内置函数data时间格式转换

function getDateString(date) {

var year = date.getFullYear();

var month = date.getMonth() + 1;

var day = date.getDate(); // 当月的几号

var hour = date.getHours();

var min = date.getMinutes();

var sec = date.getSeconds();

// if(month<10){

// month = "0"+month;

// }else {

// month = month;

// }

month = month < 10 ? "0" + month : month;

day = day < 10 ? "0" + day : day;

hour = hour < 10 ? ‘0‘ + hour : hour;

min = min < 10 ? "0" + min : min;

sec = sec < 10 ? "0" + sec : sec;

var str = year + "-" + month + "-" + day + " " + hour + ":" + min + ":" + sec;

console.log(str);

}

var date = new Date();

getDateString(date);
