JavaScript / Extjs - 计算时间戳的小时数

Question

I have this time stamp format for each car in my map:

2012-12-11T03:51:43+03:00

I want to extract the number of hours from it according to current time.

I don't know how to parse this string then compare it to current time.

Any Idea ?

Answer 1

something like:

var
  d1 = new Date('2012-12-11T03:51:43+03:00'),
  d2 = new Date;

console.log(
  (d2 - d1) / 3600000
);

Answer 2

You need to first fix the timestamp for other browsers than Chrome

javascript date.parse difference in chrome and other browsers

DEMO

var noOffset = function(s) {
  var day= s.slice(0,-5).split(/\D/).map(function(itm){
    return parseInt(itm, 10) || 0;
  });
  day[1]-= 1;
  day= new Date(Date.UTC.apply(Date, day));  
  var offsetString = s.slice(-5)
  var offset = parseInt(offsetString,10)/100;
  if (offsetString.slice(0,1)=="+") offset*=-1;
  day.setHours(day.getHours()+offset);
  return day.getTime();
}
alert(parseInt((new Date().getTime()-noOffset(yourTimeStamp))/3600000))
