javascript - Get function associated with setTimeout or setInterval -

let's assume have timeout id returned settimeout or setinterval.

can get, in way, original function or code, associated it?

something this:

var timer_id = settimeout(function() {     console.log('hello stackoverflowers!'); }, 100000);  var fn = timer_id.get_function(); // desired method fn(); // output: 'hello stackoverflowers!' 

you can put wrapper around settimeout - threw 1 (after few iterations of testing...)

(function() {      var cache = {};       var _settimeout = window.settimeout;      var _cleartimeout = window.cleartimeout;       window.settimeout = function(fn, delay) {          var id = _settimeout(function() {              delete cache[id];  // ensure map cleared on completion              fn();          }, delay);          cache[id] = fn;          return id;      }       window.cleartimeout = function(id) {          delete cache[id];          _cleartimeout(id);      }       window.gettimeout = function(id) {          return cache[id];      } })(); 

nb: won't work if use string callback. no 1 that, they..?

nor support passing es5 additional parameters callback function, although easy support.
