php - how to remember scroll position of page

Question

I am submitting some data to my database then reloading the same page as the user was just on, I was wondering if there is a way to remember the scroll position the user was just on?

Answer 1

I realized that I had missed the important part of submitting, so, I decided to tweak the code to store the cookie on click event instead of the original way of storing it while scrolling.

Here's a jquery way of doing it:

jsfiddle _{( Just add /show at the end of the url if you want to view it outside the frames )}

Very importantly, you'll need the jquery cookie plugin.

jQuery:

// When document is ready...
$(document).ready(function() {

    // If cookie is set, scroll to the position saved in the cookie.
    if ( $.cookie("scroll") !== null ) {
        $(document).scrollTop( $.cookie("scroll") );
    }

    // When a button is clicked...
    $('#submit').on("click", function() {

        // Set a cookie that holds the scroll position.
        $.cookie("scroll", $(document).scrollTop() );

    });

});

Here's still the code from the original answer:

jsfiddle

jQuery:

// When document is ready...
$(document).ready(function() {

    // If cookie is set, scroll to the position saved in the cookie.
    if ( $.cookie("scroll") !== null ) {
        $(document).scrollTop( $.cookie("scroll") );
    }

    // When scrolling happens....
    $(window).on("scroll", function() {

        // Set a cookie that holds the scroll position.
        $.cookie("scroll", $(document).scrollTop() );

    });

});

@Cody's answer reminded me of something important.

I only made it to check and scroll to the position vertically.
