核心代码:
java
//js
function handle(array) {
var result = [];
for (let i = 0; i < array[0].length; i++) {
var item = [];
for (let j = 0; j < array.length; j++) {
item.push(array[j][i])
}
result.push(item);
}
return result;
}
运行代码:
javascript
let arr = [
['a1', 'b1', 'c1'],
['a2', 'b2', 'c2'],
['a3', 'b3', 'c3'],
];
function handle(array) {
var result = [];
for (let i = 0; i < array[0].length; i++) {
var item = [];
for (let j = 0; j < array.length; j++) {
item.push(array[j][i]);
}
result.push(item);
}
return result;
}
console.log("数组>>>", arr);
console.log("按列循环二维数组>>>", handle(arr));
