How Can I Safely Change the Text of an HTML Element Using JavaScript?

JavaScript: Modifying Element Text

Changing the text content of an HTML element using JavaScript is a common task. One effective method is to utilize the textContent property.

To modify the text of a element with the ID "myspan", use the following code:

document.getElementById("myspan").textContent = "newtext";
Copy after login

This approach is appropriate for modern browsers. However, some older browsers may not recognize textContent. While using innerHTML may seem tempting, it introduces a potential cross-site scripting (XSS) vulnerability, especially if the new content originates from user input.

Therefore, for secure and cross-browser compatibility, it's recommended to use textContent when modifying element text via JavaScript.
