jquery: test whether input variable is dom element

Question

I would like to write a jquery function that accepts either a dom element or its id as input:

function myfunction(myinput){
 // pseudocode:
 // if (myinput i         


        

Answer 1

I wonder if a nice ternary would work, something like this

var myID = $(myInput).attr('id') ? $(myInput).attr('id') : myInput;
