make the base of URL constructor configurable?

[hesxenon]

I have a rather niche use case (and will probably deploy a fork for now) where I'm trying to use HTMX out of an iframe with [href=about:srcdoc]. So when HTMX tries to construct any URL at all it's expanded to new URL("the path", "about:srcdoc") which obviously isn't a valid url.

Would it be possible to add a config option to specify the base parameter?

Like

urlBase?: undefined | string | "root"

where "root" would have the special meaning of using the root windows url.

Hey, as it's a niche usecase, I would recommend either:

• Adding a htmx:configRequest event listener in your JS to modify the request's URL through event.detail.path (just realized that this event's documentation doesn't mention path though... But it's here!)
• Creating a custom extension to handle that (that would use the same mechanism as described in my first point, this would simply allow you to configure it per-element with for example the said URL prefix in an attribute value)

Hope this helps!

Hey, yes it helped, thank you :) not sure if I should close this though, I can still see a use case for this 🤔

the latest version 2.0.5 now has this:

    const url = new URL(path, location.protocol !== 'about:' ? location.href : window.origin)

This hopefully handles about:srcdoc use cases
