用html5 js实现点击一个按钮达到浏览器全屏效果

 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(); }

 if (document.exitFullscreen) { document.exitFullscreen(); } else if (document.mozCancelFullScreen) { document.mozCancelFullScreen(); } else if (document.webkitCancelFullScreen) { document.webkitCancelFullScreen(); } else if (document.msExitFullscreen) { document.msExitFullscreen(); } 

 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); 

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