用html5 js实现点击一个按钮达到浏览器全屏效果

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; }
