MVc 5 - validation german date with unobtrusiv js - a simple approach - asp.net-mvc-5

Question

The question: How get the unobtrusiv validation of a german date running in MVC?
Because I can't find a running example of using globalize 1.x with MVC 5 to validate a german date I needed two days to get it running.
The problems are the order of the js-files, getting the cldr-data and putting it all together in an way it can be reused.
In the answer I will show my current solution.

Answer 1

In this zip-file (https://www.dropbox.com/sh/75dx6alck7itwia/AABFkcgOQVc1bUXFE_jYfR_da?dl=0) you find all files you need.
It includes
an short todo.txt (de and en)
the cldr-data (jsons) in sub-directories
a custom HTML-Helper-class wich writes the needed HTML/js-Scripts to the view.
It seems, that rendering by the helper not allways works. So if there are problems with that, copy the code to every (edit / new) view.
<script src="~/Scripts/jquery.validate.js"></script>
<script src="~/Scripts/jquery.validate.unobtrusive.js"></script>
<script src="~/Scripts/cldr.js"></script>
<script src="~/Scripts/cldr/event.js"></script>
<script src="~/Scripts/cldr/supplemental.js"></script>
<script src="~/Scripts/cldr/unresolved.js"></script>
<script src="~/Scripts/globalize.js"></script>
<script src="~/Scripts/globalize/currency.js"></script>
<script src="~/Scripts/globalize/number.js"></script>
<script src="~/Scripts/globalize/date.js"></script>
<script src="~/Scripts/globalize/plural.js"></script>
<script src="~/Scripts/globalize/relative-time.js"></script>
<script src="~/Scripts/globalize/unit.js"></script>
<script src="~/Scripts/jquery.validate.globalize.js"></script>
<script>
$(document).ready(function () {
// Use $.getJSON instead of $.get if your server is not configured to return the
// right MIME type for .json files.
$.when(
$.get("/Scripts/cldr/main/de/ca-gregorian.json"),
$.get("/Scripts/cldr/main/de/numbers.json"),
$.get("/Scripts/cldr/supplemental/likelySubtags.json"),
$.get("/Scripts/cldr/supplemental/timeData.json"),
$.get("/Scripts/cldr/supplemental/weekData.json")
).then(function () {
// Normalize $.get results, we only need the JSON, not the request statuses.
return [].slice.apply(arguments, [0]).map(function (result) {
return result[0];
});
}).then(Globalize.load)
.then(function () {
Globalize.locale("de-DE");
});
});
</script>
I hope it helps.
This solution based on the answer to MVC 5 - can not get globalisation running.
