Question

这个问题是this question的后续行动。

我出于演示目的创建了this JSFiddle。

请注意，当在column1中搜索值时，搜索将按预期进行。但是，当在column2中搜索值时（使用相同的“搜索字段”），data_table.search似乎根本没有被调用，并且找不到相关的行（按F12键在控制台中查看调试信息）。

var data_table = $("#table").DataTable();
var search_term = null;
$.fn.DataTable.ext.search.push(
  function(settings, row, index) {
    if (search_term) {
      search_term = search_term.replace(/[-\/\\^$*+?.()|[\]{}]/g, '\\$&');
      search_term = search_term.toLowerCase();
    }

    console.log(`search_term is ${search_term}`)


    var approver = $(data_table.cell(`:eq(${index})`, ':eq(0)').node()).find('.approver-select').val().toLowerCase();
    console.log(`approver is ${approver}`)

    var approver_match = approver.match(search_term);
    console.log(`approver_match is ${approver_match}`)

    var network_or_group = $(data_table.cell(`:eq(${index})`, ':eq(1)').node()).find('.network-or-group-text').val().toLowerCase();
    console.log(`network_or_group is ${network_or_group}`)

    var network_or_group_match = network_or_group.match(search_term);
    console.log(`network_or_group_match is ${network_or_group_match}`)

    console.log(`approver_match || network_or_group_match || !search_term is ${approver_match || network_or_group_match || !search_term}`)

    console.log('')
    console.log('')

    return approver_match || network_or_group_match || !search_term;
  }
);

$('#table_filter input', data_table.table().container()).on('keyup.DT cut.DT paste.DT input.DT search.DT', event => {
  search_term = $(event.target).val();
  data_table.draw();
});

使用html-input类型的简单方法如下。您定义要定位的列，并在搜索时返回值。它适用于选择和输入。

您不需要检查keyup.DT cut.DT paste.DT input.DT search.DT，因为数据表也会自动为您检查。

$.fn.dataTableExt.ofnSearch['html-input'] = function(value) {
  return $(value).val();
};

var data_table = $("#table").DataTable({
  columnDefs: [{
    "type": "html-input",
    "targets": [0, 1]
  }]
});

<html>

<body>
  <table id="table">
    <thead>
      <th>column1</th>
      <th>column2</th>
    </thead>
    <tbody>
      <tr>
        <td>
          <select class="approver-select">
            <option selected>user1</option>
            <option>user2</option>
          </select>
        </td>
        <td>
          <input class="network-or-group-text" type="text" value="1.1.1.1/32">
        </td>
      </tr>
      <tr>
        <td>
          <select class="approver-select">
            <option>user1</option>
            <option selected>user2</option>
          </select>
        </td>
        <td>
          <input class="network-or-group-text" type="text" value="2.2.2.0/24">
        </td>
      </tr>
    </tbody>
  </table>
</body>

这是更干净的方法，它使用数据表的基本类型属性，而不是像现在那样在搜索时过滤所有数据。
