jQuery X-Editable:根据其他选择字段的值更新选择字段

Question

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:

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>

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);
            }
        });

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

Answer 1

我为此挣扎了一会儿。基本上，最终起作用的是

1. 通过在可编辑成功函数中触发上游可编辑的编辑成功来调节下游可编辑的更新，
2. 将旧的下游可编辑内容替换为自身的克隆，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。

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
