MVC3 Razor removes script tags from HtmlString

I have a method that adds javascript to the end of partial views if it's an ajax request. My problem though is that when the script is returned, the script tags 开发者_如何学Gohave been removed and the function I want to execute is written in plain text.

if (httpContext.Request.IsAjaxRequest())
        {
            script = "MyNamespace.globals.initFunctions.push(function() { " + script + " });";
            return new HtmlString(@"<script type=""text/javascript"">" + script + "</script>");
        }

So, instead of getting the desired result of

<script type="text/javascript">MyNamespace.globals.initFunctions.push(function() { MyNamespace.init(); });</script>

I get MyNamespace.globals.initFunctions.push(function() { MyNamespace.init(); }); in plain text.

What could be the reason?

Edit:

Trying it with Html.Raw() did not help. While the script string does contain the script tags, they are still removed when rendered.

    @{
    string script = ViewUtilities.AddScript("MyNamespace.init();", this.ViewContext.HttpContext);
}

    @Html.Raw(script);

Edit 2:

Now I've tried writing it all in the view like this,

<script type="text/javascript">
    MyNamespace.globals.initFunctions.push(function() { MyNamespace.init(); });
</script>

and it still removes the tags around the script and renders it as plain text. I don't know where to go from here...

When I exam the response with Firebug it looks fine but looking at the html it's not.

The HTML is being encoded which happens auto-magically with ASP.NET MVC.

Using @Html.Raw("htmlstring") should give you the raw HTML value of the string without stripping the tags.

You want to use @Html.Raw(whatever function you call)

I think you also probably want to return return MvcHtmlString.Create(fullscript);

If you convert this to an HtmlHelper method, it will work. Change your ViewUtilities class as follows:

public static class ViewUtilities
{
    public static MvcHtmlString AddScript(this HtmlHelper htmlHelper, string script)
    {
        if (htmlHelper.ViewContext.HttpContext.Request.IsAjaxRequest())
            return new MvcHtmlString(@"<script type=""text/javascript"">" + script + "</script>");
        return new MvcHtmlString("");
    }
}

Then, in the web.config file in the Views folder (and in any Views folders in any Areas), add the following to the namespaces list in the <pages pageBaseType="System.Web.Mvc.WebViewPage"> element:

<add namespace="{namespace where ViewUtilities class is located}"/>

Finally, in your view:

@Html.AddScript("MyNamespace.init();")
