转移事件+选项+命令+左键单击

Question

使用javascript（jquery okay），如何在shift +选项+命令+左键单击对象时触发事件？

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

看起来像这样的东西应该用于记录密钥（但它根本不用^^）而且，我如何跟踪点击？

谢谢！

试试这个：

现场演示 （适用于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();
    }
});
