The top
property of the ScrollToOptions
dictionary specifies the number of pixels along the Y axis to scroll the window or element.
Syntax
top: double
Value
A double.
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); });
