python 中的 selenium。 试图 select 元素

Question

UPDATE: I found out what caused the issue in my original post, but don't know how to solve. Here is some more of my code. I first did a search, after which my page in firefox jumped to www.flickr.com/searc/?text=volleybal. but apparently my browser object still sits on www.flickr.com. How can I update it?

from selenium import webdriver
browser = webdriver.Firefox()
browser.get('https://www.flickr.com')
s = browser.find_element_by_id('search-field')
s.send_keys('volleyball')
s.submit()
s = browser.find_element_by_class_name("style-button")
#s = browser.find_element_by_xpath("//li[@data-style-value = 'minimalism']")
s.click()

---

original post:

I'm experimenting with selenium, and I want to select the following element:

<li class="style-button minimalist" data-style-value="minimalism" data-tooltip-title="Minimalist" tabindex="0" role="button" aria-label="Minimalist">

I have tried the following, but none of them work:

s = browser.find_element_by_class_name("style-button minimalist")

s = browser.find_element_by_class_name("style-button.minimalist")

s = browser.find_element_by_css_selector("li.style-button.minimalist")

s = browser.find_element_by_css_selector(".style-button.minimalist")

How can I select this element?

Answer 1

You could try an XPath here:

s = browser.find_element_by_xpath("//li[contains(@class, 'style-button')]")

Hope this helps a bit.

Answer 2

Solved. Added browser.refresh() after s.submit()

Answer 3

The best option is to use absolute xpath . It for that button will be:

/html[1]/body[1]/div[1]/div[1]/div[3]/div[1]/div[1]/div[1]/div[2]/ul[1]/li[3]

Moreover, I found that sometimes the page is not loaded and the selenium searches for the element, which results in error. You can wait for the element to appear. You can find more information here .

With the combination of these, your code will be:

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


browser = webdriver.Firefox()
browser.get('https://www.flickr.com/')
s = browser.find_element_by_id('search-field')
s.send_keys('volleyball')
s.submit()

s = WebDriverWait(browser, 10).until(EC.presence_of_element_located((By.XPATH, "/html[1]/body[1]/div[1]/div[1]/div[3]/div[1]/div[1]/div[1]/div[2]/ul[1]/li[3]")))
s.click()

Answer 4

your code works perfectly

try download last version of geckodriver for your using OS and set your executable_path

it should like this

browser = webdriver.Firefox(executable_path="./geckodriver")

and try again run your improved code
