如何使用 selenium python 抓取多级下拉列表 [依赖选择]

Question

我想从多级选择相关下拉菜单中提取一些数据，谁能告诉我如何使用 selenium 选择和单击项目，以便子下拉菜单可以自动更新！

您可以访问源以供参考或运行代码以查看单击后的输出它永远不会选择项目。

我在这里写了几个代码就是其中之一！

from selenium import webdriver
from selenium.webdriver.support.ui import Select
from selenium.webdriver.common.by import By
import csv
import time

//#from selenium.webdriver.support import Select 

print ("opening chorome....")  
driver = webdriver.Chrome()
driver.get('https://www.wheelmax.com/')
time.sleep(10)

csvData = ['Year', 'Make', 'Model', 'Body', 'Submodel', 'Size']

Yindex = Mkindex = Mdindex = Bindex = Smindex = Sindex = 0
print ("waiting for program to set variables....")
time.sleep(10)

print ("initializing and setting variables....")

Year = Select(driver.find_element_by_id("icm-years-select"))
for year in driver.find_elements(By.XPATH, '//*[@id="icm-years-select"]'):
    Year.select_by_index(++Yindex)
    year.click()
    time.sleep(1)
    Make = Select(driver.find_element_by_id("icm-makes-select"))
    for make in driver.find_elements(By.XPATH, '//*[@id="icm-makes-select"]'):
        Make.select_by_index(++Mkindex)
        make.click()
        time.sleep(1)
        Model = Select(driver.find_element_by_id("icm-models-select"))
        for model in driver.find_elements(By.XPATH, '//*[@id="icm-models-select"]'):
            Model.select_by_index(++Mdindex)
            model.click()
            time.sleep(1)
            Body = Select(driver.find_element_by_id("icm-drivebodies-select"))
            for body in driver.find_elements(By.XPATH, '//*[@id="icm-drivebodies-select"]'):
                Body.select_by_index(++Bindex)
                body.click()
                time.sleep(1)
                Submodel = Select(driver.find_element_by_id("icm-submodels-select"))
                for subm in driver.find_elements(By.XPATH, '//*[@id="icm-submodels-select"]'):
                    Submodel.select_by_index(++Smindex)
                    subm.click()
                    time.sleep(1)
                    Size = Select(driver.find_element_by_id("icm-sizes-select"))
                    for size in driver.find_elements(By.XPATH, '//*[@id="icm-sizes-select"]'):
                        Size.select_by_index(++Sindex)
                        csvData.append([year.text, make.text, model.text, body.text, subm.text, size.text])

尝试这个：

选择多级依赖下拉菜单选项

selectYear = Select(driver.find_element_by_id("icm-years-select"))

for yearOption in selectYear.options:
    yearText = yearOption.text
    selectYear.select_by_visible_text(yearText)
    time.sleep(1)

    selectMakes = Select(driver.find_element_by_id("icm-makes-select"))

    for makesOption in selectMakes.options:
        makesText = makesOption.text
        selectMakes.select_by_visible_text(makesText)
        time.sleep(1)
        selectModel = Select(driver.find_element_by_id("icm-models-select"))

        for modelOption in selectModel.options:
            modelText = modelOption.text
            selectModel.select_by_visible_text(modelText)
