Filter JSON by key value
You should use filter method.
The filter() method creates a new array with all elements that pass the test implemented by the provided function.
Provided function is a callback which is applied to each element of the array.
var arr = [{"time":"2016-07-26 09:02:27","type":"aa"}, {"time":"2016-04-21 20:35:07","type":"ae"}, {"time":"2016-08-20 03:31:57","type":"ar"}, {"time":"2017-01-19 22:58:06","type":"ae"}, {"time":"2016-08-28 10:19:27","type":"ae"}, {"time":"2016-12-06 10:36:22","type":"ar"}, {"time":"2016-07-09 12:14:03","type":"ar"}, {"time":"2016-10-25 05:05:37","type":"ae"}, {"time":"2016-06-05 07:57:18","type":"ae"}, {"time":"2016-10-08 22:03:03","type":"aa"}, {"time":"2016-08-13 21:27:37","type":"ae"}, {"time":"2016-04-09 07:36:16","type":"ar"}, {"time":"2016-12-30 17:20:08","type":"aa"}, {"time":"2016-03-11 17:31:46","type":"aa"}, {"time":"2016-05-04 14:08:25","type":"ar"}, {"time":"2016-11-29 05:21:02","type":"ar"}, {"time":"2016-03-08 05:46:01","type":"ar"}, ];console.log(arr.filter(function(item){ return item.type == "ar"; }));Also, you can use a shorter way with arrow functions:
var filtered = arr.filter(a => a.type == "ar");
Using filter method you can filter the array to return only those elements which match a particular condition data.filter((x)=>x.type === "ar");
The filter method creates a new array with all elements that will pass the condition x.type === "ar"
var data =[{"time":"2016-07-26 09:02:27","type":"aa"},{"time":"2016-04-21 20:35:07","type":"ae"},{"time":"2016-08-20 03:31:57","type":"ar"},{"time":"2017-01-19 22:58:06","type":"ae"},{"time":"2016-08-28 10:19:27","type":"ae"},{"time":"2016-12-06 10:36:22","type":"ar"},{"time":"2016-07-09 12:14:03","type":"ar"},{"time":"2016-10-25 05:05:37","type":"ae"},{"time":"2016-06-05 07:57:18","type":"ae"},{"time":"2016-10-08 22:03:03","type":"aa"},{"time":"2016-08-13 21:27:37","type":"ae"},{"time":"2016-04-09 07:36:16","type":"ar"},{"time":"2016-12-30 17:20:08","type":"aa"},{"time":"2016-03-11 17:31:46","type":"aa"},{"time":"2016-05-04 14:08:25","type":"ar"},{"time":"2016-11-29 05:21:02","type":"ar"},{"time":"2016-03-08 05:46:01","type":"ar"},]; var result = data.filter((x)=>x.type === "ar");console.log(result);
You could use filter function. Check browser support first:
var result = a.filter(function(v){ return v.type==='ar';})Hope this helps.
var list = [ {"time":"2016-07-26 09:02:27","type":"aa"}, {"time":"2016-04-21 20:35:07","type":"ae"}, {"time":"2016-08-20 03:31:57","type":"ar"}, {"time":"2017-01-19 22:58:06","type":"ae"}, {"time":"2016-08-28 10:19:27","type":"ae"}, {"time":"2016-12-06 10:36:22","type":"ar"}, {"time":"2016-07-09 12:14:03","type":"ar"}, {"time":"2016-10-25 05:05:37","type":"ae"}, {"time":"2016-06-05 07:57:18","type":"ae"}, {"time":"2016-10-08 22:03:03","type":"aa"}, {"time":"2016-08-13 21:27:37","type":"ae"}, {"time":"2016-04-09 07:36:16","type":"ar"}, {"time":"2016-12-30 17:20:08","type":"aa"}, {"time":"2016-03-11 17:31:46","type":"aa"}, {"time":"2016-05-04 14:08:25","type":"ar"}, {"time":"2016-11-29 05:21:02","type":"ar"}, {"time":"2016-03-08 05:4601","type":"ar"},];var result = list.filter(function(obj, index){ return obj.type==='ar';})console.log(result);
