Question

This code works:

$(contentDiv).fadeIn("slow");

This does not:

var elementName = 'contentDiv';
$(elementName).fadeIn("slow");

No fade effect appears.

I’m about to feel like an idiot with this solution I know but I can’t work it out.

Answer 1

You need to specify whether ‘contentDiv’ is a class or id

var elementName = '.contentDiv';
$(elementName).fadeIn("slow");

OR

var elementName = '#contentDiv';
$(elementName).fadeIn("slow");
