JS脚本在放大Web浏览器时不起作用

function resizePlayer(){
 if(jwplayer().getWidth() == 596) { 
 jwplayer().resize(1004,565); 
 } else {
 jwplayer().resize(596,335);
 }
 };

function resizePlayer(){
 if(jwplayer().getWidth() == 596) { 
 jwplayer().resize(1004,565); 
 } else {
 jwplayer().resize(596,335);
 }
 };

you need attach the listener to an element such as window :
window.onresize = resizePlayer;
