Incorporate the elements of HTML, CSS, Javascript, and Jquery to import the contents from one HTML file and display it within the div of another HTML file

$(function(){   $.get("header.html", function(data){
    $("#header").html(data);   }); });

In the near future, I will need to accomplish this task in Java. For now, I am using jQuery, a JavaScript extension, but any format that achieves the desired outcome is acceptable.

I have 2 files: header.html

<!-- Header -->
<div class="row navigationBar">

  <!-- Company Logo -->
  <div class="col-2">
...
      </nav>
    </div>
  </div>
</div>
<!-- Header End -->

and the webpage webpage.html

<!DOCTYPE html>
<html lang="en" dir="ltr">
  <head>
    <meta charset="utf-8">
    <title></title>
  </head>
  <body>
    <div id="header"></div>
  </body>
</html>

The goal is to load header.html and set it into the element with id=("header") within webpage.html

Currently, the only functioning code snippet is

$("#header").html("")
. With this syntax, I can successfully add content such as:

<p>Hello World</p>

However, I encounter issues when trying to include the loaded items from header.html.

--NEW CONTENT WITH ANSWER IN PROGRESS--

Despite the existing answers being incorrect, I have devised my own solution that should theoretically work. I just need assistance with implementing it.

Prior to res.send(/*HTML Code Here*/);, here's what I propose: A: Load the HTML file into a variable. B: Load the insertion code into another variable. C: Replace parts of A with B. D: res.send(A);

This method has proven successful for me in Java, and occasionally in jQuery. However, I struggle to find the correct syntax to execute this in vanilla JavaScript.

If you can provide the necessary code to implement this concept, I will mark your response as the answer.

Note A looks something like:

<!DOCTYPE html>
<html lang="en" dir="ltr">
  <head>
    <meta charset="utf-8">
    <title></title>
  </head>
  <body>
    <!--InsertionPoint-->
  </body>
</html>

B resembles:

<p>Hello World</p>

In this example, the replacement keyword would be an empty string.

The resulting output sent in the res.send() function would be:

<!DOCTYPE html>
    <html lang="en" dir="ltr">
      <head>
        <meta charset="utf-8">
        <title></title>
      </head>
      <body>
        <p>Hello World</p>
      </body>
    </html>

Answer №1

give this a shot

<script>
document.getElementById("header").innerHTML='<object type="text/html" data="header.html"></object>';
</script>




Modified for different approach
I stumbled upon this solution on a coding website. I've tested it out and believe it could resolve your issue. https://www.w3schools.com/howto/howto_html_include.asp

<script>
    includeHTML();

    function includeHTML() {
        var z, i, elmnt, file, xhttp;

        z = document.getElementsByTagName("*");
        for (i = 0; i < z.length; i++) {
            elmnt = z[i];
            
            file = elmnt.getAttribute("w3-include-html");
            if (file) {
                xhttp = new XMLHttpRequest();
                xhttp.onreadystatechange = function () {
                    if (this.readyState == 4) {
                        if (this.status == 200) {
                            elmnt.innerHTML = this.responseText;
                        }
                        if (this.status == 404) {
                            elmnt.innerHTML = "Page not found.";
                        }
                       
                        elmnt.removeAttribute("w3-include-html");
                        includeHTML();
                    }
                }
                xhttp.open("GET", file, true);
                xhttp.send();
                
                return;
            }
        }
    };
</script>

add something similar to this in your body tag

<div w3-include-html="header.html"></div>

Just remember to include the w3-include-html attribute for it to work, and you can place your stylesheet at the beginning of webpage.html
