I want the following call to render only if such call wasn't already declared in a parent view.
@Scripts.Render("~/Scripts/jQuery")
What's the best way to do so?

1generally you should design your bundles so they dont have overlaps, id suggest having one bundle for the main page and one for the child viewDaniel Powell– Daniel Powell2013-02-20 01:56:27 +00:00Commented Feb 20, 2013 at 1:56

additionaly if you are loading jquery related libraries these should be added at the end of the page in most cases, so the master page/layout is the best place to do this.Daniel Powell– Daniel Powell2013-02-20 01:57:17 +00:00Commented Feb 20, 2013 at 1:57

This already is at the layout page, it's however an area local layout. It needs to detect if the parent layout already defines these things. I need the check at runtime. In short, yes I'm aware there're workarounds, but I want this to behave exactly as I described it. Is there a way to do so out of the box? I can run custom code if I have to, but prefer to work with the framework.Alwyn– Alwyn2013-02-20 02:07:31 +00:00Commented Feb 20, 2013 at 2:07

Here is one way:
<script>
if (!window.jQuery) {
document.write('<script src="@BundleTable.Bundles.ResolveBundleUrl("~/Scripts/jQuery")">\x3C/script>');
}
</script>
This is essentially the same logic used when one includes jQuery from a CDN, and then has a local reference fallback if the CDN delivery failed.

Yes this seems like one possible solution. Thank you!
