How to Append Raw HTML and JavaScript to a Div?

Estimated read time 2 min read

To append raw HTML and JavaScript to a div element using JavaScript, you can create a new element and set its innerHTML property to the desired HTML and JavaScript code, then append it to the div element. Here’s an example:

// Get the div element to which the HTML and JavaScript will be appended
const myDiv = document.getElementById('my-div');

// Create a new script element with some JavaScript code
const scriptElement = document.createElement('script');
scriptElement.innerHTML = 'console.log("Hello from JavaScript!");';

// Create a new HTML element with some HTML code
const htmlElement = document.createElement('p');
htmlElement.innerHTML = 'This is some <strong>HTML</strong> code.';

// Append the new elements to the div
myDiv.appendChild(scriptElement);
myDiv.appendChild(htmlElement);

In this example, getElementById('my-div') selects the div element with the ID of “my-div”. The first two lines create new elements: a script element with some JavaScript code, and a p element with some HTML code. The innerHTML property is used to set the content of these elements.

The last two lines use appendChild() to append the new elements to the div. The order in which you append the elements will determine their position within the div.

Note that appending raw HTML and JavaScript to a page can be a security risk if the content is not sanitized or validated, especially if the content is user-generated. It’s important to validate or sanitize any user input before appending it to the page to avoid security vulnerabilities such as cross-site scripting (XSS) attacks.
