var results = [], arr = {} //arr就是你的json数组，results是转后的结果;
for (var i in arr.success) {
var objs = arr.success[i];
for(var j in objs){
if(results[j]==undefined){
results[j]=[];
}
var obj = objs[j];
results[j].push(obj.t)
}
}

以下是运行结果,你的json代码有重复的C1

不多说了，直接上代码！

var json={
                "success": {
                    "1": [
                        {
                        "t": "A1",
                        "c": "2017-06-28 19:02:46"
                        },
                        {
                        "t": "A2",
                        "c": "2017-06-28 19:02:46"
                        }
                    ],
                    "2": [
                        {
                        "t": "B1",
                        "c": "2017-06-28 18:59:21"
                        },
                        {
                        "t": "B2",
                        "c": "2017-06-28 18:59:21"
                        }
                        ],
                    "3": [
                        {
                        "t": "C1",
                        "c": "2017-06-28 19:00:27"
                        },
                        {
                        "t": "C2",
                        "c": "2017-06-28 19:00:27"
                        }
                    ]
                }
            };
            var arr=json.success["1"],re_arr=[],narr=[];
            for(var key in json.success){
                narr=json.success[key] || [];
                for(var i=0,len=narr.length;i<len;i++){
                    if(!re_arr[i] || !re_arr[i] instanceof Array){      //判断当前re_arr[i]是否为数组
                        re_arr[i]=[narr[i]["t"]];       //将re_arr[i]设置为数组
                    }else{
                        re_arr[i].push(narr[i]["t"]);       //push数组
                    }
                }
            }
            console.log(re_arr);

追问大兄弟，你的arr没用到，不过效果好像就是我要的，谢谢了

没太懂你意思，【A1，B1，C1】对应什么
