Why "AJAX Load" slows down the process
Before Octoparse goes on to executes actions such as Click Item and Click to Paginate, it needs to confirm that the page's fully loaded. And to do this, Octoparse takes page-reloading as the signal for when the web page is ready for the next action in the workflow. For a web page that loads with AJAX, though, the new content is usually updated without reloading; in this case, Octoparse would not get the signal to proceed. As a result, you may get zero or much fewer data extracted than expected.
To work around this issue, we can set up an AJAX Load timeout for the Click Item action. When the timeout is reached, Octopares will proceed to the next action regardless of whether page reloading is detected.
Where to set up the AJAX Load
Click on Click Item or Click to Paginate action
Tick Load with AJAX in Options tab at the bottom of the workflow
Select the AJAX timeout according to how fast your page loads and click Apply to save the setting
Tip: Make sure to set up a timeout long enough for the page or the target information to load. In most cases, Octoparse detects AJAX and sets up the timeout automatically, but you may still need to extend the AJAX timeout for pages that take longer to load. Check out more about AJAX at Handling AJAX
