scala.js

When I use scala.js to write scala code to generate javascript, I found it difficult sometimes to wrap the 3rd-party javascript code into scala objects. Is there anyway to embed some javascript code directly? e.g. as strings? No, there isn't, on purpose. How would identifiers in the "embedded" JavaScript code bind to identifiers in the surrounding Scala.js code, for example? That would never make any sense. The ugly workaround: js.eval You can "embed" JavaScript code as a parameter to the js.eval function, obviously. import scala.scalajs.js def foo(x: Int): Unit = js.eval("console.error('hello

In idiomatic JavaScript it's common to have a function accept an "options object" as the last parameter. This is where you'd usually put all the option/seldom-used parameters, e.g. jQuery.ajax({ url: "http://www.example.com/foo", success: function() { .. } }) The current documentation for Scala.JS recommands using a Scala trait to represent the options object, but that leads to a problem when you have to create the options since you cannot pass an anonymous class into JavaScript code. How can such option objects be created from Scala code? gzm0 We recommend the following (if you chose to
