Firefox 浏览器拒绝全屏更改

Question

当我们点击我的网站元素时，我正尝试全屏显示它，它适用于 chrome、IE，但不适用于 firefox。

我去了microsoft fullscreen API，测试了他们的代码，这些浏览器都没有问题。

这是我想要全屏显示的网站部分。

<div class="wrap">
    <div class="signin">
        <div style="margin: 2px 0px -25px 10px;"><h1>Sign In or <a href="<?php echo $this->url(array('module' => 'default','controller'=>'paid-sign-up','action'=>'index'),null,true); ?>" style="color:#F00;text-decoration:none;">Signup</a></h1></div>
        <?php echo $this->signin(); ?>
        <span class="forget">
        <a href="<?php echo $this->url(array('module' => 'default','controller'=>'forgot-password','action'=>'index'),null,true); ?>">Forgotten Password?</a> </span>
    </div>

这里是我使用的脚本

    <script type="text/javascript">
  var inFullScreen = false; // flag to show when full screen

  var fsClass = document.getElementsByClassName("wrap");
  for (var i = 0; i < fsClass.length; i++) {
    fsClass[i].addEventListener("click", function (evt) {
      if (inFullScreen == false) {
        makeFullScreen(evt.target); // open to full screen
      } else {
        reset();
      }
    }, false);
  }


  function makeFullScreen(divObj) {
alert (divObj);
  if (divObj.requestFullscreen) {
alert ('standard');
        divObj.requestFullscreen();
    }
    else if (divObj.msRequestFullscreen) {
alert ('ms');
      divObj.msRequestFullscreen();
    }
    else if (divObj.mozRequestFullScreen) {
alert ('moz');
      divObj.mozRequestFullScreen();
    }
    else if (divObj.webkitRequestFullscreen) {
alert ('webkit');
      divObj.webkitRequestFullscreen();
    }
    inFullScreen = true;
    return;
  }

  function reset() {
    if (document.exitFullscreen) {
      document.exitFullscreen();
    }
    else if (document.msExitFullscreen) {
      document.msExitFullscreen();
    }
    else if (document.mozCancelFullScreen) {
      document.mozCancelFullScreen();
    }
    else if (document.webkitCancelFullScreen) {
      document.webkitCancelFullScreen();
    }
    inFullScreen = false;
    return;
  }


</script>

最后一个有用的信息，我的网站是一个 zent 框架网站，这就是为什么会有一些 PHP。

此代码段应该适用于大多数浏览器，包括。火狐浏览器。具体来说，Mozilla Firefox 坚持事件处理程序中的代码在 1 秒内执行。否则全屏请求将被拒绝。参考：Bug Report

HTML

<button id="view-fullscreen">Fullscreen</button>

Javascript

var viewFullScreen = document.getElementById("view-fullscreen");
if (viewFullScreen) {
  viewFullScreen.addEventListener("click", function() {
    var docElm = document.documentElement;
    if (docElm.requestFullscreen) {
      docElm.requestFullscreen();
    } else if (docElm.msRequestFullscreen) {
      docElm.msRequestFullscreen();
    } else if (docElm.mozRequestFullScreen) {
      docElm.mozRequestFullScreen();
    } else if (docElm.webkitRequestFullScreen) {
      docElm.webkitRequestFullScreen();
    }
  })
}
