PointerEvent: width property
The width
read-only property of the
PointerEvent
interface represents the width of the pointer's contact
geometry along the x-axis, measured in CSS pixels. Depending on the source of the
pointer device (such as a finger), for a given pointer, each event may produce a
different value.
If the input hardware cannot report the contact geometry to the browser, the width
defaults to 1
.
Value
The width of the event's contact area (in CSS pixels).
Examples
This example illustrates using the PointerEvent
interface's
width
and
height
properties to calculate the contact area.
js
target.addEventListener(
"pointerdown",
(ev) => {
// Calculate the contact area
const area = ev.width * ev.height;
},
false,
);
