jQuery X-Editable：根据其他选择字段的值更新选择字段

Question

我正在为 jquery 使用 X-Editable 插件。我有两个通过 ajax 动态提供数据的选择字段。这是我的代码：

字段：

<td class="center">
<a href="#" data-name="'.$res['mid'].'" class="zone">'.$zonename.'</a>
</td>
<td class="center">
<a href="#" data-name="'.$res['mid'].'" class="area" data-zona="'.$zoneuid.'">'.$areaname.'</a>
</td>

还有 jQuery：

$('a.zone').editable({
            type: 'select',
            url: '../admin/callbacks/quickEdit.php?t=zone',
            pk: 1,
            showbuttons: true,
            source: function() {
                var result;
                $.ajax({
                    url: '../admin/callbacks/jsonDataList.php',
                    data: {t: 'zone'},
                    type: 'GET',
                    global: false,
                    async: false,
                    dataType: 'json',
                    success: function(data) {
                        result = data;
                    }
                });
                return result;
            },
            success: function(response, newValue) {
                $(this).parent().siblings('td').children('a.area').data('zona', newValue);
                console.log(response, newValue);
            }
        });
        $('a.area').editable({
            type: 'select',
            pk: 1,
            url: '../admin/callbacks/quickEdit.php?t=area',
            showbuttons: true,
            source: function() {
                var result;
                var zona = $(this).data('zona');
                $.ajax({
                    url: '../admin/callbacks/jsonDataList.php',
                    data: {t: 'area', zone: zona},
                    type: 'GET',
                    global: false,
                    async: false,
                    dataType: 'json',
                    success: function(data) {
                        result = data;
                    }
                });
                return result;
            },
            success: function(response, newValue) {
                console.log(response);
            }
        });

我想要做的是：当他们更改 $('a.zone') 的值时，我希望 $('a.area') 重新加载 ajax 数据。我该怎么做？

Answer 1

我为此挣扎了一会儿。基本上，最终起作用的是

1. 通过在可编辑项成功函数中触发上游可编辑项的编辑成功来调整我的下游可编辑项的更新，
2. 用自己的克隆替换旧的下游可编辑以摆脱附加的表单（我还没有弄清楚如何直接更新），并且
3. 在替换上调用 editables 函数。

在下面查看。

    var editable_triggered_updates = function (changed_element, newValue) { 

        var update_second_editable = function (el_id, newUpstreamValue) {
            var data = { 
                id_upstream_editable: "oldUpstreamValue" 
            };
            if (data[el_id]===undefined) {
                return;
            }

            // IE cache workaround
            var n = new Date().getTime();

            $.getJSON(my_lookup_url, {t:n, my_get_parameter: newUpstreamValue}, function(return_object){

                // Step 2: get rid of old editable form by replacing editable with clone
                $('#id_downstream_editable').replaceWith($('#id_downstream_editable').clone()); 
                $('#id_downstream_editable').attr('data-source', return_object['data-source']);

                // Step 3: call editable on new objects
                $('#id_downstream_editable').editable({ 
                    mode: 'inline',
                    ajaxOptions: {
                        dataType: 'json',
                        sourceCache: 'false'
                    }
                });
            });
        };

        update_second_editable(changed_element.id, newValue);
    };

    !function (triggered_updates) { // editables setup
        $(".editable").editable({
            mode: 'inline', 
            ajaxOptions: {
                dataType: 'json',
                sourceCache: 'false'
            }
            success: function(response, newValue) {
                triggered_updates(this, newValue); // Step 1
            },
        });
    }(editable_triggered_updates || console.log); // Step 1 also

我以前没有使用过该插件，但看了看文档似乎可以：

 $('a.zone').editable({
        type: 'select',
        url: '../admin/callbacks/quickEdit.php?t=zone',
        pk: 1,
        showbuttons: true,
        source: function() {
            var result;
            $.ajax({
                url: '../admin/callbacks/jsonDataList.php',
                data: {t: 'zone'},
                type: 'GET',
                global: false,
                async: false,
                dataType: 'json',
                success: function(data) {
                    result = data;
                }
            });
            return result;
        },
        success: function(response, newValue) {
            $(this).parent().siblings('td').children('a.area').data('zona', newValue);
            console.log(response, newValue);
        }
    });

function loadArea(){
    $('a.area').editable({
        type: 'select',
        pk: 1,
        url: '../admin/callbacks/quickEdit.php?t=area',
        showbuttons: true,
        source: function() {
            var result;
            var zona = $(this).data('zona');
            $.ajax({
                url: '../admin/callbacks/jsonDataList.php',
                data: {t: 'area', zone: zona},
                type: 'GET',
                global: false,
                async: false,
                dataType: 'json',
                success: function(data) {
                    result = data;
                }
            });
            return result;
        },
        success: function(response, newValue) {
            console.log(response);
        }
    });

}

loadArea();

$('a.zone').on('save', function(e, params) {
    loadArea();
});
