.html（）jQuery不显示数据

Question

If you choose Men then only the child options for Men should show.

My footer.php:

</div>
<footer class="text-center" id="footer">&copy;Copyright 2015-2016 Shantaus botuquo</footer>
<script>
    function get_child_options(){
        var parentID=jQuery('#parent').val();
        jQuery.ajax({
            url: '/admin/parsers/child_categories.php',
            type: 'POST',
            data: {parentID : parentID},
            succes: function(data){
                jQuery('#child').html(data);
            },
            error:function(){alert("Something gone wrong")},
        })
    }
    jQuery('select[name="parent"]').change(get_child_options);
</script>

My child_categories.php:

</div>
<footer class="text-center" id="footer">&copy;Copyright 2015-2016 Shantaus botuquo</footer>
<script>
    function get_child_options(){
        var parentID=jQuery('#parent').val();
        jQuery.ajax({
            url: '/admin/parsers/child_categories.php',
            type: 'POST',
            data: {parentID : parentID},
            succes: function(data){
                jQuery('#child').html(data);
            },
            error:function(){alert("Something gone wrong")},
        })
    }
    jQuery('select[name="parent"]').change(get_child_options);
</script>

The <option> should come back to the page to here:

div class="form-group col-md-3">
    <label for="child">Child Category*:</label>
    <select class="form-control" name="child" id="child">                   
    </select>
</div>
