Title: When invoking new page by scroll down from infinite_scroll
Post by: kjvjung on September 05, 2017, 07:14:49 pm

Hello.

New page call by scroll down in infinite_scroll: What do you know?

I will explain in detail.

             postData: function () {
debugger; // What can I tell if it was called by scroll down?
                 return {
                     pq_curpage: pqIS.requestPage,
                     pq_rpp: pqIS.rpp
                 };
             },

I see 100 lines at first, and when I scroll down, I see 100 lines again.
What are the characteristics of this time? How do I know from the debugger above?
When you scroll down, postData is called. What variables can I see at this time?

For example, instead of debugger, console.log (....)

That's right, postData is called whenever more rows are requested from remote server.

beforeTableView -> if more rows are required -> this.refreshDataAndView(); -> postData()
