JSON,数组根据字段分组

function GroupbyName(data, Name) { //data数据源，Name 根据什么字段分组
    var map = {},
      dest = [];
    for (var i = 0; i < data.length; i++) {
        var ai = data[i];
        if (!map[ai[Name]]) {
            dest.push({
                name: ai[Name],
                data: [ai]
            });
            map[ai[Name]] = ai;
        } else {
            for (var j = 0; j < dest.length; j++) {
                var dj = dest[j];
                if (dj.name == ai[Name]) {
                    dj.data.push(ai);
                    break;
                }
            }
        }
    }
    return dest;
}
