Sending Javascript to GWT JSNI

I know how to call Javascript from GWT.But I have a javascript function that returns a string so, how could I when that function is called send it to GWT.

Hope this makes sense

Solution

  • This is how you collect strings from JSNI fn

    public static native String stringExample() /*-{ return "String1"; }-*/;

    This is how you pass a string to JSNI fn

    public static native void alert(String msg) /*-{ $wnd.alert(msg); }-*/;

    Hope this is what you were looking for.
