javascript - Perform a single function on multiple object -

is possible perform single function on multiple objects e.g. grouping them. want like:

{object1, object2, object3}.tofront(); 

while you've accepted answer, possible in similar manner either natively through javascript 1.6/ecmascript 5^th edition:

function logelementid(element, index, array) {     var el = array[index],         prop = el.textcontent ? 'textcontent' : 'innertext';     el[prop] = el.id; }  [document.getelementbyid('one'), document.getelementbyid('two')].foreach(logelementid); 

js fiddle demo.

or extending object prototype:

function dostuff (el) {     console.log(el); };  object.prototype.actongroup = function(func){     var els = this.length ? : [this];     (var = 0, len = els.length; i<len; i++){         func(els[i]);     }     return this; };  document.getelementsbytagname('div').actongroup(dostuff); document.getelementbyid('one').actongroup(dostuff); 

js fiddle demo.

or by, similarly, extending array prototype:

function dostuff (el) {     console.log(el); }; array.prototype.actongroup = function(func){     var els = this.length ? : [this];     (var = 0, len = els.length; i<len; i++){         func(els[i]);     }     return this; };  [document.getelementbyid('one'), document.getelementbyid('two')].actongroup(dostuff);

incidentally, if you'd provide foreach() alternative users without (relatively) up-to-date javascript implementations, mozilla developer network page foreach() offers following '[an] algorithm 100% true ecma-262, 5th edition':
