jQuery X-可编辑 : Update select field based on value of other select field

Question

我正在使用 jquery 的 X-Editable 插件。我有两个选择字段，它们通过 ajax 动态提供数据。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);
            }
        });

我想做的是这样的:当他们更改 $('a.zone') 的值时，我希望 $('a.area') 为重新加载ajax数据。我怎样才能做到这一点？

Answer 1

我为此苦苦挣扎了一段时间。基本上，最终的工作是

1. 通过在可编辑成功函数中触发上游可编辑的编辑成功来调整下游可编辑的更新，
2. 用其自身的克隆替换旧的下游可编辑内容，以摆脱附加的表单(我还没弄清楚如何直接更新)，并且
3. 在替换上调用 editables 函数。

看看下面。

    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
