您可能想尝试以下属性:

按钮- (caniuse); Which - (caniuse)(弃用)。

function onMouseDown(e)
{
    if (e.which === 1 || e.button === 0)
    {
        console.log('Left mouse button at ' + e.clientX + 'x' + e.clientY);
    }

    if (e.which === 2 || e.button === 1)
    {
        console.log('Middle mouse button at ' + e.clientX + 'x' + e.clientY);
    }

    if (e.which === 3 || e.button === 2)
    {
        console.log('Right mouse button at ' + e.clientX + 'x' + e.clientY);
    }

    if (e.which === 4 || e.button === 3)
    {
        console.log('Backward mouse button at ' + e.clientX + 'x' + e.clientY);
    }

    if (e.which === 5 || e.button === 4)
    {
        console.log('Forward mouse button at ' + e.clientX + 'x' + e.clientY);
    }
}

window.addEventListener("mousedown", onMouseDown);

document.addEventListener("contextmenu", function(e)
{
    e.preventDefault();
});

操作系统

On Windows and Linux there are modifier keys Alt, Shift and Ctrl. On Mac there’s one more: Cmd, corresponding to the property metaKey... Even if we’d like to force Mac users to Ctrl+click – that’s kind of difficult. The problem is: a left-click with Ctrl is interpreted as a right-click on MacOS, and it generates the contextmenu event, not click like Windows/Linux. So if we want users of all operating systems to feel comfortable, then together with ctrlKey we should check metaKey. For JS-code it means that we should check if (event.ctrlKey || event.metaKey)...

在本章中，我们将详细介绍鼠标事件及其属性……

使用jQuery库处理事件

$(window).on("contextmenu", function(e)
{
   alert("Right click");
})

For track right click 

window.oncontextmenu = () =>{

console.log("Right click")

}

仅适用于右键单击

看看下面的jQuery代码:

$("#myId").mousedown(function(ev){
      if(ev.which == 3)
      {
            alert("Right mouse button clicked on element with id myId");
      }
});

的值为:

1为左键 2为中间按钮 3为右键

正如其他人所提到的，可以通过通常的鼠标事件(鼠标下拉、鼠标上拉、单击)来检测鼠标右键。但是，如果您在弹出右键菜单时寻找触发事件，那么就找错地方了。右键单击/上下文菜单也可以通过键盘(shift+F10或上下文菜单键在Windows和一些Linux)访问。在这种情况下，你正在寻找的事件是oncontextmenu:

window.oncontextmenu = function ()
{
    showCustomMenu();
    return false;     // cancel default menu
}

至于鼠标事件本身，浏览器为事件对象设置了一个属性，可以从事件处理函数中访问:

document.body.onclick = function (e) {
    var isRightMB;
    e = e || window.event;

    if ("which" in e)  // Gecko (Firefox), WebKit (Safari/Chrome) & Opera
        isRightMB = e.which == 3; 
    else if ("button" in e)  // IE, Opera 
        isRightMB = e.button == 2; 

    alert("Right mouse button " + (isRightMB ? "" : " was not") + "clicked!");
}
