遍历数组数组 [英] looping through arrays of arrays

问题描述

我有一个数组数组(比如图形)，如何迭代所有数组?

I have an arrays of arrays (some thing like graph), How to iterate all arrays?

var parentArray = [
 [[1,2,3],[4,5,6],[7,8,9]],
 [[10,11,12],[13,14,15],[16,17,18]],
 [[19,20,21],[22,23,24],[26,27,28]]
];

它只是一个示例数组，实际可以包含任意数量的数组，然后是数组.如何打印所有这些数字?它类似于 html 对象 DOM

Its just an example array, actual can contains any number of array and then arrays. How to print all those numbers? Its similar to html objects DOM

推荐答案

这个递归函数应该可以处理任意数量的维度:

This recursive function should do the trick with any number of dimensions:

var printArray = function(arr) {
    if ( typeof(arr) == "object") {
        for (var i = 0; i < arr.length; i++) {
            printArray(arr[i]);
        }
    }
    else document.write(arr);
}

printArray(parentArray);
