How to fetch comma separated values from mentioned string

I want to fetch comma separated IDs and types from below string.

I tried through split but that requires multiple split to fetch desired result.

Please suggest an efficient way to fetch desired output like like 1234,4321 using js/jquery.

var tempString=
'[{"id":"1234","desc":"description","status":"activated","type":"type","name":"NAME"},
  {"id":"4321","desc":"description1","status":"inactivated","type":"type","name":"NAME1"}]';

first off what you have above isn't a string, it is an array of objects.

BUT

if it were a string (like so )

var tempString = '[{"id":"1234","desc":"description","status":"activated","type":"type","name":"NAME"}]

[{"id":"4321","desc":"description1","status":"inactivated","type":"type","name":"NAME1"}]';

Then you would want to use something like .match(); https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/String/match

var IDs = tempString.match(/([0-9]+)/gi);

To get "1234,4321", you can do

var ids = tempString.map(function(v){return v.id}).join(',');

If you want to be compatible with IE8, then you can do

var ids = $.map(tempString, function(v){return v.id}).join(',');

Following question edit :

If tempString isn't an array but really a JSON string, then you'd do

var ids = $.map(JSON.parse(tempString), function(v){return v.id}).join(',');

You should use any Javascript parser api for JSON to decode the given string into keys and subsequent values. As mentioned by 'Miquel', jQuery has one

As pointed out, that's not a String in your example. Some quotation marks went missing.

At any rate, look into @dystroy's answer, but I think you are dealing with JSON objects, and you should probably be useing a json parser (or even javascripts raw eval if you must) and then fetch your components as object properties and arrays.
