So here is the setup:
I have two jquery datepickers, inside a jquery tab, inside a jquery modal dialog window:

```
\---/\---/\---/_______________
/                            /
\                            \
/  DATEPICKER1               /
\                            \
/  DATEPICKER2               /
\                            \
/                            /
\                            \
/____________________________/

```

The first datepicker functions normally, but when I try to click a date in the second datepicker it simply activates the first one. Did you follow that? :)

So to sum up, clicking a date in datepicker2 activates datepicker1.

I have no idea why this is happening - they have different ids and names, as outlined below.

To create the datepickers I'm just using:

```
$(function() {
    $("#datepicker1").datepicker();
    $("#datepicker2").datepicker();
});

```

The fields are simply:

```
<input type="text" id="datepicker1" name="datepicker1" value="" />
<input type="text" id="datepicker2" name="datepicker2" value="" />

```

I'm using jQuery v1.9.0 and jQueryui v1.10.0.

Any thoughts on this? As a caveat, I am unable to post actual code due to restrictions from my employer, but I can answer most questions if you need any clarification. Any and all help would be greatly appreciated!!

**UPDATE:**
It looks like the behavior described below was addressed in another stackoverflow question here:  

[Prevent jQuery UI dialog from setting focus to first textbox](https://stackoverflow.com/questions/1202079/prevent-jquery-ui-dialog-from-setting-focus-to-first-textbox)

Apologies for the "duplicate" question - if I had known this was the problem I would have figured it out quickly!!!

Well, the resolution is very simple, and perhaps someone can enlighten me as to why it works this way because I'm a bit clueless at the moment.

Here's what I did:  

I added another two text input fields to the form (they were needed) and reordered the layout so that one of those new input fields was the "first" element (in the top-left corner), like so:

```
\---/\---/\---/_______________
/                            /
\                            \
/  TEXTFIELD1   DATEPICKER1  /
\                            \
/  TEXTFIELD2   DATEPICKER2  /
\                            \
/                            /
\                            \
/____________________________/

```

Suddenly the problem has vanished! However, I notice an interesting behavior:  

When I select a date in EITHER datepicker, the cursor then immediately jumps back to the first text field.
So if this were happening when I had the datepickers with no text fields, that behavior would mean that the cursor would immediately have jumped back to the first datepicker which could have cause the issue I was having.

Now, as to WHY it works this way I have no idea. I tried setting the tabindex parameters for the various textfields/datepickers but that didn't change the behavior.

Anyway, I appreciate the input from everyone who chimed in - this was a weird problem, but I'll never forget how to fix it now. Thanks everyone for your help!!
Just to preface, I am a backend database programmer so know little about JavaScript so looked to find this post with the exact same question. Gleaning from what I read above and comparing to my existing code, I modified my JavaScript so that it works and thought I would share it.

The only caveat was that my existing forms with single date selectors no longer worked so I had to add a bit to handle those and all seem fine now. In this case, the database fields are actually a Unix timestamp so the form gets processed when submitted with the two fields converted as needed but for clarity, I did not include that code here.

```
$(document).ready(function(){ 
       $( "#StartDate" ).datepicker({   
                                altField: '#datepicker',
                                altFormat: 'yy-mm-dd',
                                dateFormat: 'D M d, yy', 
                                firstDay: 1,
      onClose: function( selectedDate ) {  
        $( "#StartDate" ).datepicker( "option", "minDate", selectedDate );  
      }  
    });  
    $( "#EndDate" ).datepicker({
                                altField: '#datepicker',
                                altFormat: 'yy-mm-dd',
                                dateFormat: 'D M d, yy', 
                                firstDay: 1,
      onClose: function( selectedDate ) {
        $( "#EndDate" ).datepicker( "option", "maxDate", selectedDate );
      }
    }); 
        $( "#datepicker" ).datepicker({
                                altField: '#datepicker',
                                altFormat: 'yy-mm-dd',
                                dateFormat: 'D M d, yy', 
                                firstDay: 1,
      onClose: function( selectedDate ) {
        $( "#datepicker" ).datepicker( "option", "maxDate", selectedDate );
      }
    });     
  });
