Date Picker

[floodster]

Hi,
Haven't posted for a while so please bear with me. I have a date picker which I sourced from http://www.nsftools.com/tips/DatePickerTest.htm & it works really well.
I've now been asked if there is anyway to exclude the user from selecting the current month or make it default to 4 weeks ahead?? I have looked at the source code & am by no means a javascript expert .
Could you please take a look & see what lines I need to change in order to achieve my goal??

I have attached the code in a zip file as I couldn't include it in this post
thanks,
john.

function refreshDatePicker(dateFieldName, year, month, day)
{
  // if no arguments are passed, use today's date; otherwise, month and year
  // are required (if a day is passed, it will be highlighted later)
  var thisDay = new Date();
 
  if ((month >= 0) && (year > 0)) {
    thisDay = new Date(year, month+1, 1);
  } else {
    day = thisDay.getDate();
    thisDay.setDate(1);
  }

Fang,
This works for the initial datepicker but if they choose a date of say '18/08/2008' & then decide to change this it then loads the month of September & there is no way of going back to August!!!

Anymore help??

Thanks.

In function drawDatePicker

refreshDatePicker(targetDateField.name, dt.getFullYear(), dt.getMonth()+1, dt.getDate());

Fang,

This increases the month each time by 1 & they can still go back & choose the month I want to be excluded.

eg.
If I want to exclude July, then this code will open the calender up in August, but they can still use the arrows to go back to July.

function getButtonCode(dateFieldName, dateVal, adjust, label)
{
  var DateToday=new Date();
  adjust = ( (dateVal.getMonth () + adjust)< (DateToday.getMonth()+1) )? 0 : adjust;
  var newMonth = (dateVal.getMonth () + adjust) % 12;
  //alert(dateVal.getMonth() + adjust+":"+newMonth)
  var newYear = dateVal.getFullYear() + parseInt((dateVal.getMonth() + adjust) / 12);
  if (newMonth < 0) {
    newMonth += 12;
    newYear += -1;
  }
 
  return "<button class='dpButton' onClick='refreshDatePicker(\"" + dateFieldName + "\", " + newYear + ", " + newMonth + ");'>" + label + "</button>";
}
