I wrote this code to check if a text box is empty. If it is I put the current date into it with a score and loop over the six boxes.Once it fills the boxes it will then loop over checking the dates and it finds the oldest and overrides it with the new value.I feel what I have done here may be a bit crude and or long winded, this there a better way I could have done this?<input type=textbox id=bank1 value=19990112 class=bank /> 1<br><input type=textbox id=bank2 value=19980112 class=bank /> 2<br><input type=textbox id=bank3 value=19970112 class=bank /> 3<br><input type=textbox id=bank4 value=19960112 class=bank /> 4<br><input type=textbox id=bank5 value=19950112 class=bank /> 5<br><input type=textbox id=bank6 value=19940112 class=bank /> 6<br><input type=button value=Click Me id=btn />var idAndValues = {};var Time = [];var oldest = ;var formatDateMili = ;var ids = ;var m = false;var now = new Date();var a = now.getFullYear();var b = now.getMonth();var c =now.getDate();var FullDateNow = a.toString() + 0+b.toString() + c.toString();$('#btn').click(function() {  $('.bank').each(function() {    if ($(this).val() != ) {      var StoredDate = $(this).val();      var formatDateMili = DateStringSort(StoredDate).getTime();      Time.push(formatDateMili);      ids = $(this).attr('id');      idAndValues[ids] = formatDateMili;    } //end if     if ($(this).val() === ) {      $(this).val(19980214 + _ + score);      m = true;      return false;    } else {      m = false;    }  }); // end loop   if (m != true) {    oldest = Math.min.apply(null, Time);    for (var key in idAndValues) {      if (idAndValues.hasOwnProperty(key)) {        //   alert(idAndValues[key]+  key checking +  oldest checking + oldest);        if (idAndValues[key] === oldest) {          $('#' + key).val(FullDateNow + _ + score);          Time = [];        }        //   alert(key +  ->  + idAndValues[key]);      }    }  }});function DateStringSort(Stored) {  var StoredDayTrim = Stored.substring(6, 8);  var StoredmonthTrim = Stored.substring(4, 6);  var StoredYearTrim = Stored.substring(0, 4);  var FormatDate = new Date(StoredYearTrim, StoredmonthTrim, StoredDayTrim);  return FormatDate;}here is a fiddle
