Splash is a javascript rendering service. Install Splash following the instruction listed for our corresponding OS. This is a plus over other solutions until this point, as it utilizes an OS-independent platform. Solution 1: This is a very nice tutorial on how to use Scrapy to crawl javascript generated content and we are going to follow just that.ĭocker installed in our machine. Therefore we need to render the javascript content before we crawl the page.Īs selenium is already mentioned many times in this thread (and how slow it gets sometimes was mentioned also), I will list two other possible solutions.
When we fetch an HTML page, we fetch the initial, unmodified by javascript, DOM. We are not getting the correct results because any javascript generated content needs to be rendered on the DOM. #Scraping with JS support: import dryscrape You can also use Python library dryscrape to scrape javascript driven websites. P_element = driver.find_element_by_id(id_='intro-text') #Scraping with JS support: from selenium import webdriver #Scraping without JS support: import requests Without javascript it says: No javascript support and with javascript: Yay! Supports javascript
( link): ĭocument.getElementById('intro-text').innerHTML = 'Yay! Supports javascript' To give an example, I created a sample page with following HTML code. Once you have installed Phantom JS, make sure the phantomjs binary is available in the current path: phantomjs -version
I have found using Selenium's python library with Phantom JS as a web driver fast enough and easy to get the work done. The old answer is still at the end.ĭryscape isn't maintained anymore and the library dryscape developers recommend is Python 2 only. EDIT Sept 2021: phantomjs isn't maintained any more, eitherĮDIT 30/Dec/2017: This answer appears in top results of Google searches, so I decided to update it.
