导读：//计算时间 var sendTime =this . props . obj .send_time; console . log ( sendTime ); //当前时间 var nowTime = ( new Date ()). valueOf (); console . log ( nowTime ); //差值 var date3 = nowTime - sendTime ; console . log ( date3 ); //天 var d

//计算时间

console . log ( sendTime );

//当前时间
var nowTime = ( new Date ()). valueOf ();

//差值
var date3 = nowTime - sendTime ;

console . log ( date3 );

//天
var days = Math . floor ( date3 / ( 24 * 3600 * 1000 ))
//时
var leave1 = date3 % ( 24 * 3600 * 1000 )

//分
var leave2 = leave1 % ( 3600 * 1000 )
var minutes = Math . floor ( leave2 / ( 60 * 1000 ))

//秒
var leave3 = leave2 % ( 60 * 1000 )
var seconds = Math . round ( leave3 / 1000 )
