推荐答案

您正在寻找的 String.split 。你的情况，你需要拆分的两倍。一旦与; 来分割字符串成块，然后分别每块与分裂，到达阵列结构你寻找。

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");
