How do I add type=”text/javascript” to a script tag when using System.Web.Optimization

I have the following

bundles.Add(new ScriptBundle("~/bundles/scripts/common").Include(

Which generates
<script src="/bundles/scripts/common?v=9O0Yi3fV_GWpGyJQ_QYURiOYy6SEmxUQtkUVN4GXo2U1"></script>

When rendered with
    <asp:PlaceHolder ID="PlaceHolderJs" runat="server">                
            <%: Scripts.Render("~/bundles/scripts/common") %>

Which is not valid HTML as its missing type=”text/javascript”. How do I make the BundleCollection output this element in the script tag?


Thank you for visiting the Q&A section on Magenaut. Please note that all the answers may not help you solve the issue immediately. So please treat them as advisements. If you found the post helpful (or not), leave a comment & I’ll get back to you as soon as possible.

Method 1

One way is to change how you render your scripts:



<script src="@BundleTable.Bundles.ResolveBundleUrl("~/bundles/scripts/common")" type="text/javascript"></script>

Or depending on how you are implementing bundling, you may need:
<script src="@Microsoft.Web.Optimization.BundleTable.Bundles.ResolveBundleUrl("~/bundles/scripts/common")" type="text/javascript"></script>

Or for web forms:
<script src="<%= Microsoft.Web.Optimization.BundleTable.Bundles.ResolveBundleUrl("~/bundles/scripts/common")%>" type="text/javascript"></script>

Although if there is a way to do it using @Script.Render I’d like to see it.

UPDATE: in response to your comments, as specified in this SO answer, in the pre-release version of System.Web.Optimization, there is an option called RenderFormat that will let you do this as well… but I think the stuff above is easier to read for this particular case.

Method 2

I believe the answer marked is not correct for type="text/css", it is correct for JavaScript (maybe the question title is misleading?). For CSS files you should use


and not @Scripts.Render(...). The reason is that minification is done, and only @Styles.Render(...) knows about Cascading Stylesheet syntax, @Scripts.Render(...) is specialized for JavaScript minification.

Method 3

I have resolved it like that

>      bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
>                             "~/Scripts/node_modules/jquery/dist/jquery.min.js"));

i think you need to replace ~/bundles/scripts/common with ~/bundles/jquery

Method 4

I have resolved it like that

    new ScriptBundle("~/bundles/jquery").Include(

I think you need to replace ~/bundles/scripts/common with ~/bundles/jquery
