How to fix 'Cannot read properties of null (reading 'addEventListener')'
By Tan Lee Published on Dec 18, 2024 392
The `TypeError: Cannot read properties of null (reading 'addEventListener')` error occurs when you try to access a property or call a method, such as `addEventListener`, on a variable that is `null`.
In this case, the error occurs because you're trying to add an event listener to a variable that is null. To fix this, ensure that the variable is properly initialized and points to a valid element before accessing its properties or methods.

// Create a variable and initialize it with a value or elementlet myElement = document.getElementById('myElement');// Check if the element is not null before adding an event listenerif (myElement !== null) { myElement.addEventListener('click', myFunction);} else { console.log("Element not found!");}function myFunction() { console.log("Element clicked!");} |
Make sure to replace 'myElement' with the correct ID or variable name in your code to reference the intended element.
