTables_Table_0" class=""><option
 value="10">10</option><option
 value="25">25</option><option
 value="50">50</option><option 
 value="100">100</option></select> entries</label>

要获取所有未选中的复选框，然后单击这些复选框。

引入 WebDriverWait() 和 visibility_of_all_elements_ located() 以及后面的 XPATH 选项。然后迭代元素并单击每个元素。

#Get all checkbox which are not selected.
allchekbox=WebDriverWait(driver,10).until(EC.visibility_of_all_elements_located((By.XPATH,"//input[@name='YearVar' and not(@checked='checked')]")))

for item in allchekbox:
    item.click()

In order to select value for dropdown use selenium select class.

引发 WebDriverWait() 和 visibility_of_element_ located() 以及任一 Xpath 选项。

XPATH 1:

 # Select Item from dropdown
element = WebDriverWait(driver, 10).until(EC.visibility_of_element_located((By.XPATH, "//select[starts-with(@name,'DataTables_Table_')]")))
select = Select(element)
select.select_by_value("100")

或者

XPATH 2:

element = WebDriverWait(driver, 10).until(EC.visibility_of_element_located((By.XPATH, "//label[normalize-space(text())='Show']/select")))
select = Select(element)
select.select_by_value("100")

这是完整的代码:

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.select import Select
import time
driver = webdriver.Chrome()
driver.get("https://dataunodc.un.org/GSH_app")
driver.maximize_window()

#Switch the iframe in order to access the link
WebDriverWait(driver,15).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"//iframe[@src='https://unodc.shinyapps.io/GSH_App/']")))
#Click on National Data link
WebDriverWait(driver,5).until(EC.element_to_be_clickable((By.XPATH,'//ul[@class="nav navbar-nav"]//a[text()="National Data"]'))).click()

#Get all checkbox which are not selected.
allchekbox=WebDriverWait(driver,10).until(EC.visibility_of_all_elements_located((By.XPATH,"//input[@name='YearVar' and not(@checked='checked')]")))

#iterate and click each checkbox
for item in allchekbox:
    item.click()

#To avoid StaleElementReferenceException add time.sleep()
time.sleep(2)
# Select Item from dropdown
element = WebDriverWait(driver, 10).until(EC.visibility_of_element_located((By.XPATH, "//select[starts-with(@name,'DataTables_Table_')]")))
select = Select(element)
select.select_by_value("100")
