I've looked around on this list and in a number of books, but nothing
I read helped me figure out how to dump out the content of nodes in a
JQuery select list. I came up with my own technique, which uses good
old fashioned DOM functions to figure out a node’s name and
attributes. There is probably a better way, and I’d welcome
suggestions if you have them.
But for now, I’ll be using the DOM approach employed by the sample
code below.
In a nut-shell, this code uses a JQuery select expression to grab all
nodes that have an id attribute, whose selected attribute is “true”,
and whose name ends in “man”. We iterate through those nodes (actually
only one is found), and dump out its content using DOM functions.

attributes[i].nodeValue
}
}
return attribs
}
var dumpNode = function(node) {
alert("got a node: " + node.nodeName + " with attributes: " +
gatherAttributes(node.attributes) +
" / and inner content = " + $(node).html());
}
alert("HI");
$("input[selected=true][id][name$='man']").each (
function() {
alert("got a match " + $(this).val());
dumpNode(this);
});
});

<input id="man-news" name="man-news" > foo1</input>
<input name="milkman" > foo2</input>
<input id="fetterman" name="new-fetterman" > foo3</input>
<input selected="true" id="letterman" name="new-letterman" > foo3</
input>
<input name="newmilk" > foo4</input>
</body>

any better way ? Please let me know.
Thanks !
