JS function that returns a function in order to bind an attribute.

example.js

function markRowHidden(dataAttribute) {
  return function() {
    var tr = $(this).closest('tr');
    tr.data(dataAttribute, true);
    tr.hide();
  }
}

$("tr form.type1").on("submit", markRowHidden("attribute1"));
$("tr form.type2").on("submit", markRowHidden("attribute2"));

Re: Dom data vs js state:

If you're mutating, it's state. I like to isolate my application state in tiny js data structures The rest of the app runs as a function of those microscopic objects and the collections fetched from the server.
