按下ESC时切换Javascript全屏按钮

按下ESC时切换Javascript全屏按钮,javascript,html,dom,Javascript,Html,Dom,我有一个全屏模式的按钮,按钮上写着“开”或“关”,效果很好: <div class="onoffswitch" onclick="fullscreen()"> <input type="checkbox" name="onoffswitch" class="onoffswitch-checkbox" id="myonoffswitch"> <label class="onoffswitch-label" for="myonoffswitch">

我有一个全屏模式的按钮,按钮上写着“开”或“关”,效果很好:

<div class="onoffswitch" onclick="fullscreen()">
    <input type="checkbox" name="onoffswitch" class="onoffswitch-checkbox" id="myonoffswitch">
    <label class="onoffswitch-label" for="myonoffswitch">
        <span class="onoffswitch-inner"></span>
        <span class="onoffswitch-switch"></span>
    </label>
</div>
我以为我的问题已经解决了,但后来我发现当全屏按钮被点击时,
.click
也被触发。它将触发按钮两次

然后我尝试这样做以防止正常的点击反应:

<div class="onoffswitch" onclick="fullscreen(); return false;">
我做了一把小提琴,但它不起作用,我仍然发布它,因为这是一种更容易使用javascript的方法:

因为小提琴坏了,我会把它放在我的网站上,直到问题解决:问题解决了

如果有不清楚的地方,请告诉我, 谢谢

[编辑]
我自己解决的
**请尝试此代码**它工作正常。

全屏:
函数全屏(){
if((document.fullScreenElement&&document.fullScreenElement!==null)||
(!document.mozFullScreen&&!document.webkitIsFullScreen)){
if(document.documentElement.requestFullScreen){
document.documentElement.requestFullScreen();
}else if(document.documentElement.mozRequestFullScreen){
document.documentElement.mozRequestFullScreen();
}else if(document.documentElement.webkitRequestFullScreen){
document.documentElement.webkitRequestFullScreen(元素.允许键盘输入);
}
}否则{
如果(文档取消全屏){
document.cancelFullScreen();
}else if(document.mozCancelFullScreen){
document.mozCancelFullScreen();
}else if(document.webkitcancelfillscreen){
document.webkitcancelfulscreen();
}
$('.myswitch').removeClass('active'))
}
}
文件。添加的文件列表(“完整屏幕更改”,exitHandler);
文件。addEventListener(“webkitfullscreenchange”,exitHandler);
文件。添加的EventListener(“MozzullScreenChange”,exitHandler);
文件。添加的文件列表器(“MSFullscreenChange”,exitHandler);
函数exitHandler(){
如果(!document.fullscreenElement&&!document.webkitIsFullScreen&&!document.mozFullScreen&&!document.msFullscreenElement){
$('.myswitch').removeClass('active'))
document.getElementById(“myonoffswitch”)。单击();
console.log(“这不是全屏”);
$(“.onoffswitch复选框:选中+.onoffswitch标签.onoffswitch内部”).css(“右边距”,”);
}否则{
console.log(“此全屏”);
$(“.onoffswitch复选框:选中+.onoffswitch标签.onoffswitch内部”).css(“左边距”,”);
}
}

我突然发现我的切换按钮只是一个复选框,所以我试着这样做:
document.getElementById(“myonoffswitch”).checked=false

而且似乎效果很好

您好,您是否看到问题也在这里而没有按escape?我认为问题是显而易见的。当您在全屏模式下首先进入时,您还没有添加
exitHandler
,因此即使使用escape退出,一切都可以正常工作。但是,在全屏模式下和检测到更改后
<div class="onoffswitch" onclick="fullscreen(); return false;">
function fullscreen() {
    if ((document.fullScreenElement && document.fullScreenElement !== null) ||
        (!document.mozFullScreen && !document.webkitIsFullScreen)) {
        if (document.documentElement.requestFullScreen) {
            document.documentElement.requestFullScreen();
        } else if (document.documentElement.mozRequestFullScreen) {
            document.documentElement.mozRequestFullScreen();
        } else if (document.documentElement.webkitRequestFullScreen) {
            document.documentElement.webkitRequestFullScreen(Element.ALLOW_KEYBOARD_INPUT);
        }
    } else {
        if (document.cancelFullScreen) {
            document.cancelFullScreen();
        } else if (document.mozCancelFullScreen) {
            document.mozCancelFullScreen();
        } else if (document.webkitCancelFullScreen) {
            document.webkitCancelFullScreen();
        }
    }
}

document.addEventListener('fullscreenchange', exitHandler);
document.addEventListener('webkitfullscreenchange', exitHandler);
document.addEventListener('mozfullscreenchange', exitHandler);
document.addEventListener('MSFullscreenChange', exitHandler);

function exitHandler() {
// Any fullscreen change will trigger this function
// Normalscreen to fullscreen or fullscreen to normalscreen
// with the button or with ESC-key.
    if (!document.fullscreenElement && !document.webkitIsFullScreen && !document.mozFullScreen && !document.msFullscreenElement) {

    document.getElementById("myonoffswitch").click();
        // This event is always trickered, but it's meant to be trickered when ESCAPE is used,    

    } 
}
**Please try this code** It's Working fine.
