将一个字符串转换在JavaScript中的二维数组 [英] convert a string into a two-dimensional array in javascript

问题描述

我想这样的字符串转换10 | 15 | 1，喜，0，-1，再见，2，其中前两个元素 10 | 15 意味着什么比 1，喜0，-1，再见，2 。我想他们相互分离。完成了一个天真的方法是：

I'm trying to convert a string like this "10|15|1,0,-1,bye,2" where the first two elements 10|15 mean something different than 1,0,-1,bye,2. I would like to separate them from each other. A naive way to accomplish that would be:

value = string.split("|");
var first = value[0];
var second = value[1];
var tobearray = value[2];
array = tobearray.split(",");

（当然，如果你知道一种更好的方式来做到这一点，我会很高兴知道）。
然而，阵列是包含数组数组[0] = 1，阵列[1] =喜阵[2] = 0，数组[ 3] = - 1 等，但是，我想获得的二维阵列，例如

(Of course, if you know a way to do this in a better way, I'd be glad to know). However, array is an array which contains array[0]=1, array[1]= array[2]=0, array[3]=-1, etc. However, I want to obtain a two dimensional array such as

array[0][0]=1, array[0][1]=hi, array[0][2]=0
array[1][0]=-1, array[1][1]=bye, array[1][2]=2

有没有办法做到这一点？

Is there any way to do that?

推荐答案

前两个元素（ 10 | 15 ）可以预先提取。之后，留给你的：

The first two elements (10|15) can be extracted beforehand. After that you're left with:

var a = "1,hi,0,-1,bye,2";

我们的拼接的，直到我们一无所有：

Let's splice until we're left with nothing:

var result = [];

a = a.split(','); 

while(a[0]) {
    result.push(a.splice(0,3));
}

result; // => [["1","hi","0"],["-1","bye","2"]]
