How to Disable Scrollbars While Keeping Wheel and Arrow Key Scrolling?

Disabling Scrollbars While Preserving Wheel and Arrow Scrolling Functionality

Enhancing user experience by disabling scrollbars while maintaining essential scrolling functionality can be achieved through various techniques. This article explores how to accomplish this using raw JavaScript and jQuery.

Raw JavaScript

To disable scrollbars in raw JavaScript, utilize the overflow: hidden property:

body {
  overflow: hidden;
}

To mimic scrolling with the mouse wheel, bind the wheel event to a function that adjusts the scrollTop value:

document.body.addEventListener("wheel", function (e) {
  document.body.scrollTop += e.deltaY;
});

For arrow key navigation, bind the keydown event to detect key presses and adjust scrollLeft and scrollTop accordingly:

document.body.addEventListener("keydown", function (e) {
  switch (e.keyCode) {
    case 37: // Left arrow
      document.body.scrollLeft -= 10;
      break;
    // Implement other arrow key cases...
  }
});

jQuery

jQuery provides simplified implementations for these concepts:

// Disable scrollbars
$("body").css("overflow", "hidden");

// Mouse wheel scrolling
$("#example").bind("mousewheel", function (ev, delta) {
    $(this).scrollTop($(this).scrollTop() - Math.round(delta));
});

// Arrow key scrolling
$("body").keydown(function (e) {
    switch (e.keyCode) {
        case 37: // Left arrow
            $(this).scrollLeft($(this).scrollLeft() - 10);
            break;
        // Implement other arrow key cases...
    }
});
