Custom background using "Custom Class" + "Custom CSS"?


  • @yariplus said:

    if (ajaxify.data && ajaxify.data.cid && ajaxify.data.cid === '16') {
    

    ajaxify.data.cid is actually a number, but apart from that, ta.


  • Actually I've made it more generic so I can easily add CSS to multiple categories:

    <script>
    $(window).on('action:ajaxify.contentLoaded', function(){
        if (ajaxify.data && ajaxify.data.cid){
            $('body').addClass('categoryid_'+ajaxify.data.cid);
      }
    });
    </script>
    

    Then just edit .categoryid_16{.....} in the custom CSS.

    You shouldn't need js at all, each page has a specific css class added to the body element already.

    Nevermind I see you want to change css inside topics based on category, in that case you need js.

    @PJH Ahh, nice. That definitely looks better.


  • Of course, the class needs to be removed when you're no longer in there....

    So I just figured out why the else-clause was in the original.

    Adding a one on the next start event should work I think.

    </script>
    $(window).on('action:ajaxify.contentLoaded', function(){
        if (ajaxify.data && ajaxify.data.cid){
            $('body').addClass('categoryid_'+ajaxify.data.cid);
            $(window).one('action:ajaxify.start', function(){
                $('body').removeClass('categoryid-'+ajaxify.data.cid);
            });
        }
    });
    </script>
    

  • Went with this:

    <script>
    $(window).on('action:ajaxify.contentLoaded', function(){
        $("body").removeClass (function (index, css) {
            return (css.match (/\bcategoryid_\S+/g) || []).join(' ');
        });
        if (ajaxify.data && ajaxify.data.cid){
            $('body').addClass('categoryid_'+ajaxify.data.cid);
        }
    });
    </script>

            });
        }
    });
    </script>
    

    Testing shows that works too - but is there any way the removeClass() could fail to get called even though the body retains the class? (e.g. a refresh doesn't count as not calling it, because the classes would get reset anyway.)

    @PJH Not that I know of. The only way it wouldn't fire is if ajaxify is turned off, and in that situation the classes would get reset anyway.
