简单地说,有没有办法在JavaScript中检测其他鼠标按键?其余的鼠标输入没有记录,所以我猜它不是标准实现。
有没有办法,比如图书馆,可以启用额外的鼠标按钮?

是的,你可以这样做,检查 MouseEvent.button ,请参阅下面的示例,它会检测3和4按钮点击。
某些指点设备提供或模拟更多按钮。要表示此类按钮,每个连续按钮(在二进制系列8,16,32,...中)的值必须加倍,如 https://www.w3.org/TR/DOM-Level-3-Events/#events-mouseevents
中所述
var whichButton = function (e) {
// Handle different event models
var e = e || window.event;
var btnCode;
if ('object' === typeof e) {
btnCode = e.button;
switch (btnCode) {
case 3:
console.log('Browser Back button clicked.');
break;
case 4:
console.log('Browser Forward button clicked.');
break;
default:
console.log('Unexpected code: ' + btnCode);
}
}
}
<button onmouseup="whichButton(event);" oncontextmenu="event.preventDefault();">Click with mouse...</button>
