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.m**itFullscreen) {

document.m**itFullscreen();

}

事件监听

document.addEventListener("fullscreenchange", function () {

fullscreenState.innerHTML = (document.fullscreen)? "" : "not ";}, false);

document.addEventListener("mozfullscreenchange", function () {

fullscreenState.innerHTML = (document.mozFullScreen)? "" : "not ";}, false);

document.addEventListener("webkitfullscreenchange", function () {

fullscreenState.innerHTML = (document.webkitIsFullScreen)? "" : "not ";}, false);

document.addEventListener("msfullscreenchange", function () {

fullscreenState.innerHTML = (document.msFullscreenElement)? "" : "not ";}, false);
