custom attributes

[aeosynth]

this may be out of scope, but i'd like custom attributes, so i can implement my own version of declarative event mapping

i'm not sure what that means. can you provide an example of what you'd like to work?

[aeosynth]

a custom on-click attribute: ```

pulled from a polymer example

[rafaelw]

you're not being clear. what do you want to work which doesn't work right now.

You can put whatever attribute you want on elements. The parser will not stop you.

i would like to define a custom attribute, and when the parser sees this attribute, my custom code is run, similar to what the parser does with {{ }} syntax

[rafaelw]

Yeah, unfortunately this is outside the scope of MDV. It sounds like you'd like to mix in behavior to an element based on the presence of an attribute. I suggest using mutation observers and the mutation summary library for this. There's no good way to observe an attribute pattern (e.g. "on-*"), but if you enumerate the attributes you support, it will work.

See MutationSummary: https://code.google.com/p/mutation-summary/

Isn't this similar to decorators (and another source)?

Only thing that could get in the way:

The script is run once when the decorator element is inserted into the document
