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, Jan 31 '13 at 19:20
Thank you, do you mean the question title does not match the actual question? — Micah, Jan 31 '13 at 19:20

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]

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](http://stackoverflow.com/questions/12426622/why-does-the-selector-property-in-jquery-not-store-a-valid-selector-value). – Ted Hopp Jan 31 '13 at 19:24

`a.get()[0]` == `a.get(0)` == `a[0]`. – Joseph Silber Jan 31 '13 at 19:39
