jQuery Datepicker - Programatically Limit Second Datepicker

I've recently been using the following piece of code to limit my 2nd Date picker (end date) so that it does not precede the da开发者_开发技巧te of the 1st Date picker.

$("#datepicker").datepicker({
 minDate: +5, 
 maxDate: '+1M +10D',  
 onSelect: function(dateText, inst){
           var the_date = dateText;
           $("#datepicker2").datepicker('option', 'minDate', the_date);

 }
 });
 $("#datepicker2").datepicker({

    maxDate: '+1M +10D', 
    onSelect: function(dateText, inst){

    }                       
});

However, lately, I wanted to format my datepickers using:

dateFormat: 'yy-mm-dd'

But now, the 2nd datepicker actually allows the user to pick a date 1 day before.

For example, if the user picks the 1st date: 2010-04-03, when the 2nd Datepicker pops up, they are able to pick 2010-04-02 (1 day before their first selected date).

I do not want the user to be able to pick a date that was before their first selected day.

Any ideas why this isn't working after I added in the "dateFormat"?

option minDate expect a date object not a string object.. you can however specify the format and do the conversion as follow:

$(document).ready(function() {  //Runs when tab is loaded

var dateFormat = "yy-mm-dd";

$("#datepicker").datepicker({
 minDate: +5, 
 dateFormat:dateFormat,
 maxDate: '+1M +10D',  
 onSelect: function(dateText, inst){
           var the_date = $.datepicker.parseDate(dateFormat,dateText);
           $("#datepicker2").datepicker('option', 'minDate', the_date)
 }
 });
 $("#datepicker2").datepicker({

    maxDate: '+1M +10D', 
    dateFormat:dateFormat,
    onSelect: function(dateText, inst){

    }                       
});


});

You could alternatively do this

       onSelect: function(){
           $("#datepicker2").datepicker('option', 'minDate', $(this).val());
       }
