Usage of jQuery .empty() Explained

The .empty() jQuery method removes the children and nodes of the specified elements. All you need to do is specify a selector to match the target elements:

$(selector).empty();

Check the example with the selector defined as <p> below:

$(document).ready(() => {
	$("button").click(() => {
	    $("p").empty();
	});
});

Note: if you make jQuery remove all children elements, nested elements will be deleted as well.

Differences Between jQuery .empty(), .detach() and .remove()
