JS Date函数整理(2)

1.通过prototype为Date增加format函数，格式字符串可自由配置

<script type="text/javascript">
/**  
 * 时间对象的格式化;  
 */
Date.prototype.format = function(format) {
    /*
     * eg:format="YYYY-MM-dd hh:mm:ss";
     */
    var o = {
        "Y" :this.getYear(), // year
        "M+" :this.getMonth() + 1, // month
        "d+" :this.getDate(), // day
        "h+" :this.getHours(), // hour
        "m+" :this.getMinutes(), // minute
        "s+" :this.getSeconds(), // second
        "q+" :Math.floor((this.getMonth() + 3) / 3), // quarter
        "S" :this.getMilliseconds()    // millisecond
    }
  
    if (/(y+)/.test(format)) {
        format = format.replace(RegExp.$1, (this.getFullYear() + "").substr(4 - RegExp.$1.length));
    }
  
    for ( var k in o) {
        if (new RegExp("(" + k + ")").test(format)) {
            format = format.replace(RegExp.$1, RegExp.$1.length == 1 ? o[k]
                    : ("00" + o[k]).substr(("" + o[k]).length));
        }
    }
    return format;
}
//alert(new Date().format("Y-M-dd hh:mm:ss"));
</script>
