hi Anand_ : you have to require jquery explicitly
<
adambeynon>
if you are using rails, it already has it registered as a gem
<
adambeynon>
so just add a "require 'jquery'" to your opal source

HI Adambeynom, I already have require 'opal'
<
Anand_>
require 'opal_ujs'
<
Anand_>
require 'opal-jquery'
<
Anand_>
in my firebug when I do $, it does show query is loaded
<
Anand_>
it comes back with "jQuery 1.11.0(selector, context)"
<
adambeynon>
Anand_: so what is the actual error that shows up?
<
Anand_>
Hi Adam, There is no error. I am not able to get a simple jq method say element.css 'color','white' to work
<
adambeynon>
Anand_: does the selector definately find the element? try inspecting the instance which should list each dom element it finds
<
Anand_>
require 'opal'
<
Anand_>
require 'opal_ujs'
<
Anand_>
require 'opal-jquery'
<
Anand_>
elements = Element['.art']
<
Anand_>
puts 'just elements =' + elements
<
Anand_>
puts 'just elements.class =' + elements.class
<
Anand_>
elements.css 'color','white'
<
Anand_>
Document.ready? do
<
Anand_>
elements.css 'color','white'
<
adambeynon>
Anand_: you probably need to put the selector inside the ready block
<
Anand_>
no luck after I did that
<
Anand_>
I downloaded vienna and modified an opal file to see if a simi=lair method worked
<
Anand_>
My index.html seems to some how get <script data-turbolinks-track="true" src="/assets/greeter.js?body=1"></script>
<
Anand_>
<script data-turbolinks-track="true" src="/assets/application.js?body=1"></script>
<
Anand_>
not sure if having the greeter.js be loaded after application.js
<
adambeynon>
Anand_: thats just turolinks kicking in (a default rails gem)
<
adambeynon>
Im not sure why its not applying the class
<
adambeynon>
that method is working ok for me locally
<
Anand_>
Thank I will dig around
<
Anand_>
Thank you rod retaking time to help me out
<
Anand_>
Have a great day.

Hello everyone! I'm new to opal and already love it - ruby for everything!
<
tils>
I have a question - how can I set the property of an object that was created natively, like this:
<
tils>
audio = %x{ new Audio() }
<
tils>
I would like to set the src property, and got it to work like this so far:
<
tils>
%x{ #{audio}.src = "/assets/sounds/bicycle.mp3" }
<
tils>
but how can I replace the string dynamically with a ruby value?

ok, I think I found it, this works: sound = "foo.mp3"; %x{ #{audio}.src = #{sound} }
<
tils>
I was previously trying to use an interpolated string inside the %x{ } block, which didn't work

like this: %x{ #{audio}.src = "/assets/sounds/#{mode}.mp3" }

hi tils: is that working ok for you now? Native makes a nice wrapper around native objects so you can use "real" ruby code
<
adambeynon>
audio = Native(`new Audio`)
<
adambeynon>
audio.src = "..."
