Jquery remove string

Question

I am trying to remove some string from a string in Jquery but it doesnt work and my variable still looks the same.

var classes = $("body").attr('class');
alert('.side-nav' + classes);
classes = classes.replace('.side-navblog parent-  page- how-it-works-','');
$(".side-nav" + classes).css("display","block");

When I alert classes after it has been replaces, there is still .side-navblog parent- page- how-it-works- in the string which I do not want.

also the class attribute value may not have . so '.side-navblog parent- page- how-it-works-' should be 'side-navblog parent- page- how-it-works-' — Arun P Johny

classes = classes.replace('.side-navblog parent- page- how-it-works-','');
                                                      ^^ double space here

or try a regex

classes = classes.match(/how-it-works-([^$\s]*)/)[1]

Try regular expression,

classes = classes.replace(/.side-navblog|parent-|page-|how-it-works-/g, '');

What I can figure out from your comment is you have put to spaces just before 'page-'. Other than it should work fine.

classes = classes.replace('blog parent- page- how-it-works-','');
