I've removed video references, try that:
我已经删除了视频参考，试试看：
(function(window, document){
var $ = function(selector,context){return(context||document).querySelector(selector)};
var iframe = $("iframe"),
domPrefixes = 'Webkit Moz O ms Khtml'.split(' ');
var fullscreen = function(elem) {
var prefix;
// Mozilla and webkit intialise fullscreen slightly differently
for ( var i = -1, len = domPrefixes.length; ++i < len; ) {
prefix = domPrefixes[i].toLowerCase();
if ( elem[prefix + 'EnterFullScreen'] ) {
// Webkit uses EnterFullScreen for video
return prefix + 'EnterFullScreen';
break;
} else if( elem[prefix + 'RequestFullScreen'] ) {
// Mozilla uses RequestFullScreen for all elements and webkit uses it for non video elements
return prefix + 'RequestFullScreen';
break;
}
}
return false;
};
// Webkit uses "requestFullScreen" for non video elements
var fullscreenother = fullscreen(document.createElement("iframe"));
if(!fullscreen) {
alert("Fullscreen won't work, please make sure you're using a browser that supports it and you have enabled the feature");
return;
}
$("#fullscreeniframe").addEventListener("click", function(){
// iframe fullscreen and non video elements in webkit use request over enter
iframe[fullscreenother]();
}, false);
})(this, this.document);
