DataTables - 在每一行的单元格中显示一个按钮

DataTables - display a button in a cell of every row(DataTables - 在每一行的单元格中显示一个按钮)

问题描述

我使用的是 jQuery DataTables 插件，并且在初始化中我使用的是 "drawCallback" 更改行的外观.

I'm using the jQuery DataTables plugin and within the initialization I'm using the "drawCallback" to make changes to the look of the rows.

我的代码如下:

        "drawCallback": function() {
            table.rows().every( function() {
                var d = this.data();
                var option = this.find('.options');

                if (d.activated) {
                    option.html('<button class="btn btn-mini btn-primary pull-right"> Enabled</button>');
                } else {
                    option.html('<button class="btn btn-mini btn-danger pull-right"> Disabled</button>');
                }
            });

         }

然而 this.find('.options') 部分没有做任何事情.

However the this.find('.options') part isn't doing anything.

基本上我想:

1. 获取当前行
2. 选择我为选项"指定了类名的列
3. 在此处插入与行数据相关的按钮

HTML:

<table id="example">
<thead>
<tr>
   <th></th>
   <th>Last Name</th>
   <th>First Name</th>
   <th>Email</th>
   <th></th>
</tr>
</thead>
</table>

数据表初始化:

var table = $('#example').DataTable( {
   columns: [
        {
            "className":      'center',
            "data":           null,
            "defaultContent": ''
        },
        {
            data: 'last_name'
        },
        {
            data: 'first_name'
        },
        {
            data: 'email'
        },
        {
            "className":      'options',
            "data":           null,
            "defaultContent": ''
        }
    ],

    // ...and so on

最初我有以下有效的代码:

Originally I had the following code which worked:

$('td.options').html('<button class="btn btn-mini btn-primary pull-right"> Enabled</button>');

但这是不加选择的行数据，只是为每一行粘贴了相同的按钮.

but this was indiscriminate of the row data and simply pasted the same button for each row.

推荐答案

使用列.render 选项来定义为单元格生成内容的函数.

Use columns.render option to define a function producing content for the cell.

var table = $('#example').DataTable( {
   columns: [
        {
            "className":      'center',
            "data":           null,
            "defaultContent": ''
        },
        {   "data": 'last_name' },
        {   "data": 'first_name' },
        {   "data": 'email'  },
        {
            "className":      'options',
            "data":           null,
            "render": function(data, type, full, meta){
               if (full.activated) {
                   return '<button class="btn btn-mini btn-primary pull-right"> Enabled</button>';
               } else {
                   return '<button class="btn btn-mini btn-danger pull-right"> Disabled</button>';
               }
            }
        }
    ],

    // ...and so on

});
