如何使用 WebDriverWait() 访问 selenium python 中具有相同 class 名称的下一个元素的值

Question

我正在尝试从该特定站点访问字段 Year 和 Quarter 的值。在 Whosebug 的一位成员的帮助下，我能够实现 year 部分的代码，现在如果我想访问 quarter 部分，那么我该如何访问它。

以下是目前的实施情况。

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

options = webdriver.ChromeOptions()
options.add_argument('--ignore-certificate-error')
options.add_argument('--ignore-ssl-errors')

url = "https://lifeinsurance.adityabirlacapital.com/about-us/public-disclosure"
driver = webdriver.Chrome(executable_path='drivers/chromedriver.exe')

driver.get(url)

WebDriverWait(driver, 20).until(
    EC.element_to_be_clickable((By.CSS_SELECTOR, "div.selectize-input.items.full.has-options.has-items"))
).click()

year_dropdown = WebDriverWait(driver, 20).until(
    EC.visibility_of_all_elements_located(
        (By.CSS_SELECTOR, "div.selectize-dropdown-content div.option")
    )
)

for year in year_dropdown:
    print(year.text)

欢迎任何提示和建议。

Answer 1

您的年度和季度结构相同。一个 selectPublicYear 另一个 selectPublicQuarter class

wait = WebDriverWait(driver, 20)

# Years
year_selector = ".selectize-control.selectPublicYear"
year_option_selector = year_selector + " .option"

wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, year_selector))).click()

wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, year_option_selector)))
years = driver.find_elements(By.CSS_SELECTOR, year_option_selector)
for year in years:
    print(year.text)
years[-1].click()

# Quarters
quarter_selector = ".selectize-control.selectPublicQuarter"
quarter_option_selector = quarter_selector + " .option"

wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, quarter_selector))).click()
# Wait for option element to be clickable.
wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, quarter_option_selector)))
# Get all option elements
quarters = driver.find_elements(By.CSS_SELECTOR, quarter_option_selector)
for quarter in quarters:
    print(quarter.text)
# Select last one
quarters[-1].click()

您可以按值向 select 下拉列表添加方法：

def select_dropdown(name, selector, value):
    print(f'Select "{name}" dropdown, value: "{value}"')

    # Selectors
    selector = ".selectize-control" + selector
    option_selector = selector + " .option"

    wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, selector))).click()

    # Wait for option element to be clickable
    wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, option_selector)))

    # Get all options elements
    option_elements = driver.find_elements(By.CSS_SELECTOR, option_selector)
    # Get text values from options
    options = [opt.text.strip() for opt in option_elements]
    print(f'Available values: {options}')

    # Check if options have value
    if value not in options:
        raise Exception(f'"{name}" dropdown does not have "{value}" value. Available values: {options}')

    option_elements[options.index(value)].click()

调用方式：

select_dropdown(name="Year", selector=".selectPublicYear", value="2020-2021")
select_dropdown(name="Quarter", selector=".selectPublicQuarter", value="Q2: Sep, 2020")

Answer 2

提取文本，例如第 4 季度：2021 年 3 月，所有 <class="option"> 使用 and python you have to induce for visibility_of_all_elements_located() and you can use either of the following ：

使用XPATH:

driver.get('https://lifeinsurance.adityabirlacapital.com/about-us/public-disclosure')
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//label[text()='Quarter']//following::div[@class='selectize-input items full has-options has-items']"))).click()
print([my_elem.text for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH, "//div[@class='selectize-dropdown-content']//div[contains(@class, 'option')]")))])

控制台输出：

['All Quarters', 'Q4: Mar, 2021', 'Q3: Dec, 2020', 'Q2: Sep, 2020', 'Q1: Jun, 2020']

注意：您必须添加以下导入：

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
