根据时间和日期对对象数组进行排序

Question

I have a json object like this:

{
    "1":["Test Event 1","5","interview","08:30:00","2016-05-28","1"],
    "2":["Test 2","2","Lesser Important Items","08:30:00","2016-05-27","0"],
    "3":["Test Event 4","5","meeting","08:30:00","2016-06-12","1"],
    "4":["","0","Lesser Important Items","08:30:00","2016-06-12","0"],
    "5":["","0","Lesser Important Items","08:30:00","2016-06-12","0"],
    "6":["Test Event 3","1","interview","19:30:00","2016-05-29","1"]
 }

I want to sort this data On the basis of the time and date, after looking on stack, i found this :

jsonData.sort(function(a, b) {
    return a.time - b.time;
})

but this ain't doing any job and instead saying that jsonData.sort is not a function

Answer 1

The sort() method can only apply applied to array, the provided data is an object.

If you just want the sorted index array

 var data = { "1": ["Test Event 1", "5", "interview", "08:30:00", "2016-05-28", "1"], "2": ["Test 2", "2", "Lesser Important Items", "08:30:00", "2016-05-27", "0"], "3": ["Test Event 4", "5", "meeting", "08:30:00", "2016-06-12", "1"], "4": ["", "0", "Lesser Important Items", "08:30:00", "2016-06-12", "0"], "5": ["", "0", "Lesser Important Items", "08:30:00", "2016-06-12", "0"], "6": ["Test Event 3", "1", "interview", "19:30:00", "2016-05-29", "1"] }; var res = Object.keys(data) // get object keys array .sort(function(a, b) { // sort the key array based on the date and time // convert to date and get difference for sorting return new Date(data[a][4] + ' ' + data[a][3]) - new Date(data[b][4] + ' ' + data[b][3]); }) console.log(res)

Or if you want to convert it to a sorted array based on the time and date then do something like this,

 var data = { "1": ["Test Event 1", "5", "interview", "08:30:00", "2016-05-28", "1"], "2": ["Test 2", "2", "Lesser Important Items", "08:30:00", "2016-05-27", "0"], "3": ["Test Event 4", "5", "meeting", "08:30:00", "2016-06-12", "1"], "4": ["", "0", "Lesser Important Items", "08:30:00", "2016-06-12", "0"], "5": ["", "0", "Lesser Important Items", "08:30:00", "2016-06-12", "0"], "6": ["Test Event 3", "1", "interview", "19:30:00", "2016-05-29", "1"] }; var res = Object.keys(data) // get object keys array .sort(function(a, b) { // sort the key array based on the date and time // convert to date and get difference for sorting return new Date(data[a][4] + ' ' + data[a][3]) - new Date(data[b][4] + ' ' + data[b][3]); }).map(function(v) { // use map to generate the object array return data[v] // get object from the data }); console.log(res) 

---

In case if you want to re-index based the object keys then do something like this using sorted object array

 var data = { "1": ["Test Event 1", "5", "interview", "08:30:00", "2016-05-28", "1"], "2": ["Test 2", "2", "Lesser Important Items", "08:30:00", "2016-05-27", "0"], "3": ["Test Event 4", "5", "meeting", "08:30:00", "2016-06-12", "1"], "4": ["", "0", "Lesser Important Items", "08:30:00", "2016-06-12", "0"], "5": ["", "0", "Lesser Important Items", "08:30:00", "2016-06-12", "0"], "6": ["Test Event 3", "1", "interview", "19:30:00", "2016-05-29", "1"] }; Object.keys(data) // get object keys array .sort(function(a, b) { // sort the key array based on the date and time // convert to date and get difference for sorting return new Date(data[a][4] + ' ' + data[a][3]) - new Date(data[b][4] + ' ' + data[b][3]); }).map(function(v) { // use map to generate the object array return data[v] // get object from the data }).forEach(function(v, i) { data[i + 1] = v; // update based on the sorted array }) console.log(data) 

