用html5 js實現瀏覽器全屏

標籤：c   class   code   java   tar   http   

項目中需要將後台瀏覽器的視窗全屏，也就是我們點擊一個按鈕要實現按F11全屏的效果。 在HTML5中,W3C制定了關於全屏的API，就可以實現全螢幕的效果，也可以讓頁面中的圖片，視頻等全屏目前只有google chrome 15 +, safri5.1+,firfox10+,IE11支援

全屏?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

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(); }

事件監聽?

1 2 3 4 5 6 7 8 9 10

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);
