DOMPoint: DOMPoint() constructor

The DOMPoint() constructor creates and returns a new DOMPoint object, given the values for some or all of its properties.

You can also create a DOMPoint by calling the DOMPoint.fromPoint() static function. That function accepts any object with the required parameters, including a DOMPoint or DOMPointReadOnly.


new DOMPoint()
new DOMPoint(x)
new DOMPoint(x, y)
new DOMPoint(x, y, z)
new DOMPoint(x, y, z, w)


x Optional

The x coordinate for the new DOMPoint.

y Optional

The y coordinate for the new DOMPoint.

z Optional

The z coordinate for the new DOMPoint.

w Optional

The perspective value of the new DOMPoint.


This example creates a DOMPoint representing the top-left corner of the current window, then creates a second point based on the first, which is then offset by 100 pixels both vertically and horizontally.

const windTopLeft = new DOMPoint(window.screenX, window.screenY);
const newTopLeft = DOMPoint.fromPoint(windTopLeft);
newTopLeft.x += 100;
newTopLeft.y += 100;
