Latest Inquiries - Data Extraction Software

techdata auto scrolling browsers

Submitted: 1/5/2016

HI,

You already addressed this issue, but I can't seem to find the log file describing how you created a group and scroll link object to cause the product list page to scroll more and show more products before grabbing them.

I was running the VWR project you helped fix and it sort of works.  But I need to change it a little so it will scroll more, like 5 to 10 pages so I can get more than 30 products. 


tried to review your scroll element and check its settings but I don't see how it works.  It just looks like a link that selects the entire page with product list.  Can you explain where I change the setting to make it scroll more times before data extraction on the products begins?


thanks


attached is the project file.

Please check the attached new project.

Actually, you don't have to make any new configuration for templates, instead, I only move some templates to certain place such as the 'product list' template should be put underneath 'group' template, so after 'group' template and its sub-template 'scroll' , page navigation template loads more products , then 'product list' template starts to collect through all products.

When you edit 'scroll' link template, 'windowscroll' action has been added in Advanced tab > Action section (at righ hand side), and setting to 'Repeated AJAX calls ' = true, this will ensure that page can be scroll down automatically , moreover, you should be noted that 'Repeated AJAX calls max. count' = 0 by default, that means it will auto-matically scroll page down until there is a failure (no more pages), but sometimes, if there is too much pages being loaded then it will raise a 'out of memory ' issue, in case you should set a fixed max. count, also, you should set a fixed page count with page navigation template for the limitation of pages.

You still can refer to the below topic link for understanding:
