Using sections in Editor/Display templates
I want to keep all of my JavaScript code in one section; just before the closing body tag in my master layout page and just wondering the best to go about it, MVC style.
For example, if I create a DisplayTemplate\DateTime.cshtml file which uses jQuery UI's DateTime Picker than I would embed the JavaScript directly into that template but then it will render mid-page.
In my normal views I can just use @section JavaScript { //js here } and then @RenderSection("JavaScript", false) in my master layout but this doesn't seem to work in display/editor templates - any ideas?

You could proceed with a conjunction of two helpers:
public static class HtmlExtensions
{
public static MvcHtmlString Script(this HtmlHelper htmlHelper, Func<object, HelperResult> template)
{
htmlHelper.ViewContext.HttpContext.Items["_script_" + Guid.NewGuid()] = template;
return MvcHtmlString.Empty;
}
public static IHtmlString RenderScripts(this HtmlHelper htmlHelper)
{
foreach (object key in htmlHelper.ViewContext.HttpContext.Items.Keys)
{
if (key.ToString().StartsWith("_script_"))
{
var template = htmlHelper.ViewContext.HttpContext.Items[key] as Func<object, HelperResult>;
if (template != null)
{
htmlHelper.ViewContext.Writer.Write(template(null));
}
}
}
return MvcHtmlString.Empty;
}
}
and then in your _Layout.cshtml:
<body>
...
@Html.RenderScripts()
</body>
and somewhere in some template:
@Html.Script(
@<script src="@Url.Content("~/Scripts/jquery-1.4.4.min.js")" type="text/javascript"></script>
)
