数据表中的列排序问题

Question

我正在使用 dataTables Jquery 插件和 twitter 引导程序。当数据不在特定范围内时，我有 HTML 格式的 td 内容以向其中添加弹出框。（具有弹出框的橙色单元格）

现在的问题是，当我对温度列进行排序时，它没有得到正确排序。请注意，我已按降序对 AS2000 的温度进行排序，但只有正常单元格被排序。

我已经像这样初始化了数据表

$('#summaryTable').dataTable({
     "aoColumns":[null,null,{"sType": "num-html"},{"sType": "num-html"}]
});  

普通的td单元格包含以下代码

 <td name="temperature_celsius" class="normal sorting_1"><div><span>23.40</span></div> </td>

橙色背景色的单元格包含以下代码

 <td name="temperature_celsius" class="warning sorting_1"> <div> <span data-container="body" data-trigger="hover" data-toggle="popover" data-placement="bottom" data-title="<strong>Alert</strong>" data-html="true" data-content="<p class='text-danger'>Exceeds range limit 30.0 - 20.0 </p>" data-original-title="" title="">61.0</span><i class="icon icon-exclamation-sign pull-right" style="font-size: 21px;"></i></div></td>

有什么帮助吗？

这里除了日期之外的每个键都是一个设备。设备键包含以下信息数组

   [Temperature,Humidity,IsTemperatureRangeExceeds,IsHumidityRangeExceeds,TemperatureRangeLimit,HumidityRangeLimit]

我正在按照以下方式构建表格

    $.ajax({  
     type : "POST",

     success : function(result) { 

                    obj = JSON.parse(result);             
                    $("#reporttabletbodytempsum").empty();

                    var tablebody = $('#reporttabletbodytempsum');
                    $.each( obj, function( index, value ) { 


                            var convertedDate=value.Date;
                            $.each(value,function(index1,value1){
                               if(index1!="Date"){

                               }        
                            });            
            tablebody.append($('<tr class="reporttable"><td>'+ ++sno +'</td><td>'+convertedDate+'</td>'+sreialloop+'</tr>'));   



 });
$('[data-toggle="popover"]').popover({
    'placement': 'auto',
    trigger: 'hover'
});       

sumTable = $('#summaryTable').dataTable();              

     },   
     error: function(XMLHttpRequest, textStatus, errorThrown) { 
         alert("Status: " + textStatus); alert("Error: " + errorThrown); 
     }      
    }) ;

有没有更好的方法？这样我就可以在没有任何错误的情况下进行排序。

谢谢， 米通

Answer 1

您应该使用mRender 函数来设置您的输出样式。

它只会修改单元格的显示，但会保持底层数据不变，因此可以用于排序和过滤。

    "aoColumns": [null, null, {
      mRender: function(data, type, full) {
        if (data >= 5) {
          return '<div name="temperature_celsius" class="warning sorting_1">' + data + '</div>';
        }
        return '-';
      }
    }, {
      mRender: function(data, type, full) {
        if (data >= 20 && data <= 60) {
          return '<div name="temperature_celsius">' + data + '</div>';
        }
        if (data >= 60) {
          return '<div name="temperature_celsius" class="warning sorting_1">' + data + '</div>';
        }
        return '-';
      }
    }]

返回的 div 的样式由您决定。

这是一个有效的Plunker，带有自定义渲染和完整排序。
