javascript - Why iframe player only destroy once -


when refresh page click on button popup shows , youtube video play via iframe , when close popup closes when play same video (without refreshing page), popup shows video played successfully. when click on close button, shows in console: "cannot read property 'id' of null". destroy player every time when click on close button.

$('#clicktoplayvideo').click(function(){   $('#popup').show();   var player;    ytdeferred.done(function(yt) {     player = new yt.player('player', {       height: '390',       width: '640',       videoid: 'osyqj2luhmw',       events: {         'onready': onplayerready,       }     });     $('#closev').click(function(){       player.destroy();       document.getelementbyid('abc').style.display = "none";     });   });   function onplayerready(event) {     event.target.playvideo();     player.addeventlistener("onstatechange", "myvar");   }   myvar = function (state) {     if (state.data === 0) {       alert("stack overflow rocks!");       player.destroy();     }   } });
