JS实现两个时间进行比较

<script type ="text/javascript" >

// 时间比较 function GetCurrentTime(flag) {

    var currentTime = "";

    var myDate = new Date();

    var year = myDate.getFullYear();

    var month = parseInt(myDate.getMonth().toString()) + 1; //month是从0开始计数的，因此要 + 1

    if (month < 10) {

        month = "0" + month.toString();

    }

    var date = myDate.getDate();

    if (date < 10) {

        date = "0" + date.toString();

    }

    var hour = myDate.getHours();

    if (hour < 10) {

        hour = "0" + hour.toString();

    }

    var minute = myDate.getMinutes();

    if (minute < 10) {

        minute = "0" + minute.toString();

    }

    var second = myDate.getSeconds();

    if (second < 10) {

        second = "0" + second.toString();

    }

    if(flag == "0")

    {

        currentTime = year.toString() + month.toString() + date.toString() + hour.toString() + minute.toString() + second.toString(); //返回时间的数字组合

    }

    else if(flag == "1")

    {

        currentTime = year.toString() + "/" + month.toString() + "/" + date.toString() + " " + hour.toString() + ":" + minute.toString() + ":" + second.toString(); //以时间格式返回

    }

    return currentTime; }

</script>
