在創軟小程序開發電商項目時，遇到商品sku組合算法，本以為sku挺簡單，但還是有一點難度。創軟小程序開發團隊將電商項目開發中的sku組合算法js版本整理如下，供參考學習。
<html>
<head>
<script type="text/javascript">
function f_sku_chk(list, count, array, ind, start, indexs) {
start++;
if (start > count - 1) {
return;
}
if (start == 0) {
indexs = new Array(array.length);
}
for (indexs[start] = 0; indexs[start] < array[start].length; indexs[start]++) {
f_sku_chk(list, count, array, 0, start, indexs);
if (start == count - 1) {
var temp = new Array(count);
for (var i = count - 1; i >= 0; i--) {
temp[start - i] = array[start - i][indexs[start - i]];
}
list.push(temp);
}
}
}
var temp = [
["A", "B", "C"],
["1", "2"],
["X1", "X2", "X3"]
];
var list = [];
f_sku_chk(list, temp.length, temp, 0, -1);
for (var i = 0; i < list.length; i++) {
console.log(list[i]);
}
</script>
