I would like to know if it is possible to display multiple specific categories.
For example, if I would like to display only categories #1 and #2 but not the others, how I could do that ?
Those errors usually mean websockets are not proxied correctly, make sure your nginx setup is correct. If you are using cloudflare you need to disable acceleration. They don't support websockets on smaller plans.
I imagine if href is missing, this.href would be undefined, no? smile
No. 😛
I was surprised that it's been an empty string that got checked instead of undefined too, but it seems I'm to adapted to jQuery ^^
This is because you use the DOM-element rather than jQuery to get the href:
document.createElement('a').href === ''
$('<a></a>').attr('href') === undefined
