Javascript: access to an object's member by name
<p>I have an object called <code>themesData</code>:</p>

<pre><code>var themesData = {}
themesData.a = { key: "value" }; themesData.b = { key: "another value"};
</code></pre>

<p>...and I want to access one of the members by its name. I get a string which contains either "a" or "b" and I want to get the appropriate member's value.</p>

<p>I'd be happy to get some help on that.</p>
