任何方式来防止/禁用浏览器中的CTRL + [key]快捷键？ [英] Any way to prevent/disable CTRL + [key] shortcuts in the browser?

问题描述

我知道很多人会对这个被问到的问题感到愤怒，但是...

我有一个使用WebGL和Pointer Lock API的游戏。由于很多游戏在CTRL上有蹲的性质，我想知道是否有任何可能的方法来停止像CTRL + S和CTRL + W这样的浏览器快捷方式。

目前我不得不严格禁止控件在其中有任何CTRL键。我为C设置了'蹲'，这也很常见，但我也有关于制作MMORPG风格游戏的想法，在这种游戏中，您将拥有多个操作栏，并且由于CTRL不可行，因此无法进行多种组合。注意：在Chrome中 Ctrl + W / kbd>是保留，请使用 window.onbeforeunload

试试这个（禁用 Ctrl + W 和 Ctrl + S ）：

  window.onbeforeunload = function（）{//防止Ctrl + W 
返回真的想退出游戏吗？; 
}; 
 
 document.onkeydown = function（e）{
 e = e || window.event; //获取事件
 if（e.ctrlKey）{
 var c = e.which || e.keyCode; //获取密钥代码
 switch（c）{
 case 83：// Block Ctrl + S 
 case 87：// Block Ctrl + W  -  Chrome中无法使用
 e.preventDefault（）; 
 e.stopPropagation（）; 
休息; 
} 
} 
}; 
  

I know a lot of people will be angry about this being asked but...

I have a game using WebGL and the Pointer Lock API. Due to the nature of a lot of games having 'crouch' on CTRL I was wondering if there was any possible way to stop browser shortcuts like CTRL + S and CTRL + W...

At the moment I'm having to harshly disallow controls to have any CTRL key in them. I have set 'crouch' to C which is also common but I also have ideas about making a MMORPG-style game where you would have several action bars of abilities and a lot of combinations wouldn't be possible due to CTRL not being viable.

解决方案

Note: In Chrome Ctrl+W is "reserved", use window.onbeforeunload

Try this (disable Ctrl+W and Ctrl+S):

window.onbeforeunload = function () {//Prevent Ctrl+W
    return "Really want to quit the game?";
};

document.onkeydown = function (e) {
    e = e || window.event;//Get event
    if (e.ctrlKey) {
        var c = e.which || e.keyCode;//Get key code
        switch (c) {
            case 83://Block Ctrl+S
            case 87://Block Ctrl+W --Not work in Chrome
                e.preventDefault();     
                e.stopPropagation();
            break;
        }
    }
};
