Custom CSS feature to inject custom JavaScript

[bentael]

ok so, it turns out $('body').on('action:ajaxifying') no longer works, I think it got replaced by action:ajaxify.end and it's on the window instead of the body. However, don't take my word for it yet, track that thread.

Assuming, i am right, you should be able to do that

edit: @planner That should work

</style>

<!-- gooogle ads -->
<script async defer src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
<ins class="adsbygoogle" style="display:block" data-ad-client="ca-pub-8aa076493813069" data-ad-slot="8248656285" data-ad-format="auto"></ins>

<script>
   // global _paq
    var _paq = _paq || [];
    _paq.push(["setCookieDomain", "*.linuxisi.com"]);
    _paq.push(["enableLinkTracking"]);
    _paq.push(["setTrackerUrl", ("https:" == document.location.protocol) ? "https" : "http") + "://linise.com/analyz/piwik.php"]);
    _paq.push(["setSiteId", "1"]);
</script>

<!-- then inject the piwic script, the old fashioned way, instead of writing the script tag -->
<script async defer src="//linise.com/analyz/piwik.js"></script>

<script>
$(function() {
    $(window).on('action:ajaxify.end', function(e, data) {
            (adsbygoogle = window.adsbygoogle || []).push({});

             // according to the piwik documentation, http://developer.piwik.org/api-reference/tracking-javascript, i should be to trigger page view like that
            _paq.push(["setDocumentTitle", document.domain + "/" + document.title]); // I set the document title every time, because it may have changed
            _paq.push(["trackPageView"]);
    });
});
</script>
<style>

You do not have to have all of your javascript in the footer, it's true that it helps a teeny tiny bit with page performance, since scripts execution is usually synchronous, (but using the html5 async and defer remedies that a bit for new browsers) anyways trust me, you will never feel the difference for small scripts like these.

@bentael

Thanks, I'll try it out later today

@julian so how is it going with the work of @psychobunny ? It would be an extremely useful feature.

@DennisSun Widget system is in NodeBB, starting v0.4.1 (or maybe v0.4.2)...

[DennisSun]

@julian Hi, I can see widget system in the dashboard, but there is no "javascript widget" within it. My version is v0.4.3.

[frissdiegurke]

@DennisSun The widget is called "HTML", just add a javascript-tag

[DennisSun]

@frissdiegurke well , I tried to involve javascript code in the html widget. But it didn't work. I can't even see the whole homepage after that.

[frissdiegurke]

@DennisSun Any errors on console?

this example works fine for me:

<script type="text/javascript">
  console.log('hello world!');
</script>

[DennisSun]

@frissdiegurke no error showed in log.

here is what I added:
<script type="text/javascript">
var _bdhmProtocol = (("https:" == document.location.protocol) ? " https://" : " http://");
document.write(unescape("%3Cscript src='" + _bdhmProtocol + "hm.baidu.com/h.js%3F0da233db09b6a0886cd3f9d1a52e64d8' type='text/javascript'%3E%3C/script%3E"));
</script>

The analytics code form baidu.com

[frissdiegurke]

yes, document.write replaces the whole site use sth like

<script src='https://hm.baidu.com/h.js?0da233db09b6a0886cd3f9d1a52e64d8' type='text/javascript'></script>

this seems to be what the script is supposed to do (or http:// if you don't use TLS).

[bentael]

@frissdiegurke when using document.write you can avoid replacing the whole site, but it cannot be loaded asynchronously aka injected (as it needs to execute immediately on DOM build), which is most likely the case on most NodeBB pages

@DennisSun if you want to have a dynamic the protocol, or maybe that string at the end, use something like

<script type="text/javascript">
(function() {

   var something = '0da233db09b6a0886cd3f9d1a52e64d8'; // or could be dynamically generated, I don't know

   // build your script tag 
   var script = document.createElement('script'); 
   script.type = 'text/javascript'; // that's useless, browsers ignore it, but whateves 
   script.async = true;
   script.src = ('https:' == document.location.protocol ? 'https://' : 'http://') + 'hm.baidu.com/h.js?' + something;

   // google analytics does that, this will find this actually script (unless loaded asynchronously, in that case it would find the last script tag on the page)
   // it should work in either case
   // var thisScriptTag = document.getElementsByTagName('script')[0]; 
   // thisScriptTag.parentNode.insertBefore(script, s);

   // or you can just append it to the head
     var head = document.getElementsByTagName('head')[0];
     head.appendChild(script);
})();

</script>
