问题描述

我正在使用DataTables 1.10版。我想通过数字值列出列,当列中显示的值不是数字时。



我可以看到我需要做的是添加一个 data-sort 属性到每个表格单元格。我已经尝试使用 createdRow 方法添加它,但是尽管我可以在HTML中看到属性,但并不是按数字排序。



这是我的代码:

  var data = [
{
'name':'France',
'playing':1000,
'won':11
},
{
'名称':'英格兰',
'playing':1000,
'won':100
},
{
'name':'Germany',
'playing':1000,
'won':109
}
];
$ .each(data,function(i,d){
d.won_percent =(d.won / d.played)* 100;
d.won_display = d.won +' /'+ d.played;
d.won_display + ='(';
d.won_display + = Math.round(d.won_percent * 10)/ 10;
d.won_display + ='%)';
});
var columns = [
{data:name,
title:Country
},
{data:won_display ,
title:游戏赢
},
{data:null,
title:Notes,
defaultContent 这里的其他一些文字,只是为了测试这种反应性的工作
}
];
var html ='< table class =table table-bordered table-hovercellspacing =0width =100%id =myTable>< / table>';
$('#table')。html(html);
$(#myTable)。DataTable({
data:data,
columns:columns,
order:[[1,desc]],
response:true,
paging:false,
searching:false,
createdRow:function(row,data,rowIndex){
$ .each($('td' row),function(colIndex){
if(colIndex === 1){
$(this).attr('data-order',data.won_percent);
}
});
}
});
});

如何让我的表按 d.won_percent的值排序



请注意,我还在构建响应表,这意味着我需要注意使用渲染事件。

解决方案


解决方案 p>

您可以使用正交数据,它是术语jQuery DataTables用于提供不同数据的显示,排序和过滤操作。



还需要显式地列出列数据键入 type:num

  d.won_percent = {
sort:(d.won / d.played)* 100
};
d.won_percent.display =
d.won +'/'+ d.played +
'('+ Math.round(d.won_percent.sort * 10)/ 10 +'%)' ;
});

// ...跳过...

{
数据:won_percent,
标题:游戏赢 ,
type:num,
render:{
_:display,
sort:sort
}
},

I am using DataTables version 1.10. I want to make a column sortable by a numeric value, when the value shown in the column is not numeric.

I can see that what I need to do is add a data-sort attribute to each table cell. I've tried adding this with the createdRow method, but although I can see the attribute in the HTML, it's not sorting numerically.

This is my code:

var data = [
      {
          'name': 'France',
          'played': 1000,
          'won': 11
      },
      {
          'name': 'England',
          'played': 1000,
          'won': 100
      },
      {
          'name': 'Germany',
          'played': 1000,
          'won': 109
      }
  ];
    $.each(data, function(i, d) {
        d.won_percent = (d.won / d.played) * 100;
        d.won_display = d.won + '/' + d.played;
        d.won_display += ' (';
        d.won_display += Math.round(d.won_percent * 10) / 10;
        d.won_display += '%)';
    });
  var columns = [
    { "data": "name",
      "title": "Country"
    },
    { "data": "won_display",
      "title": "Games won"
    },
    { "data": null,
      "title": "Notes",
     "defaultContent": 'Some other text here, included just to test that responsive works'
    }  
  ];
  var html = '<table class="table table-bordered table-hover" cellspacing="0" width="100%" id="myTable"></table>';
  $('#table').html(html);
  $("#myTable").DataTable({
    data: data,
    columns: columns,
    order:[[1, "desc"]],
    responsive: true,
    paging: false,
    searching: false,
    createdRow: function (row, data, rowIndex) {
      $.each($('td', row), function (colIndex) {
        if (colIndex === 1) {
          $(this).attr('data-order', data.won_percent);
        }
      });
    }
  });
});

How can I get my table to sort by the value of d.won_percent?

Note that I'm also building a responsive table, which means that I need to be careful about using render events.

SOLUTION

You can use orthogonal data which is the term jQuery DataTables uses for a way of providing different data for display, sort and filter operations.

Also you need to explicitly state column data type with type: "num".

$.each(data, function (i, d) {
    d.won_percent = {
        sort: (d.won / d.played) * 100
    };
    d.won_percent.display = 
        d.won + '/' + d.played +
        ' (' + Math.round(d.won_percent.sort * 10) / 10 + '%)';
});

// ... skipped ...

{
    "data": "won_percent",
    "title": "Games won",
    "type": "num",
    "render": {
        "_": "display",
        "sort": "sort"
    }
},
