MVC Render JSONResult as a Literal

I have a JsonResult action in my MVC project...

public JsonResult GetData(string term) {
    List<String> data = repo.GetData(term).ToList();
    return Json(data, JsonRequestBehavior.AllowGet);
}

This powers a jquery autocomplete lookup but as there is only 30 values in the database, I think that this is not efficent use of database resources...

<script type="text/javascript">
    jQuery(document).ready(function ($) {
        $("input#MyTextBox").autocomplete({
            source: '<%: Url.Action("GetDate","Controller") %>',
                delay: 1,
                minChars: 2
            }
        );
    });
</script>

I would like to generate something simlar to this...

<script>
  $(document).ready(function() {
    $("input#MyTextBox").autocomplete({
    source: ["my","list","of","values"]
});
  });
</script>

I am missing something here as this should be simple. Is there a way that I can change the url.action to something that will render the JSON almost like a PartialView ?

Also, is this a good solution to the problem or can someone show me a better way?

2 points:

  1. Yes, there is a way to render JSON easier:

    <script type="text/javascript">
jQuery(document).ready(function ($) {
    $("input#MyTextBox").autocomplete({
        source: <%: Html.Raw(Json.Encode(Model.AutocompleteSourceFromDb)) %>,
            delay: 1,
            minChars: 2
        }
    );
});
</script>

  2. From database usage perspective this doesn't change a thing. You still rendering the whole JSON on page render and not querying database on autocomplete.
