    I am using Flask btw
  • r
    https://htmx.org/headers/hx-trigger/ > If you want to pass details along with the event, you can move to JSON for the value of the trigger: > > HX-Trigger: {"showMessage":"Here Is A Message"}
  • l
    I think I did that
  • l
    I see the response in Chrome
  • l
    output = { "showMessage": "Here Is A Message" } resp = jsonify(output) resp.headers['HX-Trigger-After-Swap'] = 'timer_started' return resp
  • r
    the docs suggests putting the json in the header itself
  • r
    resp.headers['HX-Trigger-After-Swap'] = output
  • r
    like that
  • r
    change "showMessage" to the name of your event and you should be good to go
  • l
    ah ok let me check
  • l
    That causes: "SyntaxError: Unexpected token ' in JSON at position 1"
  • r
    Can you see the header in response in Chrome?
  • l
    To be clear, I changed my event name to showMessage 🙂
  • r
    oh
  • r
    why is it single-quoted?
  • r
    JSON only supports ", not '
  • l
    it's the jsonify of flask
  • l
    wait, I'll just send back the json string
  • l
    it work 😮
  • l
    thanks a lot 🙂
  • l
    very strange that flask.jsonify returns the ' though ...
  • l
    that call for some investigation.
  • r
    it's actually extremely weird, considering that when JSON was in the response, it used the correct quotes. But I have zero experience with flask, so, little help from me there
  • l
    No problem. You helped me a lot! Thanks!!

    You are not alone: > Critical thinker. You rarely take things as a given without first getting the facts. When colleagues say “because that’s the way it’ done,” or a vendor promises the solution to all you problems, you smell a challenge. The Pragramatic Programmer. Young people should read old books (it was re-edited in 2020 though).

    Hey, just stumbled upon htmx via the HN article today and seems to be a cool project. I'm currently using Hotwired with Node.js backend and liking it, however sometimes feeling if it could be a bit simpler. Probably will take htmx for a spin in a new project as I'm already rewriting the SPA stuff into Hotwired and don't wanna restart the process 😄 Anyways, thanks for creating this!

    > The young boys should read old books Why only the boys? Or did you mean young people?
  • f
    yes, sorry! (edited)

    QQ: Is there a way (preferably an event) to catch boosted links. I am having to add 
    _=on click send loading to #sys_loader
    to show a global loading overlay, when a boosted link is clicked, is there a way I can do this universally
  • c
    maybe have a quick read of https://htmx.org/docs/#indicators
