【JavaScript】时间转时间戳，时间戳转时间的常用方法

时间戳转时间

方法一：

使用：

timeto(152425542,"ymd-hms");

//获取时间戳转当前时间 年月日，时分秒
function timeto(date,type) {
    var seperator1 = "-";
    var seperator2 = ":";
    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;
    }
    if(type == "ym"){
        // 转年月
        var currentdate = date.getFullYear() + seperator1 + month;
    }else if(type == "ymd"){
        // 转年月日
        var currentdate = date.getFullYear() + seperator1 + month + seperator1 + strDate;
    }else if(type == "ymd-hms"){
        //转年月日 时分秒
        var currentdate = date.getFullYear() + seperator1 + month + seperator1 + strDate
                + " " + date.getHours() + seperator2 + date.getMinutes()
                + seperator2 + date.getSeconds();
    }else if(type == "hms"){
        //转时分秒
        var currentdate =date.getHours() + seperator2 + date.getMinutes() + seperator2 + date.getSeconds();
    }
    return currentdate;
}

方法二：

//时间戳转时间 yy-mm-dd  getTimes(time)//时间戳转时间 yy-mm-dd hh:mm:ss  getTime(time)

//时间戳转时间
function updatetime(a){
	return a<10?"0"+a:a;
}
Date.prototype.toLocaleString = function() {
    return this.getFullYear() + "-" + updatetime((this.getMonth() + 1)) + "-" + updatetime(this.getDate()) + " " + updatetime(this.getHours()) + ":" + updatetime(this.getMinutes()) + ":" + updatetime(this.getSeconds());
};
Date.prototype.toLocaleStrings = function() {
    return this.getFullYear() + "-" + updatetime((this.getMonth() + 1)) + "-" + updatetime(this.getDate());
};
Date.prototype.toLocaleStringm = function() {
    return this.getFullYear() + "-" + updatetime((this.getMonth() + 1));
};
function getTime(time){
	if(isUndefined(time)){
		return ;
	}else{
		var unixTimestamp = new Date( time ) ;
		commonTime = unixTimestamp.toLocaleString();
		return commonTime;
	}
	
}//
function getTimes(time){
	if(isUndefined(time)){
		return ;
	}else{
		var unixTimestamp = new Date( time ) ;
		commonTime = unixTimestamp.toLocaleStrings();
		return commonTime;
	}
	
}
function getTimem(time){
	if(isUndefined(time)){
		return ;
	}else{
		var unixTimestamp = new Date( time ) ;
		commonTime = unixTimestamp.toLocaleStringm();
		return commonTime;
	}
}

时间转时间戳

方法一：

//转换毫秒
function getTimesByDate(datestr,type){
	//type(0-yyyy-MM-dd,1-yyyy-MM-dd h:m:s);
	if(isUndefined(datestr)){return ""};
	var dp="-";
	var date_ar=datestr.split(dp);

	var y=Number(date_ar[0]);
	var m=Number(date_ar[1]);
	var d=Number(date_ar[2]);

	var theDate=new Date();
	theDate.setFullYear(y,m-1,d);

	return theDate.getTime();
}
