句法

arr.values()
					

返回值

A new Array Iterator 对象。

范例

Iteration using for...of loop

var arr = new Uint8Array([10, 20, 30, 40, 50]);
var eArray = arr.values();
// your browser must support for..of loop
// and let-scoped variables in for loops
for (let n of eArray) {
  console.log(n);
}
					

Alternative iteration

var arr = new Uint8Array([10, 20, 30, 40, 50]);
var eArr = arr.values();
console.log(eArr.next().value); // 10
console.log(eArr.next().value); // 20
console.log(eArr.next().value); // 30
console.log(eArr.next().value); // 40
console.log(eArr.next().value); // 50
