浏览数：26 / 时间：2015年06月09日

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;  
}
