copied!<p>Here's a proof-of-concept implementation for getting jQuery itself work on objects. Through an object wrapper (<code>FakeNode</code>), you can trick jQuery into using its built-in selector engine (Sizzle) on plain JavaScript objects:</p> <pre><code>function FakeNode(obj, name, parent) { this.obj = obj; this.nodeName = name; this.nodeType = name ? 1 : 9; // element or document this.parentNode = parent; } FakeNode.prototype = { documentElement: { nodeName: "fake" }, getElementsByTagName: function (tagName) { var nodes = []; for (var p in this.obj) { var node = new FakeNode(this.obj[p], p, this); if (p === tagName) { nodes.push(node); } Array.prototype.push.apply(nodes, node.getElementsByTagName(tagName)); } return nodes; } }; function $$(sel, context) { return $(sel, new FakeNode(context)); } </code></pre> <p>And the usage would be:</p> <pre><code>var obj = { foo: 1, bar: 2, child: { baz: [ 3, 4, 5 ], bar: { bar: 3 } } }; function test(selector) { document.write("Selector: " + selector + "<br>"); $$(selector, obj).each(function () { document.write("- Found: " + this.obj + "<br>"); }); } test("child baz"); test("bar"); </code></pre> <p>Giving the output:</p> <pre> Selector: child baz - Found: 3,4,5 Selector: bar - Found: 2 - Found: [object Object] - Found: 3 </pre> <p>Of course, you'd have to implement a lot more than the above to support more complex selectors.</p> <p>BTW, have you seen <a href="http://www.hugoware.net/" rel="nofollow noreferrer">jLinq</a>?</p>
