javascript - Uncaught typeerror: Object #<object> has no method 'method' -

so here's object 'playerturnobj'

function playerturnobj(set_turn) {     this.playerturn=set_turn;     function setturn(turntoset) {         this.playerturn=turntoset;     }     function getturn() {         return this.playerturn;     } } 

and here i'm doing it

var turn = new playerturnobj(); turn.setturn(1); 

so try make script setturn() method in playerturnobj() save 'turn' in game i'm making. problem is, not turn.setturn(1); part because keep getting error above

what doing wrong? searched, not find exact answer question.

this not way javascript works. "constructor" function contains inline functions not visible outside of scope of playerturnobj. variable turn not have method setturn defined, error message states correctly. want this:

function playerturnobj(set_turn) {     this.playerturn=set_turn; }  playerturnobj.prototype = {     setturn: function(turntoset) {         this.playerturn=turntoset;     },     getturn: function() {         return this.playerturn;     } }; 

now variable turn has 2 methods setturn , getturn operate on instance created new.
