网上找了个JS的Date转换函数,发现很多网站都有类似的代码,找不到真正的出处,无法贴上来源地址;

还有一个Date转换的npm类库,详情查看这里

Date.prototype.format = function(format) {
	    /*
	     * eg:format="yyyy-MM-dd hh:mm:ss";
	     */
	    var o = {
	        "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()
	    }

	    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;
}
