Question

I have a string value like:

1,2,3;4,5,6;7,8,9;a,b,c;d,e,f;g,h,i

I need to convert it into array in JavaScript like

1 2 3

4 5 6 

7 8 9

etc.

Can any one please suggest me a way how to do this?

You are looking for String.split. In your case, you need to split twice. Once with ; to split the string into chunks, then separately split each chunk with , to reach the array structure you are looking for.

function chunkSplit(str) {
    var chunks = str.split(';'), // split str on ';'
        nChunks = chunks.length, 
        n = 0;

    for (; n < nChunks; ++n) { 
        chunks[n] = chunks[n].split(','); // split each chunk with ','
    }

    return chunks;
}

var arr = chunkSplit("1,2,3;4,5,6;7,8,9;a,b,c;d,e,f;g,h,i");
