DOMPointReadOnly.x

The DOMPointReadOnly interface's x property holds the horizontal coordinate, x, for a read-only point in space. This property cannot be changed by JavaScript code in this read-only version of the DOMPoint object.

In general, positive values x mean to the right, and negative values of x means to the left, assuming no transforms have resulted in a reversal.

Syntax

var xPos = DOMPointReadOnly.x;

Value

A double-precision floating-point value indicating the x 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).
