How to Append Text to a Div Element in JavaScript Without Overwriting Existing Content?

Appending Text without Overwriting Existing Content

When working with dynamic web elements, it becomes essential to modify their content without losing previously displayed information. One common scenario is appending text to a

element using AJAX. How can you achieve this without erasing the existing content?

Solution:

The key is to use the = operator instead of the simple assignment operator =. Here's an example:

var div = document.getElementById('divID');

div.innerHTML += 'Extra stuff';

Copy after login

In this code, div.innerHTML represents the current HTML content of the

element. By using =, you append the new text to the existing content instead of replacing it. This ensures that both the original data and the new text are displayed within the

element.

This technique is widely used in web development to dynamically update and enhance content on web pages. It allows you to avoid overwriting precious data and maintain a cohesive user experience.
