Ah, damn you are right...
I havn't looked at the hole code from the livequery plugin... at the
end there is a new init method...

$.fn.ShowSelector = function () { return this.selector; }
console.log($('input.foo').ShowSelector());

yields undefined

There is allready such an attribute
try this:

$("#myID .MyClass mychildren").myfunction() {
  console.log(this.selector); // "#myID .MyClass mychildren"
}

I just released a new version of the HotKeys plug in which was the
reason I needed this new .query property

[Ariel Flesler]

prevObject is internal, you don't need to know about it. Just use
end() instead.

here is the final tweak,
(after adding this modified find method)

query = (this.prevObject && this.prevObject.query) || this[0];

I strongly believe that such property should be added to the main
distro of jQuery.
After all, the idea of find-and-modify approach - one of jQuery
fundamentals.

SG,
thanks for the livequery reference.
it was very helpful,

[Balazs Endresz]

It would be good to know why you need this, I can hardly imagine what
is this good for.
Anyway, here's how you can do it:

jQuery.fn.find=function( selector ) {
  this.query=selector;  //this is the only line you have to modify

  var elems = jQuery.map(this, function(elem){
return jQuery.find( selector, elem );
  });
  return this.pushStack( /[^+>] [^+>]/.test( selector ) ||
selector.indexOf("..") > -1 ?
jQuery.unique( elems ) : elems );
}

Now you can get the query string:
$('body .class').prevObject.query  //->'body .class'
$('body').find('.class').prevObject.prevObject.query  //->'body'
but
$('#id').prevObject.query  //->undefined
$().find('#id').prevObject.query  //->'#id'

[jQuery] Re: How to retrieve jQuery.query?

[Scott González]

That's most of what you need to do, but you also need to reassign the
prototype after overriding the init:

$.prototype.init.prototype = $.prototype;

Check out the last few lines of the livequery plugin to see how to
modify jQuery's init method.

what will you do in case of $('div > p')?

[dabear]

Not sure if I answer your question completly, but doing that test on
each elements tagName should do it

sorry sir,

bu 'this' does not represents the selector expression at any time

I would like to retrieve the selector which initialized the jQuery
instantiation.

for example $('div.foo') returns jQuery object and I want to retrieve
that very 'div.foo' string argument within my code

[jQuery] Re: How to retrieve jQuery.query?

[moester]

I had a similar need.  Wanted to override the default load()
functionality, and needed the original selector.  I tried overriding
jQuery.init to save the passed in selector, eg,

jQuery.fn.extend(jQuery.fn, {

  _init : jQuery.fn.init,
  _selector : '',

  init : function (selector, context) {

 if (typeof of selector == 'string')
   this._selector = selector;

return this._init(selector, context);

  }
})

But couldn't get it to work.  The init method doesn't seem to be
(trivially) extendable.  I think it'll be useful to have, and
hopefully somebody will know the way

the appropriate name is : this

I look through the code and couldn't find a property which contain
this data;

I was thinking that 'query' is the appropriate name for this property

example usage:

$.fn.MyPlugIn = function (){
if (/table|thead|tbody|th|tr|td/.test($.query){
// do the table thing
}
else {
   // do the chair thing ;-)
}
}

$('table').MyPlugIn();
$('div').MyPlugIn
