這篇文章主要為大家詳細介紹了js實現(xiàn)窗口全屏示例，包含全屏事件、退出全屏事件等，具有一定的參考價值，感興趣的小伙伴們可以參考一下

前言

該 demo 包含全屏事件、退出全屏事件以及屏幕狀態(tài)改變的鉤子函數(shù)的封裝
以下是一個完整示例，只需整體拷貝下來運行即可(注意引入了 jquery)

請在這里查看示例☞ fullscreen示例

示例

<!DOCTYPE html>
<html lang="en">
<head>
 <meta charset="UTF-8">
 <title>demo</title>
 <script src="js/jquery-1.11.3.min.js"></script>
 <style>
  * {
   margin: 0;
   padding: 0;
  }
  /* 窗口全屏樣式 */
  html:-moz-full-screen { 
   background: grey; 
  } 
  html:-webkit-full-screen { 
   background: grey; 
  } 
  html:fullscreen { 
   background: grey; 
  }

  div {
   width: 100px;
   height: 100px;
   background: blue;
  }
  img {
   width: 80px;
   height: 80px;
  }
 </style>
</head>
<body>
 <button class="win-fullscreen">窗口全屏</button>
 <button class="div-fullscreen">div全屏</button>
 <button class="img-fullscreen">img全屏</button>
 <button class="exit-fullscreen">退出全屏</button>
 <div class="div">
  <img class="img" src="images/a.png">
 </div>
</body>
<script>
 /* 調(diào)用示例 */
 // 窗口全屏
 $('.win-fullscreen').on('click', function() {
  requestFullScreen(document.documentElement);
 });

 // div全屏
 $('.div-fullscreen').on('click', function() {
  requestFullScreen($('.div')[0]);
 });

 // img全屏
 $('.img-fullscreen').on('click', function() {
  requestFullScreen($('.img')[0]);
 });

 // 退出全屏
 $('.exit-fullscreen').on('click', function() {
  exitFull();
 });

 // 窗口狀態(tài)改變事件
 fullscreenchange(document, function(isFull) {
  console.log(isFull);
 });

 /* 封裝 */
 // 窗口狀態(tài)改變
 function fullscreenchange(el, callback) {
  el.addEventListener("fullscreenchange", function () { 
   callback && callback(document.fullscreen);
  }); 
  el.addEventListener("webkitfullscreenchange", function () { 
   callback && callback(document.webkitIsFullScreen);
  }); 
  el.addEventListener("mozfullscreenchange", function () { 
   callback && callback(document.mozFullScreen);
  }); 
  el.addEventListener("msfullscreenchange", function () { 
   callback && callback(document.msFullscreenElement);
  });
 }

 // 全屏
 function requestFullScreen(element) {
  var requestMethod = element.requestFullScreen || //W3C
  element.webkitRequestFullScreen || //Chrome等
  element.mozRequestFullScreen || //FireFox
  element.msRequestFullScreen; //IE11
  if (requestMethod) {
   requestMethod.call(element);
  }else if (typeof window.ActiveXObject !== "undefined") {//for Internet Explorer
   var wscript = new ActiveXObject("WScript.Shell");
   if (wscript !== null) {
    wscript.SendKeys("{F11}");
   }
  }
 }

 //退出全屏
 function exitFull() {
  var exitMethod = document.exitFullscreen || //W3C
  document.mozCancelFullScreen || //Chrome等
  document.webkitExitFullscreen || //FireFox
  document.webkitExitFullscreen; //IE11
  if (exitMethod) {
   exitMethod.call(document);
  }else if (typeof window.ActiveXObject !== "undefined") {//for Internet Explorer
   var wscript = new ActiveXObject("WScript.Shell");
   if (wscript !== null) {
    wscript.SendKeys("{F11}");
   }
  }
 }
</script>
