话不多说，直接上demo，你可以点击下面的图片看效果。
插件代码
(
function
(){
var
fullScreenApi = {
supportsFullScreen:
false
,
isFullScreen:
function
() {
return
false
; },
requestFullScreen:
function
() {},
cancelFullScreen:
function
() {},
fullScreenEventName:
''
,
prefix:
''
},
browserPrefixes =
'webkit moz o ms khtml'
.split(
' '
);
// check for native support
if
(
typeof
document.cancelFullScreen !=
'undefined'
) {
fullScreenApi.supportsFullScreen =
true
;
}
else
{
// check for fullscreen support by vendor prefix
for
(
var
i = 0, il = browserPrefixes.length; i < il; i++ ) {
fullScreenApi.prefix = browserPrefixes[i];
if
(
typeof
document[fullScreenApi.prefix +
'CancelFullScreen'
] !=
'undefined'
) {
fullScreenApi.supportsFullScreen =
true
;
break
;
}
}
}
// update methods to do something useful
if
(fullScreenApi.supportsFullScreen) {
fullScreenApi.fullScreenEventName = fullScreenApi.prefix +
'fullscreenchange'
;
fullScreenApi.isFullScreen =
function
() {
switch
(
this
.prefix) {
case
''
:
return
document.fullScreen;
case
'webkit'
:
return
document.webkitIsFullScreen;
default
:
return
document[
this
.prefix +
'FullScreen'
];
}
}
fullScreenApi.requestFullScreen =
function
(el) {
return
(
this
.prefix ===
''
) ? el.requestFullScreen() : el[
this
.prefix +
'RequestFullScreen'
]();
}
fullScreenApi.cancelFullScreen =
function
(el) {
return
(
this
.prefix ===
''
) ? document.cancelFullScreen() : document[
this
.prefix +
'CancelFullScreen'
]();
}
}
// jQuery plugin
if
(
typeof
jQuery !=
'undefined'
) {
jQuery.fn.requestFullScreen =
function
() {
return
this
.each(
function
() {
if
(fullScreenApi.supportsFullScreen) {
fullScreenApi.requestFullScreen(
this
);
}
});
};
}
window.fullScreenApi = fullScreenApi;
})();

调用代码
$(
function
(){
$(
'#fullscreenbtn'
).click(
function
(){
if
(window.fullScreenApi.supportsFullScreen){
window.fullScreenApi.requestFullScreen(document.getElementById(
'fullscreenbox'
));
}
else
{
alert(
'就你这浏览器，基本就告别全屏功能了'
);
}
});
});
|
HTML代码结构
<
a
id="fullscreenbtn">
<
img
id="fullscreenbox" style="display: block; margin-left: auto; margin-right: auto;" src="http://pic002.cnblogs.com/images/2012/277258/2012041400022949.gif" alt="" />
</

基于fullscreen功能，我们就可以做出很多效果，比如相册：

又比如视频中的全屏功能：
当然也不能不说我的HoorayOS中窗口全屏的使用：
