scala.js call external js function

I want to try using scala.js on a SalesForce project.

SalesForce automatically injects the Visualforce.remoting.Manager.invokeAction(...) function to enable querying data and doing dml.

How can I call this function from scala.js?

You should be able to call any exposed javascript method from scala-js using 

scala.scalajs.js.eval(x: String)

Example for calling a bootbox modal:

 import scala.scalajs.js.annotation.JSExportTopLevel
 import scala.scalajs.js

 @JSExportTopLevel("myCallBack")
 protected def confirmCallback() = // do stuff

 def askAQuestion(): Unit = {
    js.eval("bootbox.confirm(\"Your question goes here.\", function(result) { if (result == true) { myCallBack(); }});")
 }

Of course for this to work you have to include the javascript libary in your project.

Since this is a quite messy solution, you might consider writing your own facade.

In the crudest sense, you could just invoke it directly from global scope using js.Dynamic, something like:

js.Dynamic.global.Visualforce.remoting.Manager.invokeAction(...)

That works for a one-off, but if you're going to be working more with this Manager, I'd probably recommend creating a Scala.js facade for the Manager, and assigning the Manager object to that -- it'll probably result in better code in the long run.
