How does jquery get the ref of an element

as shown below, how can I get the ref in input?
the whole page is processed by the frame. I can"t get the automatically generated ref, directly by attr ("ref"). Sorry, the frame generated rel, not ref, is my negligence.

$("selector").attr("ref")

jq framework can try $(dom). Attr (), native js also has dom.getAttribute ();
if it is delayed loading, you might as well try node simulation loading, or delay loading idea
