How can I convert a DOM element to a jQuery element?

I am creating an element with document.createElement().
Now how can I pass it to a function that only takes a Jquery object?

$("#id") 

I can not use it, as the element has not been rendered in the page yet.

Answer

var elm = document.createElement("div");
var jelm = $(elm);//convert to jQuery Element

var htmlElm = jelm[0];//convert to HTML Element
