用html5 js实现浏览器全屏

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();  }//IE11else 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;  }
