javascript - Ajax 调用无法与 onclick 一起使用

Question

function open_appointment(id)
{
save_method = 'open_appointment';
$('#form_open_appointment')[0].reset(); // reset form on modals
$('.form-group').removeClass('has-error'); // clear error class
$('.help-block').empty(); // clear error string

//Ajax Load data from ajax
$.ajax({
    url : "<?php echo site_url('ReceptionistController/ajax_edit_appointment')?>/" + id,
    type: "GET",
    dataType: "JSON",
    success: function(data)
    {

        $.ajax({
            url : "<?php echo site_url('ReceptionistController/ajax_edit_patient')?>/" +data.ap_patient, 
            type: "GET",
            dataType: "JSON",
            success: function(data)
            {

                $('[name="pt_id"]').val(data.pt_id);
                $('[name="pt_name"]').val(data.pt_name);
                $('[name="pt_dob"]').val(data.pt_dob);
                $('[name="pt_sex"]').val(data.pt_sex);
                $('[name="pt_contact"]').val(data.pt_contact);
                $('[name="pt_email"]').val(data.pt_email);
                $('[name="pt_address"]').val(data.pt_address);
                id=parseInt(id);
                var next_id=id+1;
                var previous_id=id-1;
                //button to call back the function with next id
                $('#next_patient').click(function() {
                alert("next"+next_id);
                open_appointment(next_id);
                });
               //button to call back the function with previous id
                $('#previous_patient').click(function() {
                alert("next"+next_id);
                open_appointment(previous_id);
                });

            },
            error: function (jqXHR, textStatus, errorThrown)
            {
                alert('Failed');

            }
        });

        $('#modal_open_appointment').modal('show'); // show bootstrap modal when complete loaded
        $('.modal-title').text('Open Appointment'); // Set title to Bootstrap modal title

    },
    error: function (jqXHR, textStatus, errorThrown)
    {
        alert('Error get data from ajax');
    }
  });
 }

单击下一个按钮时，该函数将使用下一个 id(例如 id 1)重新加载，但问题是第二次单击下一个按钮时，该函数会加载两次(使用当前 id 和下一个 id 说 id 1 和2)第三次单击它加载三次(加载id说id 1 id 2和id 3)。我希望它只是每次点击时的最后一个 id

尝试

var next_id=1;
var previous_id=1;
function open_appointment(id)
{
save_method = 'open_appointment';
$('#form_open_appointment')[0].reset(); // reset form on modals
$('.form-group').removeClass('has-error'); // clear error class
$('.help-block').empty(); // clear error string

//Ajax Load data from ajax
$.ajax({
    url : "<?php echo site_url('ReceptionistController/ajax_edit_appointment')?>/" + id,
    type: "GET",
    dataType: "JSON",
    success: function(data)
    {

        $.ajax({
            url : "<?php echo site_url('ReceptionistController/ajax_edit_patient')?>/" +data.ap_patient, 
            type: "GET",
            dataType: "JSON",
            success: function(data)
            {

                $('[name="pt_id"]').val(data.pt_id);
                $('[name="pt_name"]').val(data.pt_name);
                $('[name="pt_dob"]').val(data.pt_dob);
                $('[name="pt_sex"]').val(data.pt_sex);
                $('[name="pt_contact"]').val(data.pt_contact);
                $('[name="pt_email"]').val(data.pt_email);
                $('[name="pt_address"]').val(data.pt_address);
                id=parseInt(id);
                next_id=id+1;
                previous_id=id-1;
            },
            error: function (jqXHR, textStatus, errorThrown)
            {
                alert('Failed');

            }
        });

        $('#modal_open_appointment').modal('show'); // show bootstrap modal when complete loaded
        $('.modal-title').text('Open Appointment'); // Set title to Bootstrap modal title

    },
    error: function (jqXHR, textStatus, errorThrown)
    {
        alert('Error get data from ajax');
    }
  });
 }



$(document).on('click','#next_patient',function() {
    alert("next="+next_id);
    open_appointment(next_id);
});
//button to call back the function with previous id
$(document).on('click','#previous_patient',function() {
    alert("previous="+previous_id);
    open_appointment(previous_id);
});
