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

JavaScript DOM Element Removal Conundrum

When attempting to modify the DOM, it's crucial to address the challenge of adding or removing elements efficiently. In a scenario where an iframe needs to be injected into a webpage, it's essential to first verify its existence and take appropriate action. This poses the question: how to delete the iframe if it's already present?

The provided code snippet attempts to remove the iframe using iframe.removeChild(frameid.childNodes[0]). However, this is an incorrect approach. The removeChild method should be invoked on the parent element, not the child. Therefore, the correct syntax is:

if (frameid) {
    frameid.parentNode.removeChild(frameid);
}

By utilizing this corrected code, the conditional check will determine the presence of the iframe and, if necessary, remove it effectively from the DOM. This ensures that the desired functionality of adding or removing an iframe is achieved seamlessly.
