How to Append HTML to the DOM Without Using `div.innerHTML`?

Appending HTML to the DOM without Using div.innerHTML

When attempting to append a HTML string to the DOM, the typical approach of div.innerHTML = str may seem convenient, but it is often discouraged due to potential security implications. This question explores an alternative solution for appending HTML strings to a specific element.

In this scenario, the task is to append the HTML string

Just some text here

to the

element with the ID test. To achieve this, the preferred approach is to leverage the insertAdjacentHTML method supported by all modern browsers.

Here's how it's done:

div.insertAdjacentHTML('beforeend', str);

Copy after login

The insertAdjacentHTML method takes two parameters:

position: Indicates where to insert the HTML content within the target element. In this case, beforeend adds the content inside the element, after its last child.
HTMLString: The HTML string to be inserted.

Using div.insertAdjacentHTML('beforeend', str) ensures that the HTML string is appended inside the

element, maintaining the DOM structure while avoiding the potential security concerns associated with using innerHTML.
