First of all, what i would recommend is to "Get a link to Published Data" as csv, as it is just 1 field so you don't have to parse it. If made this spreadsheet, and make a link with "Get a link to Published Data", this second link will get a csv with just one field in this case. You will be able to get this with the following js code (note i'm using jQuery)

$.ajax("https://docs.google.com/spreadsheet/pub?key=0Auwt3KepmdoudE1iZFVFYmlQclcxbW85YzNZSTYyUHc&single=true&gid=0&range=b5&output=csv").done(function(result){
    alert(result);
});
