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>

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>

$(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>
