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;

}
