sudo

//find any link with the class nav_home, and that have a # in the href value
//store the value in an array, split it into 2, # and string
//save the string value as a var
//replace the value of the href with the string var

ened up going with this kinda of deal:

$(function(){

//swap out the default permalink addresses with anchor jumps

$("li.nav_home>a"     ).attr("href",      "#home");
$("li.nav_about>a"    ).attr("href",     "#about");
$("li.nav_services>a" ).attr("href",  "#services");
$("li.nav_portfolio>a").attr("href", "#portfolio");
$("li.nav_contact>a"  ).attr("href",   "#contact");

});
