Research direction

Reproduce the two behavior examples in Hyperscript 0.9.12, then trace how behavior init handles an omitted optional parameter and the clickElement reference. Done means install alertMe() defaults the click target to me while the explicit clickElement: me case continues to work.

Written by the indexing model from the issue text.

Description

I'm using Hyperscript 0.9.12 and attempting to do something similar to what the Draggable example does. Default to "me" if a specific click target is not passed in.

The init block does not work.

<script type="text/hyperscript">
    behavior alertMe(clickElement)
        init
            if no clickElement set the clickElement to me
        end

        on click from clickElement
            call alert('behavior is working!')
        end
    end
</script>

<!-- Works: -->
<i _="install alertMe(clickElement: me)">click me</i>

<!-- Does not work: -->
<i _="install alertMe()">click me</i>
