I’m not new to programming, but I am somewhat new to web development and I’m trying to figure out the most preferred way of taking a standalone header from one html document and adding it to other html documents without code duplication. If possible I want to do this with Javascript so I can learn with more basic tools before expanding further.
I’ve researched this a fair bit, but the advice is a bit confusing since it either seems out of date or possibly not the most secure way of handling things. Is there a preferred way of doing something like this?
It’s technically possible to do that, but it’s kind of a pain. I asked about server-side JS because the server is where I’d do something like this as my first choice.
If you really want to do it in the browser, you could use an AJAX call to get the html from the server, then use DOM functions to find that snippet by id. (Or just put them in separate html files and save yourself the pain of those DOM functions.)
I found this for you. https://gomakethings.com/getting-html-with-fetch-in-vanilla-js/ I think it actually has most of what you want to do.
Thanks for the link and the advice. I wasn’t sure how to approach something like this since it’s handled a bit differently with the software development I’m used to, but I think I’m starting to get a clearer idea of why things work the way they do on the web side.
