Riot Parents

This is a simple Riot.js mixin which helps with the issue of

this.parent.parent.someproperty

and replaces it with

this.parents(2).someproperty

with parents	with parent
this.parents(0)	this.parent
this.parents(1)	this.parent.parent
this.parents(2)	this.parent.parent.parent
this.parents(3)	this.parent.parent.parent.parent

I realise that accessing deep ancestors like this makes your components perhaps more coupled that they should be. But sometimes it's nice to be able to drop elements into yielding components and still be able to easily communitcate with them.

Installing

npm install riot-parents

Usage

To add it to all tags

var parents = require('riot-parents')
riot.mixin(parents)

To add it to specific tags, load it the same way, but assign it a name

var parents = require('riot-parents')
riot.mixin("parents",parents)

Then you can use it within specific tags to access parent tags. eg.

<mylogin>
  <modal>
    <loginform>
      <formrow label="Username">
        <input oninput="{parents(2).handleInput}" name="username" type="text" />
      </div>
      <formrow label="Password">
        <label>Password</label>
        <input oninput="{parents(2).handleInput}" name="password" type="password" />
     </formrow>
    </loginform>
  </modal>
  
  <script>
    this.mixin('parents') // <-- don't need this if you've installed it globally
    this.handleInput = function(e){
      this[e.target.name] = e.target.value
    }
  </script> 
</mylogin>
