Question

I would like to know how to select elements using variables. What I tought would work was:

var class = "help-hu" // this value can change to "help-en" and "help-de" as well
$("."+class).fadeIn('slow');

But it doesn’t work. Any workaround?

Answer 1

If you check your browser console you will see this:

Uncaught SyntaxError: Unexpected reserved word

That means that you don’t have to use this kind of words because they are reserved!

You can try another one and use the same logic like this…

Example:

var clazz = 'help-hu';
$('.' + clazz).fadeIn('slow');

This will work without problems.
