Feeling trapped in designing workflows on your own for a long time? Cannot manage to get the data by yourself? Here's a new solution for beginners: Auto-detect webpage.
The auto-detect function is one of the newest innovations of Octoparse version 8. With the function, users can easily start their work by simply clicking a single button. The function has been successfully proved to handle webpages of different designs with listings, tables, infinite scrolls, load more buttons, etc. Now it's the time to introduce this most useful and powerful function to our valuable users.
How to utilize the function
1. Enter the URL on the home page
Enter the example URL "https://www.ebay.com/b/Laptops-Netbooks/175672/bn_1648276" into the search box at the center of the home screen. Click "Start" to create a new task with Advanced Mode.
2. Start the auto-detection
The detection will start after you click on the "Auto-detect web page data" and we can just wait for it to complete.

There will be options like "extract list", "paginate", "page scroll" listed on the "Tips" panel,

- Click on a "Load More" button- If there is a load more button existing on the webpage, then you can choose this option, select the load more button on the page, and set click times to let the scraper automatically click the button to load more data for scraping.
- Click on link(s) to scrape the linked pages- If you want to click on the links detected and extract more information from the detail pages, choose this option and select a link you want to click on.
To confirm if the links are the ones you'd like to click through, click "Check" to have the links highlighted on the web page.
