TouchList: item() method
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
The item() method returns the Touch
object at the specified index in the TouchList.
Syntax
js
item(index)
Parameters
Return value
The requested Touch object from the TouchList. Returns null if the index is not less than the length of the list.
Examples
This code example illustrates the use of the TouchList interface's
item method and the
length property.
js
const target = document.getElementById("target");
target.addEventListener("touchstart", (ev) => {
// If this touchstart event started on element target,
// set touch to the first item in the targetTouches list;
// otherwise set touch to the first item in the touches list
const touch =
ev.targetTouches.length >= 1
? ev.targetTouches.item(0)
: ev.touches.item(0);
});
