Prevent the page from scrolling to an element when it is focused
An element can be focused by either using the
autofocus="true" attribute or calling the
element.focus() method. In both cases, the browser will automatically scroll the element into the viewport.
It is not a problem in most cases but I have seen a few scenarios where we would like to avoid the behaviour.
For example, focusing on a text field inside a modal automatically might scroll the page to the top.
There are two solutions to prevent this behaviour.
Use the preventScroll option
We can pass the
preventScroll option to the
focus() method as following:
Scroll to the previous point
This approach works in all browsers. We store the mouse location before calling the
focus() method, and then scroll to that location later:
const x = window.scrollX;
const y = window.scrollY;
