javascript - Scope issue inside a custom object -


i think having scope visibility issue can't figure out exactly: when log variable displayatonce right result, try use buttons nothing in return. have tried log this.navbuttons empty set... don't what's wrong code.

<!-- html code --> <div id="nav"> <a href="#" data-dir="prev">previous</a> <a href="#" data-dir="next">next</a> </div>  /* js script jquery */ (function() {  var newsnavigator = {      init: function(config) {         this.navbuttons = config.navbuttons;         this.displayatonce = config.displayatonce;         this.counter = 0;         this.shownews();         this.enablenav();      },      shownews: function() {         console.log(this.displayatonce);     },      enablenav: function() {                     console.log(this.navbuttons);         this.navbuttons.on('click', function() {             console.log("clicked");         });     }  };  newsnavigator.init({     displayatonce: 3,     navbuttons: $('div#nav').find('a') }); })();

that happening because using (function())(); executes function immediately, maybe it's running code before dom ready

everything working fine in below demo

demo

put code inside document ready or @ least call initialize method inside doc ready block like

 $(function(){     newsnavigator.init({         displayatonce: 3,         navbuttons: $('div#nav').find('a')     }); });
