Find element in page with class XYZ

Question

I am running a script as follows:

Galleria.run(".showcase");

The problem is when there is no element with class ".showcase" a message is rendered on the page.

How can I run this code if an element with class .showcase is found in the page?

`document.querySelector('.showcase') && Galleria.run(".showcase");` — dfsq, Jul 04 '15 at 19:24
You appear to be using some framework but haven't told us which one. This could be useful information. — , Jul 04 '15 at 19:26
