这是我按你的代码上修改的,你可以看下。图片用的是我自己的,所以图片路径不一样,注意。

jQuery写的,在文本框获得焦点时可通过左右方向键来增减月份值:
HTML:
<!DOCTYPE html><html>
<head>
<meta charset='utf-8'>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
</head>
<body>
<input type="text" id="dateBox" />
</body>
</html>
JS:
var date = new Date()// 初始化日期的日、时、分、秒为0,避免闰年等引起的跳月问题
// (例如当前日期是2012-01-31,如果不置日为0,则按下右键时会直接跳到3月)
date.setDate(0)
date.setHours(0, 0, 0, 0)
function numFormat(num){
return (num <10 ? '0' : '') + num
}
function showDate(){
$('#dateBox').val(date.getFullYear() + '-' + numFormat(date.getMonth() + 1))
}
showDate() // 初始化显示
// 绑定键盘事件响应
$('#dateBox').keydown(function(e){
if (e.which == 37){
// 左方向键
date.setMonth(date.getMonth() - 1)
e.preventDefault()
} else if(e.which == 39) {
// 右方向键
date.setMonth(date.getMonth() + 1)
e.preventDefault()
}
showDate() // 更新日期显示
})
