DOMPointReadOnly.y
The DOMPointReadOnly
interface's
y
property holds the vertical coordinate, y, for a
read-only point in space. If your script needs to be able to change the value
of this property, you should instead use the DOMPoint
object.
In general, positive values of y
mean downward, and negative values of
y
mean upward, assuming no transforms have resulted in a reversal.
Syntax
const yPos = someDOMPointReadOnly.y;
Value
A double-precision floating-point value indicating the y coordinate's value for the
point. This value is unrestricted, meaning that it is allowed to be
infinite or invalid (that is, its value may be NaN
or ±Infinity
).
