JS 数组按指定长度切割，返回一个新的数组集合，比如按照3的倍数切割，返回结果为每三个一组
<html>
<script>
function arraySlice(array, sliceNum) {
var newArray = [];
let viod = 0;//数组初始量
for (let i = 0; i < array.length; i++) {
if (i % sliceNum == 0 && i != 0) {
newArray.push(array.slice(viod, i));
viod = i;
}
if (i + 1 == array.length) {
newArray.push(array.slice(viod, i + 1));
}
}
return newArray;
}
var array = [
{ name: "1", },
{ name: "2", },
{ name: "3", },
{ name: "4", },
{ name: "5", },
{ name: "6", },
{ name: "7", },
{ name: "8", },
{ name: "9", },
{ name: "10", },
{ name: "9", },
{ name: "10", },
]
var newArray = arraySlice(array, 3);
console.log(newArray);
</script>
