javascript - shift+option+command+左键点击事件

Question

使用javascript（jquery好的），我怎么能在shift+option+command+左键单击一个对象时触发一个事件？

$(document).on('keypress', function(e) {
        if( e.keyCode == 224 && e.keyCode == 16 && e.keyCode == 18 ){
               console.log('keys pressed');
        }
});

似乎这样的东西应该适用于记录键（但它根本不起作用 ^^ ）而且，我如何跟踪点击？

谢谢！

尝试这个：

现场演示 （Mac OS）：http: //jsfiddle.net/NDuDZ/2/

代码：

//Combination: Shift+Option+Command+LeftClick

//Shift Firefox, Safari, Chrome, Opera keyCode: 16
//Option Firefox, Safari, Chrome, Opera keyCode: 18
//Command Firefox keyCode: 224
//Command Chrome, Safari keyCode: 91
//Command Opera keyCode: 17

var isOption = false;
var isCommand = false;
var isLeftClick = false;

$(document).on('keyup', function(e){
    if(e.which == 91 || e.which == 224 || e.which == 17) isCommand = false;
    if(e.which == 18) isOption = false;
});

$(document).on('click', function(e){
    isLeftClick = true;
});

$(document).on('keyup', function(e){
    if(e.which == 91 || e.which == 224 || e.which == 17) isCommand = true;
    if(e.which == 18) isOption = true;
    if(e.which == 16 && isOption && isCommand && isLeftClick) {
       alert('Shift+Option+Command+LeftClick invoked!');
       e.preventDefault();
    }
});
