javascript - TypeError: Failed to execute 'appendChild' on 'Node': parameter 1 is not of type 'Node'

Javascript - TypeError: Failed to execute 'appendChild' on 'Node': parameter 1 is not of type 'Node'

The error message "TypeError: Failed to execute 'appendChild' on 'Node': parameter 1 is not of type 'Node'" occurs when you try to append an element to the DOM using the appendChild() method, but the parameter passed to appendChild() is not a valid DOM node.

Here are a few possible reasons why you might encounter this error and how to fix it:

  1. Passing a non-DOM element: Ensure that the parameter passed to appendChild() is a valid DOM element. If the parameter is a string or another type of data, you need to create a DOM element from it before appending it to the DOM.

    Example:

    let parentElement = document.getElementById('parent'); let childElement = document.createElement('div'); // Create a new DOM element parentElement.appendChild(childElement);

  2. Passing an undefined or null value: Make sure that the parameter passed to appendChild() is not undefined or null. Check if the variable you are passing contains a valid DOM element.

    Example:

    let parentElement = document.getElementById('parent'); let childElement = document.getElementById('child'); // Check if childElement is not null if (childElement) { parentElement.appendChild(childElement); }

  3. Using appendChild() incorrectly: Ensure that you are using appendChild() correctly. The appendChild() method appends a node to the end of the list of children of a specified parent node. If you are trying to append a node to a parent node that does not exist in the DOM, you will encounter this error.

    Example:

    let parentElement = document.getElementById('nonexistentParent'); // Parent element does not exist let childElement = document.createElement('div'); parentElement.appendChild(childElement); // This will result in an error

By identifying the cause of the error and making the necessary corrections, you can resolve the "TypeError: Failed to execute 'appendChild' on 'Node': parameter 1 is not of type 'Node'" error.
