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

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
