Navigating through JavaScript links in Selenium (Scrapy) and returning to the initial page: A step-by-step guide

Having some difficulties with pages that have javascript links embedded in them. This issue arises when the page contains a list of cities with javascript in their links. Each link needs to be navigated individually, scraping information and then returning to the list to proceed to the next city for scraping.

The problem occurs after clicking on the javascript links using selenium web driver. Upon navigating back to the list page, the response is lost and an error like the following is displayed:

selenium.common.exceptions.NoSuchElementException: Message: u'Unable to locate element: {"method":"id","selector":"some_id"}'

Any alternatives or workarounds for this issue?

Answer №1

Typically, JavaScript is primarily used for handling ajax requests. To replicate its functionality in Scrapy, it is important to comprehend the actions performed by JavaScript and recreate them without relying on Selenium. You can achieve this by utilizing Chrome Developer tools or Firefox Firebug. If there is a necessity for JavaScript-defined variables, one possible solution is to utilize a JavaScript engine like v8 (within a wrapper such as pyV8).

Is there a specific scenario or example that we can assist you with?
