Add Class To Regex Jquery

I have this if( window.location.href == 'http://localhost:3000/categories') { $('#container ul #all_categories a.categories-menu').css('font-weight','bold'); } }); but

Solution 1:

You don't need a RegEx. The following method is easier, and is also easier to maintain (you don't have to change the URL in the code when moving the page to the production environment):

location.pathname.indexOf('/boards', 1) !== -1

The previous would also match /me/not/boards. If you don't want that:

var index = location.pathname.indexOf('/boards', 1);
index !== -1 && location.pathname.lastIndexOf('/', index-1) === 0

Finally, the RegEx method:

/^\/[^/]+\/boards/.test(location.pathname)

Implementation example

if( /^\/[^/]+\/boards/.test(location.pathname) ) {
         $("#container ul #all_categories a.categories-menu").css("font-weight","bold");
    }   
});
