I'm pretty confused with the behaviour of arrays of strings when I loop them through the jQuery.each() method. Apparently, the strings become jQuery objects inside the callback function. However, I cannot use the this.get() method to obtain the original string; doing so triggers a this.get is not a function error message. I suppose the reason is that it's not a DOM node. I can do $(this).get() but it makes my string become an array (from "foo" to ["f", "o", "o"]).

How can I cast it back to string? I need to get a variable of String type because I pass it to other functions that compare the values among them.

I enclose a self-contained test case (requires Firebug's console):

<!DOCTYPE html>
<html>
<head><title></title>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript"><!--
$(function(){
    var foo = [];
    var $foo = $(foo);

    foo.push("987");
    $foo.push("987");

    foo.push("654");
    $foo.push("654");

    $.each(foo, function(i){
        console.log("foo[%d]: object=%o; value=%s; string=%o", i, this, this, $(this).get()); // this.get() does not exist
    });
    $foo.each(function(i){
        console.log("$foo[%d]: object=%o; value=%s; string=%o", i, this, this, $(this).get()); // this.get() does not exist
    });
});
//--></script>
