Getting data from JSON-Server to local JQuery

Question

Local HTML and JSON-Server data. Getting the data from JSON-Server and using it in JQuery.

Resolved with help of Kevin B and Sirko. Leaving the JS (JQuery) so it can be coppied in the future.

var i = 0;
var output;

$("#send").click(function(e) {
    $.getJSON("http://localhost:3000/db", function(data) {})
        .done(function(json) {
            $.each(json, function(key, val) {
                output+= '<p>name=' + json[i].name + '</p>';
                i++;
            });
            $("#paragraph").append(output);
        })
        .fail(function(jqxhr, textStatus, error) {
            var err = textStatus + ", " + error;
            console.log("Request Failed: " + err);
        });

});
