点
is an interface, which existed only briefly in the
CSS Transforms Level 1
specification, which represents a point in 2-dimensional space. It is non-standard, not broadly compatible, and should not be used.
Although it is not directly related to this defunct interface, you are probably looking for
DOMPoint
, which is part of the
Geometry Interfaces Module Level 1
规范。
x
A floating-point value specifying the point's position with respect to the X (horizontal) axis.
y
A floating-point value specifying the point's position with respect to the Y (vertical) axis.
This class was specified in the defunct 20 March 2009 Working Draft of CSS 2D Transforms Module Level 3 . It is not present in the current working draft of the CSS Transforms Level 1 规范。
