A string containing a selector expression to match elements against. Given a jQuery object that represents a set of DOM elements, the .children () method allows us to search through the children of these elements in the DOM tree and construct a new jQuery object from the matching elements.

How to retrieve children and grandchildren using jQuery?

You can retrieve children and grandchildren using the * selector. The items will be returned in tree order. You can then get a plain array of elements using jQuery.toArray (): $ (function () { let a = $ ("#wrapper") .find ("*") .addBack () // add the previous match i.e. #wrapper itself to the collection .toArray (); console.log (a); });
