Globalize library script for validating dates in MVC3 applications

I've been struggling to integrate a javascript datepicker into my MVC3, EF4 project with the UK date format (dd/mm/yyyy). After hours of research, I decided to try using the 'globalize' library scripts based on this helpful link.

However, when testing, I encountered an error:

Uncaught TypeError: Cannot read property 'methods' of undefined
in the javascript code, specifically from the $.validator.methods.date line. My knowledge of javascript is limited, and looking at examples using the 'globalize' library did not provide any explanation for this issue.

Below, I have included the relevant code snippet from my view:

<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery-1.5.1.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery-1.5.1.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery-ui-1.8.11.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery-ui-1.8.11.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.globalize/globalize.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.globalize/cultures/globalize.culture.en-GB.js")" type="text/javascript"></script>

<link href="../../Content/themes/base/jquery.ui.all.css" rel="stylesheet" type="text/css" />
<script type="text/javascript">
    Globalize.culture("en-GB");
    $.validator.methods.date = function (value, element) { return this.optional(element) || Globalize.parseDate(value); }
</script>

<script type="text/javascript">
    $(document).ready(function () {
        $('.date').datepicker({ dateFormat: "dd/mm/yy" });
    });
</script>

//SNIP

<div class="editor-field">
    @Html.TextBox("Expires", Model.Expires, new { @class = "date" })
    @Html.ValidationMessageFor(model => model.Expires)
</div>

If anyone could offer assistance in resolving this issue, it would be greatly appreciated.

Thank you.

It's been a while since I last used the Globalize library, and I think it might be too much for what you need. If all you require is the date value in en-GB, then the following Javascript/jQuery code should do the trick (you can also check out this fiddle):

<input type="text" class="date" placeholder="en-gb datepicker" />
<button id="btnGetVal">Get Value</button>

<script type="text/javascript">
$(document).ready(function () {
    /* Make sure to set the date format when initializing the datepicker */
    $('.date').datepicker({ dateFormat: "dd/mm/yy" });
    /* Create an event handler for the button click function */
    $('#btnGetVal').on('click', function() {
       /* Event handler */
       var targetValue = $('.date').val();
       alert(targetValue);
    });
});
</script>

I've tested this with jQuery 2.1.0 and jQuery UI 1.10.4 - you may need to update your NuGet packages for both. If you're using an old version of jQuery, it might be because you need to support IE8 or are using an older version of MVC.

On another note, ensure all your Javascript code is initialized within the document.ready() function so that all functions can be accessed upon load (otherwise, your Globalize code may not be accessible when initializing the datepicker().
