js实现全屏

function full(){
var docElm = document.documentElement;
//W3C
if (docElm.requestFullscreen) {
docElm.requestFullscreen();
}
//FireFox
else if (docElm.mozRequestFullScreen) {
docElm.mozRequestFullScreen();
}
//Chrome等
else if (docElm.webkitRequestFullScreen) {
docElm.webkitRequestFullScreen();
}
//IE11
else if (elem.msRequestFullscreen) {
elem.msRequestFullscreen();
}
退出全屏

if (document.exitFullscreen) {
document.exitFullscreen();
}
else if (document.mozCancelFullScreen) {
document.mozCancelFullScreen();
}
else if (document.webkitCancelFullScreen) {
document.webkitCancelFullScreen();
}
else if (document.msExitFullscreen) {
document.msExitFullscreen();
}
}

//注意这个一定要是用户来触发这个
