What's the best and most secure way to take a fragment of html from one document and add it to another html document with Javascript?
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I've researched this a fair bit, but the advice is a bit confusing since it either seems out of date or possibly not the most secure way of handling things.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?
You're viewing a single thread.
You're trying to reinvent the wheel. This has been solved by modern JS frameworks. Learning one of them will get you a safer better site than trying to "Frankenstein" your own with little experience.
I disagree. The fundamentals of the web specs are more important than ever, and many projects don't even need a frontend framework.
