Question

让我们看看，我有一个jquery解析的json对象，就像这样（但非常大）：

[
{answered: 0,
caller: 4,
callid: 4,
expired: 0,
groupid: 2,
location: "jubin",
name: "vahid",
personid: 3,
presense: 1367323732,
response: null,
text: null,
time: 1367336754,
type: 0},

{answered: 0,
caller: 6,
callid: 5,
expired: 0,
groupid: 2,
location: "jubin",
name: "vahid",
personid: 3,
presense: 1367323732,
response: null,
text: null,
time: 1367336766,
type: 0},

{answered: 0,
caller: 4,
callid: 4,
expired: 0,
groupid: 2,
location: "jubin",
name: "reza",
personid: 1,
presense: 1367392633,
response: null,
text: null,
time: 1367336754,
type: 0},

{answered: 0,
caller: 6,
callid: 5,
expired: 0,
groupid: 2,
location: "jubin",
name: null,
personid: 1,
presense: 1367392633,
response: null,
text: null,
time: 1367336766,
type: 0}
]

我喜欢这样的东西（短版）：

[
{
callid: 4,
name: {"vahid", "reza"}
},

{
callid: 5,
name: {"vahid", null}
} 
]

任何人都可以提供帮助，
我几乎尝试了所有的事情和ifs，但当然我在某个地方做错了谢谢你前进

Answer 1

尝试使用_，http://jsfiddle.net/sWDsM/3/

这会将data转换为arr[callid] = [name, ...]

之类的数组

var arr = _.inject(data, function (memo, row) {
    memo[row.callid] || (memo[row.callid] = []);
    if (row.name != null && memo[row.callid].indexOf(row.name) == -1) {
        memo[row.callid].push(row.name);
    }
    return memo;
}, []);

这将转换为你期望的

var result = [];
for (var key in arr) {
    result.push({callid: key, name: arr[key]});
}

万岁，我做到了！我的结果是：

function calllog(log){//given log is my primary array
    var oLog = [];
    var tmpLog = [];
    var LL = log.length;
    for (var i=0; i<LL; i++){
        var thisID = log[i].callid;
        if(oLog.indexOf(thisID)<0){
            oLog.push(thisID);
        }
    };
    for (j in oLog){
        var tmpholder = [];
        for (k in log){
            if (oLog[j] == log[k].callid){
                tmpholder.push(log[k].name);
            }
        }
        tmpLog.push({
            'callid': oLog[j], 'name': tmpholder
        })
    };
    $(document.body).data('calllog', tmpLog);
};

如何获得这个javascript对象的所需顺序？
