方法:

function doExchange(doubleArrays, fgf) {

    /// <param name="doubleArrays" type="type">二维数组</param>
    /// <param name="fgf" type="type">分隔符</param>
    /// <returns type=""></returns>
    if (fgf == undefined) fgf = ",";
    var len = doubleArrays.length;
    if (len >= 2) {
        var len1 = doubleArrays[0].length;
        var len2 = 0;
        try {
            len2 = doubleArrays[1].length;
        } catch (e) {
            var x = "";
        }

        var newlen = len1 * len2;
        var temp = new Array(newlen);
        var index = 0;
        for (var i = 0; i < len1; i++) {
            for (var j = 0; j < len2; j++) {
                temp[index] = doubleArrays[0][i] + fgf + doubleArrays[1][j];
                index++;
            }
        }
        var newArray = new Array(len - 1);
        for (var i = 2; i < len; i++) {
            newArray[i - 1] = doubleArrays[i];
        }
        newArray[0] = temp;
        return doExchange(newArray, fgf);
    }
    else {
        return doubleArrays[0];
    }
}
