日期戳格式转换

不多说 上源码：

function formatDate(dateString) {
    dateString = dateString.replace("/", "").replace("/", "").replace("Date", "").replace("(", "").replace(")", "").replace("-", "");
    var date = new Date(parseFloat(dateString));
    var year = date.getFullYear();
    var m = date.getMonth() + 1;
    var d = date.getDate();
    var reM = "" + m;
    if (reM.length == 1) {
        reM = "0" + m;
    }
    var reD = "" + d;
    if (reD.length == 1) {
        reD = "0" + d;
    }

    var h = "" + date.getHours();
    h = (h.length == 1) ? ("0" + h) : h;
    var M = "" + date.getMinutes();
    M = (M.length == 1) ? ("0" + M) : M;
    var s = "" + date.getSeconds();
    s = (s.length == 1) ? ("0" + s) : s;
    return year + "-" + reM + "-" + reD + " " + h + ":" + M + ":" + s;
}

转换后格式为：

     yyyy-mm-dd hh:MM:ss

注意：日期和时间之间存在空格。
