数据表 - 如何将搜索输入移出表格

时间：2018-04-20 09:06:44

标签： javascript search filter datatables

请帮助我的代码。我已经搜索了我的表的每一列与其他列的关联。我想在表列之外移出具有相同功能的搜索输入。

我发现只有这个： https://datatables.net/reference/api/search() 

var table = $('#example').DataTable();

// #myInput is a <input type="text"> element
$('#myInput').on( 'keyup', function () {
    table.search( this.value ).draw();
} );

但它正在所有表格列中搜索 - 这不是我需要的。

我的工作小提琴：

我需要修改它：

非常感谢您的帮助！

创建了一个简化的示例，但它应该足以让我们了解。

＆＃13;
＆＃13; 
// DataTable
  var table = $('#example').DataTable();

  // Initialize search inputs
  $(".searchField").on("keyup change", function() {
    var input = $(this);
    var colIndex = parseInt(input.attr("column"));
    table.column(colIndex).search(input.val()).draw();
  });
＆＃13; 
.searchField {
  width: 80px;
  padding: 5px;
}
＆＃13;

<div class="container">
  <h3>Search in table columns</h3>
  <select class="searchField" column="0">
    <option value="">Select category</option>
    <option value="A">A</option>
    <option value="B">B</option>
  </select>
  <input type="text" class="searchField" placeholder="Name" column="1">
  <input type="text" class="searchField" placeholder="Quantity" column="2">
  <input type="text" class="searchField" placeholder="Price" column="3">
  <input type="text" class="searchField" placeholder="Total" column="4">
