禁用全屏Iframe重新加载

Question

我有以下代码，用于通过点击按钮使IFRAME进入全屏，

var button = document.querySelector('#container .button');
button.addEventListener('click', fullscreen);
// when you are in fullscreen, ESC and F11 may not be trigger by keydown listener. 
// so don't use it to detect exit fullscreen
document.addEventListener('keydown', function (e) {
console.log('key press' + e.keyCode);
});
// detect enter or exit fullscreen mode
document.addEventListener('webkitfullscreenchange', fullscreenChange);
document.addEventListener('mozfullscreenchange', fullscreenChange);
document.addEventListener('fullscreenchange', fullscreenChange);
document.addEventListener('MSFullscreenChange', fullscreenChange);
function fullscreen() {
// check if fullscreen mode is available
if (document.fullscreenEnabled || 
document.webkitFullscreenEnabled || 
document.mozFullScreenEnabled ||
document.msFullscreenEnabled) {

// which element will be fullscreen
var iframe = document.querySelector('#container iframe');
// Do fullscreen
if (iframe.requestFullscreen) {
iframe.requestFullscreen();
} else if (iframe.webkitRequestFullscreen) {
iframe.webkitRequestFullscreen();
} else if (iframe.mozRequestFullScreen) {
iframe.mozRequestFullScreen();
} else if (iframe.msRequestFullscreen) {
iframe.msRequestFullscreen();
}
}
else {
document.querySelector('.error').innerHTML = 'Your browser is not supported';
}
}
function fullscreenChange() {
if (document.fullscreenEnabled ||
document.webkitIsFullScreen || 
document.mozFullScreen ||
document.msFullscreenElement) {
console.log('enter fullscreen');
}
else {
console.log('exit fullscreen');
}
}

<div id="container">
<div class="top-left">
<button class="button">Ver Ecrã Completo</button>
</div>
<iframe src="http://google.pt" Title="google" frameborder="0"></iframe>
<div class="error"></div>
</div>

当我进入全屏时，我假装禁用刷新/重新加载，反之亦然，我是如何错过的，我该如何做到？

ps：我添加了谷歌作为例子。注意：要添加为SWF和JavaScript的Iframe。

已解决！

我忘记删除主代码上的以下代码：

var iframe=document.querySelector('iframe'(；iframe.src=iframe.src；
