项目中需要将后台浏览器的窗口全屏，也就是我们点击一个按钮要实现按F11全屏的效果。在HTML5中,W3C制定了关于全屏的API，就可以实现全屏幕的效果，也可以让页面中的图片，视频等全屏目前只有google chrome 15 +, safri5.1+,firfox10+,IE11支持

全屏

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();
}

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);

全屏样式设置

在浏览器全屏的使用我们还可以进行样式设置

html:-moz-full-screen {  

    background: red;  
}  

html:-webkit-full-screen {  

    background: red;  
}  

html:fullscreen {  

    background: red;  
}
