Question

I am trying to implement some code on my web page to auto-scroll after loading the page. I used a Javascript function to perform auto-scrolling, and I called my function when the page loads, but the page is still not scrolling smoothly! Is there any way to auto scroll my page smoothly?

Here is my Javascript function:

function pageScroll() {
        window.scrollBy(0,50); // horizontal and vertical scroll increments
        scrolldelay = setTimeout('pageScroll()',100); // scrolls every 100 milliseconds
}

Answer 1

It’s not smooth because you’ve got the scroll incrementing by 50 every 100 milliseconds.

change this and the amount you are scrolling by to a smaller number to have the function run with the illusion of being much more ‘smooth’.

turn down the speed amount to make this faster or slower.

function pageScroll() {
    window.scrollBy(0,1);
    scrolldelay = setTimeout(pageScroll,10);
}

will appear to be much smoother, try it 😉
