Use of scrollPosition to scroll to bottom

[Monish Gupta]

Hi all,

I have a webpage with infinite scrolling. For this page, I need to scroll to bottom of the page. Following is the snippet of code I am trying to run:

    page.open(webPageUrl, function (status) {

        if (status !== 'success') {

            console.log('FAIL to load the address. ');

        }

        setTimeout(function(){

            page.evaluate(function() {

              // Scrolls to the bottom of page

              window.document.body.scrollTop = document.body.scrollHeight;

            });

        }, 10000);

    });

Question

1. Is the above approach correct and should work in PhantomJS?

2. Is there a way to verify if the scroll is actually happening? I tried following to check this:

• I tried page.render before and after, both screenshots are same with no scrolling.
  
• I tried getting values of body.scrollHeight before and after the above code snippet. Both giving value of 300. Seems like page.viewportSize is also not working for me.

 Any pointers would be a great help.

Thanks in advance!
