A: You have an extra ) after (event)). 
Try 
$(document).ready(function(){
            $("#create").click(function(event){
                event.preventDefault();
                var name = $("input#name").val();
                var address = $("input#address").val();
                var telephone = $("input#telephone").val();
            $.ajax({
                method: "POST",
                url: "<?php echo base_url();?>index.php/People/person",
                dataType: 'JSON',
                data: {name: name, address: address, telephone: telephone},

                success: function(data){
                    console.log(name, address, telephone);

                }
            });
        });
    });


A: Double syntax error, firstly:
$(document).ready(function) { // has to be (function() {
Secondly:
$("#create").click(function(event)) { // only needs 1 ) behind event
Working code:
$(document).ready(function() {
    $("#create").click(function(event) {
        event.preventDefault();

        var name = $("input#name").val();
        var address = $("input#address").val();
        var telephone = $("input#telephone").val();

        $.ajax({
            method: "POST",
            url: "<?php echo base_url();?>index.php/People/person",
            dataType: 'JSON',
            data: {
                name: name, 
                address: address, 
                telephone: telephone
            },

            success: function(data) {
                console.log(name, address, telephone);
            }
        });
    });
});
