JS获取当前日期 YYYY-MM-DD hh-mm-ss的示例代码

//获取当前时间（中国标准时间）
var myDate = new Date();
//日期时间截取
myDate.getYear();        //获取当前年份(2位)
myDate.getFullYear();    //获取完整的年份(4位)
myDate.getMonth();       //获取当前月份()
myDate.getDate();        //获取当前日()
myDate.getDay();         //获取当前星期X()
myDate.getTime();        //获取当前时间()
myDate.getHours();       //获取当前小时数()
myDate.getMinutes();     //获取当前分钟数()
myDate.getSeconds();     //获取当前秒数()
myDate.getMilliseconds();    //获取当前毫秒数(0-999)
myDate.toLocaleDateString();     //获取当前日期
myDate.toLocaleString( );        //获取日期与时间
myDate.toLocaleTimeString();     //获取当前时间
myDate.toDateString ()           //转字符串
myDate.getTime()                 //转时间戳
