Im trying to add a widget to the composer, I have got far enough to where I can insert the code from the tool bar, but I am not sure how to get the javascript working within it. I am assuming that I will need to add the javascript internally either as a plug-in or theme component rather than calling it from an external site, but I am not sure how to go about doing that. Is this doable within the composer?

What I am trying to is to have users insert their specific widget from the composer where all the would have to do type a number and have the toolbar wrap around it. for example if typed 112756 it would wrap the following code around it. Loading PurpleAir Widget... it would hopefully look something like this [Screen Shot 2021-10-29 at 10.51.44 AM]

Ok so it sounds like you have already figured out how to add content to the composer? (If not, referencing this example may help GitHub - discourse/discourse-gifs · GitHub - this theme component opens a modal when the button is clicked from the toolbar, and then inserts content into the composer based on clicking some content in the modal). If you’re trying to get a script to load and do something to the post content, I think this post might get you pointed in the right direction… using loadScript and decorateCooked: Difficulties in correctly adding external JavaScript - #4 by StevenTammen

You might be able to use this in some way (either directly or a forked customisation): Mentionables which uses a special character instead of a composer button.

Thanks for pointing me in the right direction, I do seem to run into another issue, it is not loading/rendering when opening the topic page that would use the script. Only after I refresh the page does it load properly, but not every time. Is this because Discourse is a Single Page Application, I’m am just trying to figure out if my knowledge of Discourse is lacking or if something that I need to program my self. Here is the current code I am using. Any direction would be greatly appreciated let loadScript = require('discourse/lib/load-script').default; api.decorateCooked($elem => { $elem.children('div[data-PAWidget]').ready(function() { $elem.children('div[data-PAWidget]').append(" Loading PurpleAir Widget... "); loadScript("https://www.purpleair.com/pa.widget.js?key=21R72LUN79CXRZ50&module=AQI&conversion=C0&average=0&layer=standard&container=PurpleAirWidget_11726_module_AQI_conversion_C0_average_0_layer_standard").then(()=>{ }) }) });

I took a crack at this and ended up with similar results. I tried to use decorateCookedElement because we’ll eventually deprecate decorateCooked api.decorateCookedElement( (element) => { element.childNodes.forEach((node) => { if (node.dataset && node.dataset.pawidget) { node.insertAdjacentHTML( "beforeend", " Loading PurpleAir Widget... " ); loadScript( `https://www.purpleair.com/pa.widget.js?key=${node.dataset.pawidget}&module=AQI&conversion=C0&average=0&layer=standard&container=PurpleAirWidget_11726_module_AQI_conversion_C0_average_0_layer_standard` ); } }); }, { id: "widget-append", onlyStream: true, afterAdopt: true } ); Slight difference here is that I passed in the key with the data attribute: This works ok for me if it’s the first time the script has been loaded. If I view a post with the script, then go back to the topic list and re-enter the topic, it does not work (until I refresh). I can see decorateCookedElement is firing each time when the relevant post is loaded, but there’s something preventing the script from working again. I’m not sure if it’s related, but I also see a Uncaught TypeError: i is null error in the console from pa.widget.js: [Screen Shot 2021-11-08 at 9.11.39 PM]

Thanks for taking a crack at it. I did notice that the script is called roughly every 90 seconds to two minutes if I leave the page open. [Screen Shot 2021-11-09 at 3.52.24 PM] So it does load eventually. Is there any documentation/posts on how/why it loads in at a later point?

Can you be a little more specific about what you’re trying to do? Are you trying to add a new toolbar button that adds content to the composer textarea? something else?
