ScrollToOptions

The ScrollToOptions dictionary of the CSSOM View spec contains properties specifying where an element should be scrolled to, and whether the scrolling should be smooth.

A ScrollToOptions dictionary can be provided as a parameter for the following methods:

Properties

ScrollToOptions.top
Specifies the number of pixels along the Y axis to scroll the window or element.
ScrollToOptions.left
Specifies the number of pixels along the X axis to scroll the window or element.
ScrollToOptions.behavior
Specifies whether the scrolling should animate smoothly, or happen instantly in a single jump. This is actually defined on the ScrollOptions dictionary, which is implemented by ScrollToOptions.

Examples

In our scrolltooptions example (see it live) we include a form that allows the user to enter three values — two numbers representing the left and top properties (i.e. the positions to scroll to along the X and Y axes), and a checkbox indicating whether they want smooth scrolling enabled or not.

When the form is submitted, an event handler is run that puts the entered values into a ScrollToOptions dictionary, and then invokes the Window.ScrollTo() method, passing the dictionary as a parameter:

form.addEventListener('submit', (e) => {
  e.preventDefault();
  var scrollOptions = {
    left: leftInput.value,
    top: topInput.value,
    behavior: scrollInput.checked ? 'smooth' : 'auto'
  }

  window.scrollTo(scrollOptions);
});
