DOMRectReadOnly

Draft
This page is not complete.

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The DOMRectReadOnly interface specifies the standard properties used by DOMRect to define a rectangle.

Constructor

DOMRectReadOnly()
Defined to create a new DOMRectReadOnly object, but note that this constructor cannot be called by 3rd party JavaScript: doing so returns an "Illegal constructor" typeError.

Properties

DOMRectReadOnly.x Read only
The x coordinate of the DOMRect's origin.
DOMRectReadOnly.y Read only
The y coordinate of the DOMRect's origin.
DOMRectReadOnly.width Read only
The width of the DOMRect.
DOMRectReadOnly.height Read only
The height of the DOMRect.
DOMRectReadOnly.top Read only
Returns the top coordinate value of the DOMRect (usually the same as y.)
DOMRectReadOnly.right Read only
Returns the right coordinate value of the DOMRect (usually the same as x + width).
DOMRectReadOnly.bottom Read only
Returns the bottom coordinate value of the DOMRect (usually the same as y + height).
DOMRectReadOnly.left Read only
Returns the left coordinate value of the DOMRect (usually the same as x).

Methods

DOMRectReadOnly.fromRect()
Creates a new DOMRect object with a given location and dimensions.
