Question

I have 2 dates and I one to check if one date comes before another one.
I know you have to parse the date to a JS date object and then check it with milliseconds.

But the problem is, in my database dateTimes are stored like this.

10-mei-2012 09:36

So my question is how can I compare two of these dates and check that date 1 comes before date2? Oh and for the record, I am also using jquery to get these values.

var dateB = $('#DATUM_BEGIN').val();
var dateE = $('#DATUM_EINDE').val();

kind regards

Here’s a function found while googling that converts MySQL DATETIME to a JS Object

function mysqlTimeStampToDate(timestamp) {
  var regex=/^([0-9]{2,4})-([0-1][0-9])-([0-3][0-9]) (?:([0-2][0-9]):([0-5][0-9]):([0-5][0-9]))?$/;
  var parts=timestamp.replace(regex,"$1 $2 $3 $4 $5 $6").split(' ');
  return new Date(parts[0],parts[1]-1,parts[2],parts[3],parts[4],parts[5]);
}

Here’s one example of how to use it:

$(function(){
  var dateB = mysqlTimeStampToDate($('#DATUM_BEGIN').val());
  var dateE = mysqlTimeStampToDate($('#DATUM_EINDE').val());

  if(dateB < dateE){
    // dateB is older
  } else {
    // dateB is newer
  }
});
