数据表显示没有Ajax的子行的信息

问题描述 投票：0回答：2

我试图在不使用ajax的情况下显示子行的额外信息，问题是它运行良好但我希望以列表方式显示多个值。 Something like this

有什么建议？

我正在使用web2py获取数据并填充表格，这是我的尝试：

<script>
            var tabla;
        $(document).ready(function(){
           tabla= $('#tablaGenerica').DataTable( {
            } );

        function format(value) {
              return '<div>Hidden Value: ' + value + '</div>';
          }

        $('#tablaGenerica').on('click', 'td.details-control', function () {
                  var tr = $(this).closest('tr');
                  var row = tabla.row(tr);

                  if (row.child.isShown()) {
                      // This row is already open - close it
                      row.child.hide();
                      tr.removeClass('shown');
                  } else {
                      // Open this row
                      row.child(format(tr.data('child-value'))).show();
                      tr.addClass('shown');
                  }
              });

</script>

<table id="tablaGenerica" class="tablaC table-striped hover cell-border" cellspacing="0" width="100%" >
        <thead>
            <tr>
                 <th></th>
                 <th class="select-filter">Name</th>
                 <th class="select-filter">Age</th>
                 <th class="select-filter">Country</th>
                 <th class="select-filter">Level</th>
            </tr>
        </thead>
            <tbody>
                   {{for person in formList:}}
                 <tr data-child-value="{{=person.Person.salary}}">
                   <td class="details-control"></td>
                   <td>{{=person.Person.name}}</td>
                   <td>{{=person.Person.age}}</td>
                   <td>{{=person.Person.country}}</td>
                   <td>{{=person.Person.level}}</td>
                </tr>
                {{pass}}
            </tbody>
</table>

我建议稍微重构您的应用程序，因为您不需要在HTML服务器端做饭，DataTables可以在客户端为您处理。

您可以简单地准备对象数组，其中每个条目对应于表行，每个对象属性/内部​​数组元素 - 对应于相应的列（或详细信息条目）：

[
    {id: 1, name: 'Clark Kent', age: 32, country: 'USA', level: 'high'},
    {id: 2, name: 'Arthur Curry', age: 31, country: 'USA', level: 'medium'},
    {id: 3, name: 'Barry Allen', age: 24, country: 'USA', level: 'low'}
]

为了将这些对象属性/内部​​数组项链接到表列，您可以使用DataTables选项columns或columnDefs：

$('#tablaGenerica').DataTable({
    ...
    columns: [
        {title: 'ID', data: 'id'},
        {title: 'Name', data: 'name'},
        ...
    ]
});

之后（这是答案的重要部分），为了在子行中显示多个细节，您只需修改format()函数，以便返回子行的HTML标记以及所有必要的详细信息：

const format = data => `
    <div>Age: ${data.age}</div>
    <div>Country: ${data.country}</div>
    <div>Level: ${data.level}</div>
`;

所以，你的案例的完整DEMO可能看起来像那样：

//specify source data
const dataSrc = [
    {id: 1, name: 'Clark Kent', age: 32, country: 'USA', level: 'high'},
    {id: 2, name: 'Arthur Curry', age: 31, country: 'USA', level: 'medium'},
    {id: 3, name: 'Barry Allen', age: 24, country: 'USA', level: 'low'}
];
//initialize DataTables
const dataTable = $('#tablaGenerica').DataTable({
  //specify necessary options to adjust DataTable to your needs
  dom: 't',
  data: dataSrc,
  //specify columns that should be visible initially
  columns: [
    {title: 'ID', data: 'id'},
    {title: 'Name', data: 'name'}
  ]
});
//declare function that renders child row with hidden details
const format = data => `
    <div>Age: ${data.age}</div>
    <div>Country: ${data.country}</div>
    <div>Level: ${data.level}</div>
`;
//attach event listener to row click
$('#tablaGenerica').on('click', 'tr', function(){
  //get clicked row into a variable
  const clickedRow = dataTable.row($(this));
  //show/hide child row
  clickedRow.child.isShown() ? clickedRow.child.hide() : clickedRow.child(format(clickedRow.data())).show();
  //toggle 'shown' class
  $(this).toggleClass('shown');
});
#tablaGenerica tbody tr.even:hover, #tablaGenerica tbody tr.odd:hover{
  cursor: pointer;
  background: lightgray;
}

有一个example给你

/* Formatting function for row details - modify as you need */
function format ( d ) {
    // `d` is the original data object for the row
    return '<table cellpadding="5" cellspacing="0" border="0" style="padding-left:50px;">'+
        '<tr>'+
            '<td>Full name:</td>'+
            '<td>'+d.name+'</td>'+
        '</tr>'+
        '<tr>'+
            '<td>Extension number:</td>'+
            '<td>'+d.extn+'</td>'+
        '</tr>'+
        '<tr>'+
            '<td>Extra info:</td>'+
            '<td>And any further details here (images etc)...</td>'+
        '</tr>'+
    '</table>';
