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

var yPos = DOMPointReadOnly.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).
