How to Add HTML Using JavaScript?

Estimated read time 2 min read

To add HTML using JavaScript, you can follow these steps:

  1. Select the element where you want to add HTML content. You can use various methods like document.getElementById(), document.getElementsByClassName(), or document.querySelector() to select the element.
  2. Create the HTML content you want to add. You can create the content as a string or as a DOM element.
  3. Use the innerHTML property to add the HTML content to the selected element. For example, if you have selected an element with the ID “example”, you can add HTML content using the following code:
document.getElementById("example").innerHTML = "<h1>Hello, World!</h1>";
  1. Alternatively, you can use the appendChild() method to add a new element as a child of the selected element. For example, if you want to add a new div element to the selected element, you can use the following code:
var newDiv = document.createElement("div");
newDiv.innerHTML = "This is a new div.";

Note that it’s important to ensure that any HTML content you add using JavaScript is safe and doesn’t contain any potentially harmful code. It’s also important to consider accessibility when adding HTML content dynamically, and to ensure that the content is properly formatted and structured.
