Is it possible to write a bookmarklet that repeatedly jumps to the end of page in the background?

I want to scroll down "all the way" on Facebook. Currently I have to do it manually by sending End-of-page multiple times. I would like to do that automatically and in the background (i.e. I can continue browse in another window or tab while my Facebook tab scrolls down).

this might help

you can use this code to scroll to the bottom of the page

window.scrollTo(0, document.body.scrollHeight);

if you wrap it in a setInterval, you can make it repeat this might work

javascript:setInterval(window.scrollTo, 1000, 0, document.body.scrollHeight)

  • That looked very promising, but when I make a bookmarklet of it (in Firefox) and click it, it replaces the content of the page with a number. can you fix that? If so, I will mark it at the accepted answer. It would also be great if it allowed me to set the number of repetitions (e.g., 10 - that is, "end of page" 10 times and wait 2 seconds after each "end of page" to allow for loading more content) in the bookmarklet. – d-b Nov 07 '22 at 22:23
  • I'm not sure what the issue is but if Firefox is loading a number there is a fix for it. you can fix the number problem by just adding something like Console.log(":)") to the end of it. if Firefox is causing the issue than I cant solve it, I don't have Firefox – CoastStarlight Nov 08 '22 at 14:05
  • What is the exact syntax for that? – d-b Nov 08 '22 at 14:33

    `javascript:setInterval(window.scrollTo, 1000, 0, document.body.scrollHeight);Console.log(":)")` – CoastStarlight Nov 08 '22 at 20:46
  • That worked! And how do you make it repeat 10 times with 1 second delay between repetitions? – d-b Nov 08 '22 at 21:09
  • you can put it in a self calling funtion like so `javascript:scrollnum = 0;function scroll10() {window.scrollTo(0, document.body.scrollHeight);scrollnum++;if(scrollnum < 10) {setTimeout(scroll10, 1000)}};scroll10();Console.log(":)");` hopefully that should work – CoastStarlight Nov 08 '22 at 21:51
