使用 System.Web.Optimization 时如何将 type="text/javascript" 添加到脚本标记

Question

I have the following

bundles.Add(new ScriptBundle("~/bundles/scripts/common").Include(
                  "~/Scripts/jquery.validationEngine.js",
                  "~/Scripts/common.js"));

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") %>
    </asp:PlaceHolder>

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

Answer 1

One way is to change how you render your scripts:

From:

@Scripts.Render("~/bundles/scripts/common")

To:

<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.

Answer 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

@Styles.Render("~/bundles/styles/common")

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.

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

Answer 4

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
