dwr 日期时间转换

/*时间格式化 http://www.naoqiu.com*/
Date.prototype.format = function (format) {
    var o = {
        "M+": this.getMonth() + 1,
        "d+": this.getDate(),
        "H+": this.getHours(),
        "m+": this.getMinutes(),
        "s+": this.getSeconds(),
        "q+": Math.floor((this.getMonth() + 3) / 3),
        "S": this.getMilliseconds()
    }
    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;
}

今天遇到一个问题，需要向后台提交Date型数据。就要将 字符串 转换为javascript 的Date对象:如

<input type="text" id="d" value="2014-04-01 00:00:00">
<script>
var _d=$("#d").val();
var _dat=new Date($.trim(_d).replace("-","/"));
</script>
