jQuery X-Editable：根据其他选择字段的值更新选择字段

I am using the X-Editable plugin for jquery. I have two select fields that are dynamically supplied with data via ajax. This is my code:

我正在使用j -ery的X-Editable插件。我有两个选择字段，通过ajax动态提供数据。这是我的代码：

The fields:

田野：

<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>

And the jQuery:

和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);
            }
        });

What I want to do is this: When they change the value of $('a.zone') I want $('a.area') to reload the ajax data. How can I go about doing this?

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

2 个解决方案

#1

I struggled with this for a bit. Basically, what ended up working was

我有点挣扎。基本上，最终工作的是

1. conditioning the update of my downstream editable on the success of an edit of the upstream editable by triggering it in the editables success function,
2. 通过在editables success函数中触发编辑上游可编辑的成功来调整我的下游可编辑的更新，
3. replacing the old downstream editable with a clone of itself to get rid of the attached form (which I haven't figured out how to update directly), and
4. 用自己的克隆替换旧的下游可编辑，以摆脱附加的表单（我还没想出如何直接更新），以及
5. calling the editables function on the replacement.
6. 在替换上调用editables函数。

Check it out below.

请在下面查看。

    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

I haven't used the plugin before, but glancing at the docs it seems this would work:

我之前没有使用过这个插件，但是看一下这个文档似乎可行：

 $('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();
});
