You need to reference the jQuery UI in the header since that isn't loaded by Qualtrics (your first and third lines). You shouldn't need to load jQuery itself (your second line).

Thank you very much for your answer.



But if I open the Javascript console of my browser and drop "jQuery.ui.version", I get "1.11.1" as feedback.



I don't understand that.

@Ingo,



I think jQuery or jQueryUI is logging the jQueryUI version. Maybe because it is older or doesn't match the current jQuery version. You could load jQuery UI 1.12:

```

<link href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css" rel="stylesheet" />

<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>

```

When I change the language of the survey, this no longer works. Any idea why?

It would be helpful if you described what exactly you mean by "this no longer works" (i.e., what happens, what does the screen look like, etc.). Have you read the localization documentation and implemented it?

I have no idea what the localization means. When I change language from English to French, the date picker does not come up. It is just a blank text box. Same thing happens when I turn it back to English.



Here is the current code I am using:



In header:



<link href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css" rel="stylesheet" />

<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>



In Javascript:



Qualtrics.SurveyEngine.addOnReady(function()

{

jQuery("#"+this.questionId+" .InputText").each(function(index){

jQuery(this).datepicker({

yearRange: '2008:2010',

dateFormat : 'yy-mm-dd',

defaultDate: '2008-01-01',

changeMonth: true,

changeYear: true

})

});

});
