视频全屏：allowFullScreen="true"
eg: <iframe src="" allowFullScreen="true" width="1024" height="768"></iframe>
取消视频全屏：document.webkitCancelFullScreen();
获取iframe中页面的元素：
var parentWin = parent.document.getElementById("ID").contentWindow;
var video = parentWin.document.getElementsByTagName("video");
swf背景透明：wmode=transparent
eg: <embed src="demo.swf" width="1024" height="768" wmode=transparent type="" >
使用FancyBox:
function loadSyFancybox () {
var settings = {
'transitionIn': 'fade',
'transitionOut': 'fade',
'titlePosition': 'over',
'cyclic': false,
'titleFormat': function(title) {
return '<span ).fancybox(settings);
//鼠标移开自动关闭
$("a[rel=syImg]").fancybox(settings).hover(function() {
});
});
}
