Question

HTML counterpart to PHP's include for JavaScript components

I am searching for a Javascript alternative to a method I have been using in PHP. Specifically, I want to streamline the basic setup of my pages:

<!DOCTYPE html>
        <html lang="en">
            <head>
                <meta charset="utf-8">
                <meta name="viewport" content="width=device-width initial-scale=1.0">
                <meta http-equiv="X-UA-Compatible" content="ie=edge">

...by placing this code in a php file like 'doc_start.php' and then starting every page on my site with...

<?php require_once('/path/to/doc_start.php); ?>

Now, I have a project that is purely HTML and JS (no PHP) and I want a similar way to avoid repeating common HTML elements. I need more functionality than just the basics, such as importing JQuery on every page, linking to a common stylesheet, etc. While it was simple in PHP, I am still learning how to do this efficiently in JS.

I have looked into HTML5 includes, but have not found anything that fits my specific needs.

If you want to include content from other pages in your current document, you can do so by using a link tag.

Here's an example...

<head>
  <link rel="import" href="/path/to/imports/content.html">
</head>

By doing this, you can easily include HTML, CSS, or JavaScript files into your page without having to duplicate the code on each page.

When it comes to programming, Javascript and PHP serve different purposes. However, if you find yourself needing to avoid repeating certain elements, there is a simple solution:

First, store the HTML elements that you do not want to repeat as a string. Then, utilize the .innerHTML property to add these elements.

The .innerHTML property essentially holds the markup of an element as a string.

For instance, consider the following <div>:

<div class="example"> <br> Hello there this is a test! </div>

If we were to use .innerHTML on this example:

console.log(document.querySelector(".example").innerHTML);

The output would be "

<br> Hello there this is a test!

".

To append to the existing content with .innerHTML, simply use the += operator. Therefore, adding something within the body can be achieved as follows:

var something = "some HTML";
document.body.innerHTML += something;

We hope this explanation has provided you with the guidance you were seeking!

If you need to retrieve data from a file, there are two main methods you can use:

fetch('file.html')
   .then(response => response.text())
   .then(data => {
     // Process the contents of the file here
     console.log(data);
   })
   .catch(error => {
     console.log('An error occurred:', error);
   });

Alternatively, you can use XMLHttpRequest:

var xhr = new XMLHttpRequest();
xhr.open('GET', 'file.html', true);
xhr.onreadystatechange = function() {
   if (xhr.readyState === 4 && xhr.status === 200) {
     // Process the contents of the file here
     console.log(xhr.responseText);
   }
};
xhr.send();

Both of these methods serve the same purposes. I hope this clarifies things for you!
