jquery - Retain scrollbar position even after reloading using javascript

Question

I have requirement where if I click on a checkbox the value gets submitted and hence the page gets reloaded. Now, to click another checkbox, i need to scroll down again which is not a better idea. So, now I want to retain my scrollbar position even after page gets reloaded. Is there any method in javascript to do that? I have tried the below code, but there was no luck.

<input type="checkbox" onclick="myFunction()"/> One <br/>

function myFunction() {
         document.body.scrollTop = 500px;
        }

I also browsed many websites but nothing worked for me. Please help me with this issue.

Thanks.

You can use session storage to store the position then get back to the position when the page is reloaded, like this:

$(window).scroll(function() {
  sessionStorage.scrollTop = $(this).scrollTop();
});

$(document).ready(function() {
  if (sessionStorage.scrollTop != "undefined") {
    $(window).scrollTop(sessionStorage.scrollTop);
  }
});

Here is the JSFiddle demo
