一、js将日期格式转化为YYYY-MM-DD HH:MM:SS

Date.prototype.Format = function (fmt) { 
        var o = {
            "M+": this.getMonth() + 1, //月份 
            "d+": this.getDate(), //日 
            "h+": this.getHours(), //小时 
            "m+": this.getMinutes(), //分 
            "s+": this.getSeconds() //秒 
        };
        if (/(y+)/.test(fmt)){ //根据y的长度来截取年
    	fmt = fmt.replace(RegExp.$1, (this.getFullYear() + "").substr(4 - RegExp.$1.length));
        }
        for (var k in o){
    	if (new RegExp("(" + k + ")").test(fmt)) fmt = fmt.replace(RegExp.$1, (RegExp.$1.length == 1) ? (o[k]) : (("00" + o[k]).substr(("" + o[k]).length)));
        }
        return fmt;
    }
    // 调用： 
    var time1 = new Date().Format("yyyy-MM-dd");
    var time2 = new Date(1469281964000).Format("yyyy-MM-dd hh:mm:ss");

获取当前日期：

getCurrentDate() {
            var date = new Date();
            var seperator1 = "-";
            var year = date.getFullYear();
            var month = date.getMonth() + 1;
            var strDate = date.getDate();
            if (month >= 1 && month <= 9) {
              month = "0" + month;
            }
            if (strDate >= 0 && strDate <= 9) {
              strDate = "0" + strDate;
            }
            var currentdate = year + seperator1 + month + seperator1 + strDate;
            return currentdate;
        },
    
    
    //2018-12-1
