引入js

<script src="http://cdn.bootcss.com/underscore.js/1.8.3/underscore-min.js"></script>

创建自定义函数

_.template.formatdate = function (stamp) {
    var d = new Date(stamp), // or d = new Date(date)
            fragments = [
                d.getFullYear(),
                d.getMonth() + 1,
                d.getDate()
            ];
    return fragments.join('-');
};

调用

<%=_.template.formatdate(data)%>
