Custom Elements

[Luigi vargas aquino]

Hi folks!

I want to rewrite legacy Custom Elements of one of my Rails app in Opal, like this https://gist.github.com/007lva/1265b149c70428cf23704dd527fac140. I can't find any of example of how to work with native DOM elements like HTMLSpanElement. Also I would like to know which is the "idiomatic" way to do something like this:

SharedCount = Object.create(HTMLSpanElement.prototype)


Thanks!

Hi Luigi,

I think you can do:

require 'native'

# bridge HTMLSpanElement into opal-world, and then:

class HTMLSpanElement < `HTMLSpanElement`

end

class SharedCount < HTMLSpanElement

end

$$[:document].registerElement 'shared-count', SharedCount.JS['$$alloc']
