From chrome console:
var body = $("body");
=> undefined
body
=> [<body class="ask-page">…</body>]
body.tagName
=> undefined
body.nodeName
=> undefined
So if I have an element reference, how can I know if it's the body?
(JQuery welcome!)

contains DOM API, you can check for the presence of any element in the page (currently in the DOM) quite easily: document. body. contains(YOUR_ELEMENT_HERE);
You can only replace the HTML's body element with PHP if you are outputting the HTML with PHP (changing it before outputting it). PHP works server-side, so once the HTML reaches the client it cannot modify it.
In order to check if an element is present on a webpage, we make use of driver. findElements() method. As we know that driver. findElements() method returns a list of webElements located by the “By Locator” passed as parameter.
Try this comparison with sample usage of plain JavaScript and jQuery:
function isBody(el) {
return document.body === el;
}
isBody(document.getElementById('child').parentElement); // => true
isBody($('#child').parent().get(0)); // => true
