[Coding Questions] what is the best way to load a file into a div that contains Java Script (lemmy.world)

Hello Everyone,

The issue: I have created a page that loads two other pages into div's at the press of a button, and then removes them on another press

Both these pages contain JavaScript. On one of the pages, the JavaScript fires when the page is loaded to fill out values pulled from a database.

The pages are loaded using a simple Ajax call, that puts the contents in the div.

The problem: obviously loading pages this way means I can't use 'document.load' to fire the JavaScript. I'm also finding that none of the scripts are loaded either.

I have a solution that can load the JavaScript after completion of the document.load, but for some reason it's not detecting the global variables with the initial Json data in it.

Both pages work individually.

The question:

  1. How do I get this to work?
  2. Is there a better (preferably non-iframe) way of doing this?
  3. Why, when the JavaScript is loaded manually, is it seeing the global Json values as 'not yet defined'?

Happy to offer any other information needed.

Thanks in advance

For those that find this question is asking something that they are also struggling with, the answer was the 'embed' tag

MDN link

You will need to place the element into a structural holder (eg div), and remove and recreate the element in JavaScript to get it to vanish and reappear if you want it to reload on show.

Pages loaded in this way do not inherit CSS theming, except background colour (if no background colour set). It does pick up @media settings, but only from the browser. This is intended behaviour.

Ultimately, to get the full functionality, I am going to have to redesign these items to be part of a single page, loading the data in piecemeal. However, this fix gets me a functional way of achieving something I need quicker than a redesign.

Thanks,

-BX
