Hi, In my MVC 2 site, I have an html helper, that I use to add javascripts for my pages. In my master page I have the main javascripts I want to include, and then in the aspx pages, I include page specific javascripts.
So for example, my Site.Master has something like this:
....
<head>
<%=html.renderScripts() %>
</head>
...
//core scripts for main page
<%html.AddScript("/scripts/jquery.js") %>
<%html.AddScript("/scripts/myLib.js") %>
....
Then in the child aspx page, I may also want to include other scripts.
...
//the page specific script I want to use
<% html.AddScript("/scripts/register.aspx.js") %>
...
So when the full page gets rendered the javascript files are all collected and rendered in the head by sitemaster placeholder function RenderScripts. This works fine.
Now with MVC 3 and razor view engine, they layout pages behave differently, because now my page level javascripts are not rendered/included. Now all I see the LayoutMaster contents.
How do I get the solution wo workwith MVC 3 and the razor view engine. (The helper has already been re-written to return a HTMLString ;-))
For reference: my MasterLayout looks like this:
...
...
<head>
@{
Html.AddJavaScript("/Scripts/jQuery.js");
Html.AddJavaScript("/Scripts/myLib.js");
}
//Render scripts
@html.RenderScripts()
</head>
....
and the child page looks like this:
@{
Layout = "~/Views/Shared/MasterLayout.cshtml";
ViewBag.Title = "Child Page";
Html.AddJavaScript("/Scripts/register.aspx.js");
}
....
<div>some html </div>
Thanks for your help.
Edit = Just to explain, if this question is not clear enough.
When producing a "page" I collect all the javascript files the designers want to use, by using the html.addJavascript("filename.js") and store these in a dictionary - (1) stops people adding duplicate js files - then finally when the page is ready to render, I write out all the javascript files neatly in the header. (2) - this helper helps keep JS in one place, and prevents designers from adding javascript files all over the place. This used to work fine with Master/SiteMaster Pages in mvc 2. but how can I achieve this with razor?
