键盘event.which属性

IE中,只有keyCode属性,而FireFox中有which和charCode属性

event.which属性对DOM原生的event.keyCode和event.charCode进行了标准化。

function keypress(e){    e = e || window.event;    var currKey = e.which || e.charCode || e.keyCode;var keyName = String.fromCharCode(currKey);    console.log("按键码: " + currKey + " 字符: " + keyName);}document.onkeypress = function(e){    keypress(e);}
