用html5 js实现点击一个按钮达到浏览器全屏效果_javascript技巧

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

复制代码代码如下:

 
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

复制代码代码如下:

 
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

复制代码代码如下:

 
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

复制代码代码如下:

 
html:-moz-full-screen { 
background: red; 
} 

html:-webkit-full-screen { 
background: red; 
} 

html:fullscreen { 
background: red; 
}
