not able to lazy load in phantomjs

问题

I'm trying to scrape some information from the link (http://www.myntra.com/women-sarees?nav_id=606) that involves lazy loading. Below is my code snippet for this:

window.setInterval(function() {
    //var count returns the visibility of the div that checks for lazyloading
    if((count == 'none')) { // more products to be loaded
        page.evaluate(function() {
            // Scrolls to the bottom of page
            window.document.body.scrollTop = document.body.scrollHeight;
        });
        page.render('myn'+k+'.png');
    }
    else { // Found
        //Do what you want
        //console.log('len123');
}, 5000); // Number o ms to wait between scrolls

But I'm getting only first 6 rows loaded. I don't understand where am I going wrong.
