How do I properly register javascript blocks in an ASP.NET MVC 2 (RTM) Editor template?
The specific scenario I'm in is that I want to use Dynarch JSCal2 DateTimePicker for my standard datetime picker, but this question is in general to any reusable javascript package. I have my template working properly now but it has my JS and CSS includes in my master page and I would rather only include these things if I actually need them:
<link rel="stylesheet" type="text/css" href="../../Content/JSCal2-1.7/jscal2.css" />
<link rel="stylesheet" type="text/css" href="../../Content/JSCal2-1.7/border-radius.css" />
<script type="text/javascript" src="../../Scripts/JSCal2-1.7/jscal2.js"></script>
<script type="text/javascript" src="../../Scripts/JSCal2-1.7/lang/en.js"></script>
So obviously I could just put these lines into my template, but then if I have a screen that has 5 DateTimePickers, then this content would be duplicated 5 times which wouldn't be ideal. Anyways, I still want my View's Template to trigger this code being put into the <head> of my page.
While it is completely unrelated to my asking this question, I thought I'd share my template on here (so far) in case it's useful in any way:
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<DateTime>" %>
<%= Html.TextBoxFor(model => Model) %>
<input type="button" id="<%= ViewData.TemplateInfo.GetFullHtmlFieldId("cal-trigger") %>" value="..." />
<script type="text/javascript">
var <%= ViewData.TemplateInfo.GetFullHtmlFieldId("cal") %> = Calendar.setup({
trigger : "<%= ViewData.TemplateInfo.GetFullHtmlFieldId(string.Empty) %>",
inputField : "<%= ViewData.TemplateInfo.GetFullHtmlFieldId(string.Empty) %>",
onSelect : function() { this.hide(); },
showTime : 12,
selectionType : Calendar.SEL_SINGLE,
dateFormat : '%o/%e/%Y %l:%M %P'
});
</script>
