ASP.Net: Do I need to add javascript source of _ValidationScriptsPartial.cshtml to _layout.cshtml?

Question

In ASP.Net 5 project I have a file named _ValidationScriptsPartial.cshtml by default:

<environment names="Development">     <script src="~/lib/jquery-validation/jquery.validate.js"></script>     <script src="~/lib/jquery-validation-unobtrusive/jquery.validate.unobtrusive.js"></script> </environment> <environment names="Staging,Production">     <script src="//ajax.aspnetcdn.com/ajax/jquery.validation/1.11.1/jquery.validate.min.js"             asp-fallback-src="~/lib/jquery-validation/jquery.validate.js"             asp-fallback-test="window.jquery && window.jquery.validator">     </script>     <script src="//ajax.aspnetcdn.com/ajax/mvc/5.2.3/jquery.validate.unobtrusive.min.js"             asp-fallback-src="~/lib/jquery-validation-unobtrusive/jquery.validate.unobtrusive.min.js"             asp-fallback-test="window.jquery && window.jquery.validator && window.jquery.validator.unobtrusive">     </script> </environment> 

But when I need to use jquery validation, I have to add:

<script src="~/lib/jquery-validation/jquery.validate.js"></script>         <script src="~/lib/jquery-validation-unobtrusive/jquery.validate.unobtrusive.js"></script> 

below part of _layout.cshtml:

<environment names="Development">             <script src="~/lib/jquery/dist/jquery.js"></script>             <script src="~/lib/bootstrap/dist/js/bootstrap.js"></script>             <script src="~/lib/hammer.js/hammer.js"></script>             <script src="~/lib/bootstrap-touch-carousel/dist/js/bootstrap-touch-carousel.js">            I HAVE TO ADD SCRIPT FOR JQUERY VALIDATION HERE             </script>         </environment> 

What is the purpose of _ValidationScriptsPartial.cshtml? How is this file used in the project? Please give me reference how to use this file?

Answer 1

Partial Views are meant to be used inside other views. You would not normally add the validation scripts to the _layout.cshtml since that (_layout.cshtm) is used on every page.

However, if you have a view where you need to use these scripts you just add the partial view inside the .cshtml file of your view like this:

@section Scripts {     @{await Html.RenderPartialAsync("_ValidationScriptsPartial"); } } 

If you created a standard web project with identity using VS 2015 then you can see an example of this usage in Views/Account/Register.cshtml
