JS时间戳和时间之间转换

var date = new Date(); //时间对象
var str = date.getTime(); //转换成时间戳

function getDate(tm){
var tt=new Date(tm).toLocaleString();
return tt;
}

function getDate(tm){
var tt=new Date(tm).toLocaleString().replace(/\//g, "-");
return tt;
}

function getDate(tm){
var date = new Date(tm); //转换成时间对象，这就简单了
var year = date.getFullYear();  //获取年
...
return tt;
}

 //备注

function add0(m){return m<10?'0'+m:m };
function getDate(shijianchuo) {
//shijianchuo是整数，否则要parseInt转换
var time = new Date(shijianchuo);
var y = time.getFullYear();
var m = time.getMonth()+1;
var d = time.getDate();
var h = time.getHours();
var mm = time.getMinutes();
var s = time.getSeconds();
return y+'-'+add0(m)+'-'+add0(d)+' '+add0(h)+':'+add0(mm)+':'+add0(s);
};
