Question

我正在使用数据表来显示组，阶段和年龄（范围）。现在，包含年龄范围的列按字符串排序，但我希望它按年龄范围排序。因此，年龄10-12在3-8之前，而4-10在4-8之前。

最重要的是，我正在使用YADCF进行累积过滤，其思想是：

您将看到完整的概述。
您选择年龄（范围）
“阶段”列表应仅包含基于先前选择的项目。
仅显示与年龄范围和所选阶段相匹配的组。

问题1

如何实现“年龄”列的排序功能？尝试过各种方法，但没有区别。

问题2

当将“ cumulative_filtering”选项设置为true时，我收到一个JS错误“ TypeError：t.split不是函数”，我想这与data.Age.Min和data.Age.Max。< / p>

HTML

<label for="AgeFilter" class="sr-only">Age</label>
<div id="AgeFilter"></div>

<label for="PhaseFilter" class="sr-only">Phase</label>
<div id="PhaseFilter"></div>

<table id="Table">
<thead>
<tr>
<th>ID</th>
<th>Name</th>
<th>Phase</th>
<th>Age</th>
</tr>
</thead>
</table>

JS

$(function(){
var DT = $('#Table').DataTable( {
    data: [{"Id":0,"Name":"Group 0","Phase":{"Id":1,"Name":"Phase 1"},"Age":{"Min":3,"Max":8}},{"Id":1,"Name":"Group 1","Phase":{"Id":1,"Name":"Phase 1"},"Age":{"Min":3,"Max":8}},{"Id":2,"Name":"Group 2","Phase":{"Id":1,"Name":"Phase 1"},"Age":{"Min":3,"Max":8}},{"Id":3,"Name":"Group 3","Phase":{"Id":1,"Name":"Phase 1"},"Age":{"Min":3,"Max":8}},{"Id":4,"Name":"Group 4","Phase":{"Id":1,"Name":"Phase 1"},"Age":{"Min":3,"Max":8}},{"Id":5,"Name":"Group 5","Phase":{"Id":1,"Name":"Phase 1"},"Age":{"Min":4,"Max":8}},{"Id":6,"Name":"Group 6","Phase":{"Id":1,"Name":"Phase 1"},"Age":{"Min":4,"Max":8}},{"Id":7,"Name":"Group 7","Phase":{"Id":1,"Name":"Phase 1"},"Age":{"Min":4,"Max":8}},{"Id":8,"Name":"Group 8","Phase":{"Id":1,"Name":"Phase 1"},"Age":{"Min":4,"Max":8}},{"Id":9,"Name":"Group 9","Phase":{"Id":1,"Name":"Phase 1"},"Age":{"Min":4,"Max":8}},{"Id":10,"Name":"Group 10","Phase":{"Id":1,"Name":"Phase 1"},"Age":{"Min":4,"Max":8}},{"Id":11,"Name":"Group 11","Phase":{"Id":2,"Name":"Phase 2"},"Age":{"Min":4,"Max":10}},{"Id":12,"Name":"Group 12","Phase":{"Id":2,"Name":"Phase 2"},"Age":{"Min":4,"Max":10}},{"Id":13,"Name":"Group 13","Phase":{"Id":2,"Name":"Phase 2"},"Age":{"Min":4,"Max":10}},{"Id":14,"Name":"Group 14","Phase":{"Id":2,"Name":"Phase 2"},"Age":{"Min":4,"Max":10}},{"Id":15,"Name":"Group 15","Phase":{"Id":2,"Name":"Phase 2"},"Age":{"Min":4,"Max":10}},{"Id":16,"Name":"Group 16","Phase":{"Id":2,"Name":"Phase 2"},"Age":{"Min":10,"Max":12}},{"Id":17,"Name":"Group 17","Phase":{"Id":2,"Name":"Phase 2"},"Age":{"Min":10,"Max":12}},{"Id":18,"Name":"Group 18","Phase":{"Id":2,"Name":"Phase 2"},"Age":{"Min":10,"Max":12}},{"Id":19,"Name":"Group 19","Phase":{"Id":2,"Name":"Phase 2"},"Age":{"Min":10,"Max":12}}],

关于自定义排序功能，我已经尝试过：

sort_as_custom_func: function(one,two) {
    return (one < two);
},

问题是我似乎无法访问Age.Min和Age.Max，其中一个和两个值仍然是字符串，即3-8，所以不了解如何比较这两个值。

Answer 1

关于问题1，您应该实现自己的自定义排序功能sort_as_custom_func（阅读文档）

关于问题2，您需要将列设置为column_data_type: "rendered_html",，并且要实现column_data_render功能，请在related issue中阅读更多内容（尚未记录）

I implemented it for you here

如下

yadcf.init(DT, [
    {
        column_number : 2, 
        filter_container_id: 'PhaseFilter', 
        filter_default_label: 'Phase', 
        //filter_reset_button_text: false, 
        filter_match_mode: 'exact', 
        style_class: 'form-control',
        column_data_type: "rendered_html",
        column_data_render: function (data) {
            return data.Phase.Name;
        }
    },
    {
        column_number : 3, 
        filter_container_id: 'AgeFilter', 
        filter_default_label: 'Age', 
        //filter_reset_button_text: false, 
        filter_match_mode: 'exact', 
        style_class: 'form-control',
        sort_as: 'num',
        column_data_type: "rendered_html",
        column_data_render: function (data) {
            return data.Age.Min + '-' + data.Age.Max;
        }
    }
], {
   cumulative_filtering: true
});

}）;
