是否有能力捕捉任何按键?即 Ctrl + Shift + Alt 按键(没有其他按键)。

在下面的代码段中(在 Chrome 下检查),只有在按下其他“常规”键时,我才能捕获移位。

更新 :

<html>
<head>
    <script>
        function onKeyPressed(event) {
            event = event || window.event;
            var code = event.keyCode;
            var key = String.fromCharCode(event.keyCode);
            var shift = event.shiftKey;
            var alt = event.altKey;
            var ctrl = event.ctrlKey;
            var which = event.which;
            var str = "code = " + code + "\n" +
                      "key = " + key + "\n" +
                      "shift = " + shift + "\n" +
                      "alt = " + alt + "\n" +
                      "ctrl = " + ctrl + "\n" +
                      "which = " + which;
            alert(str);
        };

        function onClick(event) {
            event = event || window.event;
            var x = event.clientX;
            var y = event.clientY;
            var str = "x = " + x + "\n" +
                      "y = " + y;
            alert(str);
        };

        function onKeyUp(event) {
            alert("onKeyUp");
        };

        function onKeyDown(event) {
            alert("onKeyDown");
        }
    </script>
</head>
<body onmousedown="onClick(event)" onkeypress="onKeyPressed(event)" onkeyup="onKeyUp(event)" onkeydown="onKeyDown(event)"></body>
</html>

如何捕获这些 key ?

最佳答案

有一个非常好的新 JS 库,它在跟踪浏览器中的键盘事件方面做得很好。

它叫做捕鼠器。这是链接:http://craig.is/killing/mice

希望有帮助。
