js取得页面中的日期正则怎么写啊。

private string ClHtml(string html)
    {
        string str = "";
        string strtemp = "";
        string[] s;
        int n = 0;
        Regex r = new Regex("(([0-9]{2})(0[48]|[2468][048]|[13579][26])|((0[48]|[2468][048]|[3579][26])00))-02-29");
        MatchCollection ms = r.Matches(html);         foreach (Match m in ms)
        {             try
            {
                str = m.Groups[1].Value;                 str = "<div class=\"" + str;
                str = str.Replace("<script type='", "");             }
            catch { }
        }

看不懂啊楼上的能不能写得完整一点啊要javascript的不用java实现。
/*@校验日期*/
function isDate(dateval){
    var arr = new Array();

    if(dateval.indexOf("-") != -1)
{
        arr = dateval.toString().split("-");
    }
else
{
        return false;
    }

    if(arr[0].length == 4)
{
        var date = new Date(arr[0],arr[1]-1,arr[2]);
        if(date.getFullYear()==arr[0] && date.getMonth()==arr[1]-1 && date.getDate()==arr[2])
{
            return true;
        }
    }

    return false;
};
不知道是不是要这样的
