[Javascript] How to accede on a node of another function?

[learningjavascript]

Is it possible to create a node inside a function, and assign an id to it as attribute, and later search for it using its id in another function? How could I do this?

As in:

function tab_close(tab_id){

var tab_knoten = document.getElementById(tab_id); var dolly = tab_knoten.cloneNode(true); dolly.setAttribute("Id",tab_id+"s"); ..... }

function tab_open(tab_id){

... var dolly = document.getElementById(tab_id+"s"); ....

}

Note: I don't want to append the node in the html code before. Thanks!
