How can I use js eval to return a value?
<p>I need to evaluate a custom function passed from the server as a string. It's all part of a complicated json I get, but anyway, I seem to be needing something along the lines:</p>

<pre><code>var customJSfromServer = "return 2+2+2;"
var evalValue = eval(customJSfromServer);
alert(evalValue) ;// should be "6";
</code></pre>

<p>Obviously this is not working as I expected. Any way I can achieve this ?</p>
