How to Properly Remove an Element from the DOM in JavaScript?

JavaScript DOM: Handling Element Existence and Removal

You're attempting to manage the presence of a DOM element, removing it if it exists and creating it if it's absent. While you've successfully addressed element creation, deleting an existing element seems to be problematic.

To resolve this issue, consider that the removeChild() method should be invoked on the parent of the element to be removed, rather than the element itself. In your case, use this revised code:

<code class="javascript">if (frameid) {
    frameid.parentNode.removeChild(frameid);
}</code>

By executing this modification, the parent node of the "injected_frame" element will be correctly targeted for removal, ensuring that the iframe is effectively deleted when it already exists on the page.
