DOMRectReadOnly

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

Constructor

DOMRectReadOnly()

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).
