在JavaScript中，利用三元运算符生成当前日期yyyy-MM-dd

<script type="text/javascript">

    //得到当前时间yyyy-MM-dd

    var myDate = new Date();

    var nowDateTime = myDate.getFullYear();

    nowDateTime = nowDateTime + ((myDate.getMonth() + 1) < 10 ? "-0" + (myDate.getMonth() + 1) : "-" + (myDate.getMonth() + 1));

    nowDateTime = nowDateTime + (myDate.getDate() < 10 ? "-0" + myDate.getDate() : "-" + myDate.getDate());

    alert(nowDateTime);

</script>
