想不想用最简短的js代码就能获取日期：前天、昨天、今天、明天、后天

废话不多说，代码说话：

    <title>js获取日期：前天、昨天、今天、明天、后天 - Liehuo.Net</title>
</head>
<body>
<script language="JavaScript" type="text/javascript">
    function GetDateStr(AddDayCount) {
        var dd = new Date();
        dd.setDate(dd.getDate()+AddDayCount);//获取AddDayCount天后的日期
        var y = dd.getFullYear();
        var m = dd.getMonth()+1;//获取当前月份的日期
        var d = dd.getDate();
        if (m < 10) m = "0" + m;
        if (d < 10) d = "0" + d;
        return y+"-"+m+"-"+d;
    }
    document.write("前天："+GetDateStr(-2));
    document.write("<br />昨天："+GetDateStr(-1));
    document.write("<br />今天："+GetDateStr(0));
    document.write("<br />明天："+GetDateStr(1));
    document.write("<br />后天："+GetDateStr(2));
    document.write("<br />大后天："+GetDateStr(3));
</script>
