从 kotlin 访问 js 变量

Question

I have two files: a.js and b.kt.

In a.js I have a variable

var x = 'something'

Then I need to access this variable in my kotlin file, like

var y = x

y.doStuff()

I tried var y = String.asDynamic().x and external but it didn't work.

So how can I get this variable in kotlin file?

Answer 1

You should convert window (the JS global scope object) to a dynamic and then access your property on that.

var thing = "hello";

fun main() {
    console.log(window.asDynamic().thing.unsafeCast<String>())
}
