本文实例讲述了JavaScript控制浏览器全屏显示。分享给大家供大家参考，具体如下：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>www.qb5200.com JS全屏显示</title>
</head>
<body>
<div onclick="launchFullscreen(document.documentElement);">全屏显示</div>
<div onclick="exitFullscreen()(document.documentElement);">退出全屏</div>
<!--launchFullscreen(document.documentElement);-->
</body>
</html>
<script>
// 判断各种浏览器，找到正确的方法
function launchFullscreen(element) {
if(element.requestFullscreen) {
element.requestFullscreen();
} else if(element.mozRequestFullScreen) {
element.mozRequestFullScreen();
} else if(element.webkitRequestFullscreen) {
element.webkitRequestFullscreen();
} else if(element.msRequestFullscreen) {
element.msRequestFullscreen();
}
}
// 判断浏览器种类
function exitFullscreen() {
if(document.exitFullscreen) {
document.exitFullscreen();
} else if(document.mozCancelFullScreen) {
document.mozCancelFullScreen();
} else if(document.webkitExitFullscreen) {
document.webkitExitFullscreen();
}
}
// 退出全屏模式!
exitFullscreen();
</script>
