Vue提供的按键

.enter

.tab

.delete(捕获“删除”和“退格”键)

.esc

.space(空格)

.up

.dowm

.left

.right

可以通过以下自定义语句来自定义键位

Vue.config.keyCodes.键位 = 键码;

(如：Vue.config.keyCodes.F1 = 112;-----使用的时候可以 @keyup.F1=" 事件")

如果要使用组合键，则可以判断是否同时按下了这几个键，比如ctrl键、shift键以及alt键的组合使用就可以判断是否多按下了ctrl键、shift键以及alt键

document.onkeydown=function(event){

var e = event || window.event || arguments.callee.caller.arguments[0];

if(e && e.keyCode==27){ // 按 Esc

//要做的事情

}

if(e && e.keyCode==113){ // 按 F2

//要做的事情

}

if(e && e.keyCode==13){ // enter 键

//要做的事情

}

};

只要你定义了这些键的动作，你在浏览器里按下这些键就会响应，兼容目前所有浏览器。
