I want to add Scrollspy support to the nav-menu, for that I have to add extra attributes data-spy="scroll" data-target=".navbar"
to the body
tag.
Can I do that pragmatically without touching theme files?
One way would be to:-
Edit header.php
And add those attributes to the body.
Alternative (without editing theme files) way would be to create a plugin which adds a js that adds those attributes to body. Something like this:-
$("body").attr( { data-spy:"scroll", data-target:".navbar" } );
EDIT After viewing Sevi's answers. The most suitable way is
function wp_body_classes( $classes )
{
$classes[] = '" spy="scroll" data-target=".navbar';
return $classes;
}
add_filter( 'body_class','wp_body_classes', 999 );
