Question

I am trying to query for a button which has a predefined value.

If the query value is as follows, it works fine:

_v = "Button1";

But as soon as the query value is:

_v = "Button 1"; // with spaces
_v = "Button / Button / Button"; // or with slashes

the following query fails:

$('.club[value=' + _v + ']').addClass('active');

and i get the following error:

Uncaught Syntax error, unrecognized expression: [value=Button 1]

How do I have to change the query so that it doesn’t fail anymore?

Answer 1

You need to wrap the value with double quotes

$('.club[value="' + _v + '"]').addClass('active');
