Cant select a <li element from a dropdon menu using the Selenium

问题

I've opened the menu using the provided code:

browser = webdriver.Chrome()

url="https://www.daraz.pk/products/candy-by-haier-1-ton-heat-cool-dc-inverter-white-colour-ac-csu-12hp10-years-brand-warranty-i276904502-s1494701276.html?spm=a2a0e.seller.list.2.18b049aahnIdR0&amp;mp=1"
browser.get(url)
browser.maximize_window()

browser.find_element(By.CSS_SELECTOR,"#module_product_review > div > div > div:nth-child(2) > div > div:nth-child(3)").click()

However, when trying to click an option from the dropdown menu with this code:

browser.find_element(By.CSS_SELECTOR,'body > div:nth-child(49) > div > div > ul > li:nth-child(2)').click()

You're encountering the error:

Message: no such element: Unable to locate element: {"method":"css selector","selector":"body > div:nth-child(49) > div > div"}

You've also tried various solutions from this question, but none seem to be working. You've tried using XPATH, CSS selector, LINK_NAME, and PARTIAL_LINK_NAME without success. Any help would be greatly appreciated.

browser.find_element(By.CSS_SELECTOR,&quot;#module_product_review &gt; div &gt; div &gt; div:nth-child(2) &gt; div &gt; div:nth-child(3)&quot;).click()


however when i try to click an option from the dropdown menu using the following code

browser.find_element(By.CSS_SELECTOR,&#39;body &gt; div:nth-child(49) &gt; div &gt; div &gt; ul &gt; li:nth-child(2)&#39;).click()

Message: no such element: Unable to locate element: {"method":"css selector","selector":"body > div:nth-child(49) > div > div"}

This is the HTML for the drop down-(Sorry, I'm new to coding and don't know how to copy the html and paste it here, attaching an image instead

Ive tried multiple solutions including the solution in this question

https://stackoverflow.com/questions/40097838/how-to-click-on-the-list-of-the-li-elements-in-an-ul-elements-with-selenium

Nothing seems top be working and i cant figure why it wont detect an element on either XPATH or CSS detector. I've even tried using LINK_NAME and PARTIAL_LINK_NAME and i run into the same issue. Any help will be greatly appreciated.

你需要使用"WebDriverWait"来等待页面渲染完成。

尝试以下代码:

import time
import requests
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.wait import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

browser = webdriver.Chrome()

url = "https://www.daraz.pk/products/candy-by-haier-1-ton-heat-cool-dc-inverter-white-colour-ac-csu-12hp10-years-brand-warranty-i276904502-s1494701276.html?spm=a2a0e.seller.list.2.18b049aahnIdR0&amp;mp=1"
browser.get(url)
browser.maximize_window()

xpath = r'//*[@id="module_product_review"]/div/div/div[2]/div/div[2]'
WebDriverWait(browser, 20).until(EC.presence_of_element_located((By.XPATH, xpath))).click()

time.sleep(10)

You have to use "WebDriverWait" to wait until the page is being rendered

try this code :

import time

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

browser = webdriver.Chrome()


url=&quot;https://www.daraz.pk/products/candy-by-haier-1-ton-heat-cool-dc-inverter-white-colour-ac-csu-12hp10-years-brand-warranty-i276904502-s1494701276.html?spm=a2a0e.seller.list.2.18b049aahnIdR0&amp;mp=1&quot;
browser.get(url)
browser.maximize_window()


xpath= r&#39;//*[@id=&quot;module_product_review&quot;]/div/div/div[2]/div/div[2]&#39;
WebDriverWait(browser, 20).until(EC.presence_of_element_located((By.XPATH, xpath))).click()

time.sleep(10)
