Question

MVC + RegisterClientScriptInclude / RegisterClientScriptBlock

Answer 1

+3 A:

I've done this with an extension method on the HtmlHelper Html.RegisterJavascript( string ). I create a key, "__javascript__", in the ViewData dictionary. This holds a dictionary of javascript entries keyed off of a digest of the javascript (to prevent duplicates).

The problem is that these registrations happen after the header has been processed, so script tags have to go at the end of the file. Before the body end tag, I have a call to Html.RenderJavascript(); (my method).

I couldn't find a better way, but I have to imagine a more clever solution is possible.

Answer 2

+3 A:

You can use Spark view engine, that has "once" attribute for this purpose. E.g.

<content name="MasterPageHead">
  <script once="CustomScriptUniqueIdName" ... />
</content>

When used in a view or a partial, script (or this can be any other tag, e.g. div) will only be included once in the master page section called MasterPageHead (which you can place in <head>).

Not sure if this will be helpful for you, but you asked for a MVC solution, not WebForms solution.
