如何使用 selenium 在 python 中执行 JavaScript 代码？

Question

I try to extract some info through selenium using these:

from selenium import webdriver  # $ pip install selenium
from selenium.webdriver.chrome.options import Options

path = 'C:/Users/Жираслан/Downloads/chromedriver_win32 (1)/chromedriver.exe'
wd = webdriver.Chrome(executable_path=path)
result = wd.find_element_by_class_name('wrapper__top_3UDaE')

when the code in the web-page's elements are:

<div class="wrapper__top_3UDaE">
    <h3>Лидерборд</h3>
    <span class="wrapper__description_nfMmy">...</span>
</div>

and after

result = wd.find_element_by_class_name('wrapper__top_3UDaE')
result

I get the next error:

Message: no such element: Unable to locate element: {"method":"css selector","selector":".wrapper__top_3UDaE"}
  (Session info: chrome=86.0.4240.75)

Please, give me a hint on how to implement this correctly. Thanks.

Answer 1

In your example, you give us the HTML code for a div

<div class="wrapper__top_3UDaE">
    <h3>Лидерборд</h3>
    <span class="wrapper__description_nfMmy">...</span>
</div>

To get your element, you will need the following imports

from selenium import webdriver
from selenium.webdriver.common.by import By

Then, you can use this xpath

//div[@class='wrapper__top_3UDaE']

and you should be able to get your element

wd = webdriver.Chrome(executable_path=path)
result = wd.find_element(By.XPATH, "//div[@class='wrapper__top_3UDaE']")

If your div is a button, you can click on your element

wd = webdriver.Chrome(executable_path=path)
result = wd.find_element(By.XPATH, "//div[@class='wrapper__top_3UDaE']")
result.click()
