jQuery 1.7.0 is out!

…and I like the new .on() and .off() API for setting up events.

I wrote some code that uses it, just for practice.

$.fn.tree = function(data) {
  var $el = $(this),
      html = [];
  
  function renderNode(node) {
    if (typeof node === "object") {
      html.push("<ul>");
      for (var key in node) {
        if (node.hasOwnProperty(key)) {
          html.push("<li><strong>" + key + ": </strong>");
          html.push(typeof node[key] == "object" ? renderNode(node[key]) : node[key]);
          html.push("</li>");
        }
      }
      html.push("</ul>");
    }
  }
  
  renderNode(data);
  $el.html(html.join(""));
  
  $el.on('click', 'strong', function() {
    $(this).closest('li').find('ul').toggle(200);
  });
};

$("<div>").appendTo("body").tree({
  name: {
    first: "Benjamin",
    last: "Atkin"
  },
  location: {
    city: "Boulder",
    state: "CO"
  },
  accounts: {
    social: {
      twitter: "http://twitter.com/benatkin",
      facebook: "http://facebook.com/atkin",
      gplus: "http://gplus.to/benatkin",
      identica: "http://identi.ca/benatkin",
      rstatus: "http://rstat.us/bat"
    },
    creative: {
      github: "http://github.com/benatkin",
      blog: "http://benatkin.com/"
    }
  }
});

Nothing too fancy.
