javascript - 数据表搜索框

Question

我想在我的数据表上进行搜索，但我希望将相应的搜索框定位在某个位置。我遇到了一些代码，我对其进行了更改以说明我的问题(您可以在下面的 fiddle 中查看)。基本上我有四个 div，位于表外，每个 div 都用于搜索特定的列。但是，我很难让它发挥作用。

非常感谢任何帮助!

这是 JSFiddle .

还有代码:

<div>
  <label>Name:</label>
  <input id="Name" type="text">
</div>
<div>
  <label>Position:</label>
  <input id="Position" type="text">
</div>
<div>
  <label>Office:</label>
  <input id="Office" type="text">
</div>
<div>
  <label>Age:</label>
  <input id="Age" type="text">
</div>
<br/>
<br/>
<table id="example" class="display" cellspacing="0" width="100%">
  <thead>

JavaScript:

$(document).ready(function() {
  // Setup - add a text input to each footer cell
  $('#example tfoot th').each(function() {
    var title = $(this).text();
    $(this).html('<input type="text" placeholder="Search ' + title + '" />');
  });
  // DataTable
  var table = $('#example').DataTable();
  // Apply the search
  table.columns().every(function() {
    var that = this;
    $('input', this.footer()).on('keyup change', function() {
      if(that.search() !== this.value) {
        that.search(this.value).draw();
      }
    });
  });
});

CSS:

tfoot input {
  width: 100%;
  padding: 3px;
  box-sizing: border-box;
}

你需要类似 YADCF 的东西DataTables 的过滤插件。它允许您使用外部输入控件过滤列。
