Listen to javascript events from Dart -

is there way in dart listen events javascript libraries?

for example jqrangeslider http://ghusse.github.io/jqrangeslider/ package emits uservaluechanged event when releases slider.

is easy listen event in dart via js/js.dart package?

would love see examples of listener in dart listens events javascript library.

thanks js package can deal js code. here dart version of following javascript code snippet :

$("#slider").bind("valueschanged", function(e, data){   console.log("will executed"); }); 

in dart :

js.scoped((){   js.context.jquery("#slider").bind("valueschanged", new js.callback.many((e, data) {     print("will executed");   })); }); 

note use jquery instead of $ because have issue dart2js otherwise (see issue 2265).

basically, when use callback functions in js, have use js.callback.many or js.callback.once wrap callback. see managing callback lifetimes more details.
