Hi @dominikh , without the "for {}" loop your channel receives only once, was this by intention ?

@shurcooL : you are right, I meant putting the for loop in a goroutine, see further down

I have no problem in understanding the following program: The receiving goroutine continues active since the click event gets hooked up to the dom and thereby the main loop continues running.
This is not the case in my playground example, no dom is involved.

This is at least my understanding for such a use case where the dom is involved, and from what I know Dart make the same assumptions. In my first playground example no dom is involved, so I need to know for what reasons gopherjs continues with active goroutines.

package main
//html page imports jquery.js and has a #someButtonId Button
import "github.com/gopherjs/gopherjs/js"
var jQuery = js.Global.Get("jQuery")

func main() {

    ch := make(chan int)
    go func() {
        for {
            print("prepared to receive...")
            println(<-ch)
        }
    }()
    jQuery.New("#someButtonId").Call("on", "click", func(this *js.Object) {
        print("sending now...")
        ch <- 1
    })
}

Goroutine runs forever #229
