javascript locals()?
39,960
<p>In python one can get a dictionary of all local and global variables in the current scope with the built-in functions locals() and globals(). Is there some equivalent way of doing this in javascript? For instance, I would like to do something like the following:</p> <pre><code>var foo = function(){ alert('foo'); ...

<p>@e-bartek, I think that window[functionName] won't work if you in some closure, and the function name is local to that closure. For example:</p> <pre><code>function foo() { var bar = function () { alert('hello world'); }; var s = 'bar'; window[s](); // this won't work } </code></pre> <p>In...

<p>@pkaeding</p> <p>Yes, you're right. <em>window[functionName]()</em> doesn't work in this case, but <em>eval</em> does. If I needed something like this, I'd create my own object to keep those functions together.</p> <pre><code>var func = {}; func.bar = ...; var s = "bar"; func[s](); </code></pre>
