js, How to get selector from element

Question

I am no sure whether I made the question title right, but I want to ask a question below

<div title="A"></div>

var a = $([title=A]);

//if I only know a, how can I get what is referring here made a, 
//or command I use can get out put of the referring. 
//This case the out put will be '[title=A]'

I am not asking for a.attr('title');

Your wording is very confusing. Do you mean that you want the selector that was used to retrieve the value that was assigned by jquery to a? — Ted Hopp

Thank you, do you mean the question title does not match the actual question? — Micah

You can use selector property in jQuery object to get the selector that was used.

var a = $('[title=A]');
alert(a.selector);  //will alert [title=A]

DEMO: http://jsfiddle.net/Zz4MW/

Note: Use selector property with caution as it is for internal usage. See Why does the .selector property in jQuery not store a valid selector value? for more information.

That is not reliable--see this thread.

a.get()[0] == a.get(0) == a[0].
