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.m**itFullscreen) {
- document.m**itFullscreen();
- }
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;
- }