Answer 2

You cant sort object but you can sort array of object keys

 var obj = { "1": ["Test Event 1", "5", "interview", "08:30:00", "2016-05-28", "1"], "2": ["Test 2", "2", "Lesser Important Items", "08:30:00", "2016-05-27", "0"], "3": ["Test Event 4", "5", "meeting", "08:30:00", "2016-06-12", "1"], "4": ["", "0", "Lesser Important Items", "08:30:00", "2016-06-12", "0"], "5": ["", "0", "Lesser Important Items", "08:30:00", "2016-06-12", "0"], "6": ["Test Event 3", "1", "interview", "19:30:00", "2016-05-29", "1"] } var sort = Object.keys(obj).sort(function(a, b) { return Date.parse(obj[a][4]) - Date.parse(obj[b][4]) || Date.parse(obj[a][3].replace(/:/g, ' ')) - Date.parse(obj[b][3].replace(/:/g, ' ')); }) console.log(sort) 

Then you can use that sorted array to get object values DEMO

Answer 3

First of all, it is not an array it is an object. You need to convert this to array first.

var obj = {
    "1":["Test Event 1","5","interview","08:30:00","2016-05-28","1"],
    "2":["Test 2","2","Lesser Important Items","08:30:00","2016-05-27","0"],
    "3":["Test Event 4","5","meeting","08:30:00","2016-06-12","1"],
    "4":["","0","Lesser Important Items","08:30:00","2016-06-12","0"],
    "5":["","0","Lesser Important Items","08:30:00","2016-06-12","0"],
    "6":["Test Event 3","1","interview","19:30:00","2016-05-29","1"]
 }
var arr = Object.keys(obj).map(function(key){ return [key, obj[key]] });

Now you can sort it on the date and time as

arr.sort(function(a,b){ 
  var da = a[1][4], ta = a[1][3], db = b[1][4], tb = b[1][3];  
  da = da.split("-").map(function(val){ return parseInt(val,10); }); 
  ta = ta.split(":").map(function(val){ return parseInt(val,10); });
  db = db.split("-").map(function(val){ return parseInt(val,10); }); 
  tb = tb.split(":").map(function(val){ return parseInt(val,10); });

  var dateA = new Date( da[0], da[1]-1, da[2], ta[0], ta[1], ta[2] );
  var dateB = new Date( db[0], db[1]-1, db[2], tb[0], tb[1], tb[2] );
  return dateA.getTime() -dateB.getTime();
})

DEMO

 var obj = { "1":["Test Event 1","5","interview","08:30:00","2016-05-28","1"], "2":["Test 2","2","Lesser Important Items","08:30:00","2016-05-27","0"], "3":["Test Event 4","5","meeting","08:30:00","2016-06-12","1"], "4":["","0","Lesser Important Items","08:30:00","2016-06-12","0"], "5":["","0","Lesser Important Items","08:30:00","2016-06-12","0"], "6":["Test Event 3","1","interview","19:30:00","2016-05-29","1"] } var arr = Object.keys(obj).map(function(key){ return [key, obj[key]] }); arr.sort(function(a,b){ var da = a[1][4], ta = a[1][3], db = b[1][4], tb = b[1][3]; da = da.split("-").map(function(val){ return parseInt(val,10); }); ta = ta.split(":").map(function(val){ return parseInt(val,10); }); db = db.split("-").map(function(val){ return parseInt(val,10); }); tb = tb.split(":").map(function(val){ return parseInt(val,10); }); var dateA = new Date( da[0], da[1]-1, da[2], ta[0], ta[1], ta[2] ); var dateB = new Date( db[0], db[1]-1, db[2], tb[0], tb[1], tb[2] ); return dateA.getTime() -dateB.getTime(); }) console.log(arr); 

Answer 4

Your json object is not well formated, it should be something like :

{
    {
       "even_id":"1",
       "event_name":"Test Event",
       "event_watever":"1",
       "event_time":"08:30:00",
       "event_date":"2016-05-28"
    },
    {
       "even_id":"2",
       "event_name":"Test Event2",
       "event_watever":"5",
       "event_time":"08:30:00",
       "event_date":"2016-05-28"
    }
}

And, with that, you loop over each event and you sort them by event_date ( + event_time if date are equals) in a new Array.
