convert a string into a two-dimensional array in javascript

Question

I'm trying to convert a string like this "10|15|1,hi,0,-1,bye,2" where the first two elements 10|15 mean something different than 1,hi,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(",");

(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]=hi, 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

Is there any way to do that?

Thanks

Solution 1

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

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

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"]]

Solution 2

function getMatrix(input_string) 
{
    var parts = input_string.split('^');
    for (var t=0; t<parts.length; t++)
    {
        var subparts = parts[t].split('*');

        parts[t] = subparts.splice(0,subparts.length);              
    }

    return parts;
}

Solution 3

function getMatrix(input_string) {
    var parts = input_string.split('|');
    var subparts = parts.pop().split(',');
    var partlen = subparts.length / parts.length;
    for (var i=0; i<parts.length; i++) {
        parts[i] = subparts.splice(0,partlen);
    }
    return parts;
}
