Selenium chromedriver 获取元素并填写表单

Question

我期待在this website 填写表格。在第一步中，我无法找到与“州名：”的第一个下拉菜单对应的元素。任何帮助将不胜感激。 到目前为止，这是我尝试过的：

import os
from selenium import webdriver
driver_path = r'pathtochromedriver\chromedriver.exe'
driver = webdriver.Chrome(driver_path)
driver.get('https://app.cpcbccr.com/ccr/#/caaqm-dashboard-all/caaqm-landing/data')
elem = driver.find_element_by_name('State Name :')

Answer 1

您以错误的方式获取此元素。Selenium 找不到它。

如果您只想获取第一个下拉列表中的元素，请尝试以下代码：

import time
from selenium import webdriver
import os

driver_path = r'pathtochromedriver\chromedriver.exe'
driver = webdriver.Chrome(driver_path)
driver.get('https://app.cpcbccr.com/ccr/#/caaqm-dashboard-all/caaqm-landing/data')
time.sleep(8) # sleep some time for waiting(It depends on your internet speed).You could also try WebDriverWait or implicitly_wait

elem = driver.find_elements_by_class_name('toggle')[0] # get the first dropdown button
elem.click() # click it.
 
dropdown = driver.find_element_by_css_selector('.options')
for state in dropdown.find_elements_by_css_selector('li'):
    print(state.text) # get the text in dropdown menu

这给了我：

Andhra Pradesh
Assam
Bihar
Chandigarh
Delhi
Gujarat
Haryana
Jharkhand
Karnataka
Kerala
Madhya Pradesh
Maharashtra
Meghalaya
Mizoram
Nagaland
Odisha
Punjab
Rajasthan
Tamil Nadu
Telangana
Uttar Pradesh
West Bengal
