How can I refresh a stored and snapshotted jquery selector variable

Question

I ran yesterday in a problem with a jquery-selector I assigned to a variable and it\'s driving me mad.

Here is a jsfiddle with testcase:

• assign the .el

I also liked @Esailija solution, but seems that this.selector has some bugs with filter. So I modified to my needs, maybe it will be useful to someone

This was for jQuery 1.7.2 didn`t test refresh on filtered snapshots on higher versions

$.fn.refresh = function() { // refresh seletor
    var m = this.selector.match(/\.filter\([.\S+\d?(\,\s2)]*\)/); // catch filter string
    var elems = null;
    if (m != null) { // if no filter, then do the evarage workflow
        var filter = m[0].match(/\([.\S+\d?(\,\s2)]*\)/)[0].replace(/[\(\)']+/g,'');
        this.selector = this.selector.replace(m[0],''); // remove filter from selector
        elems = $(this.selector).filter(filter); // enable filter for it
    } else {
        elems = $(this.selector);
    }
    this.splice(0, this.length);
    this.push.apply( this, elems );
    return this;
};

Code is not so beautiful, but it worked for my filtered selectors.
