当我按下键盘上的两个键时,如何同时获得两个代码?
在里面,我只得到一个keyCode
document.onkeydown = function(e)
{ var key = e.keyCode ? e.keyCode : e.which;
text.innerHTML += key; };
查看此处JavaScript同时按下多个键

zsvar log = $('#log')[0],
pressedKeys = [];
$(document.body).keydown(function (evt) {
var li = pressedKeys[evt.keyCode];
if (!li) {
li = log.appendChild(document.createElement('li'));
pressedKeys[evt.keyCode] = li;
}
$(li).text('Down: ' + evt.keyCode);
$(li).removeClass('key-up');
});
$(document.body).keyup(function (evt) {
var li = pressedKeys[evt.keyCode];
if (!li) {
li = log.appendChild(document.createElement('li'));
}
$(li).text('Up: ' + evt.keyCode);
$(li).addClass('key-up');
});
