Jquery 数据表搜索答案

【问题标题】：Jquery Datatable searchJquery 数据表搜索
【发布时间】：2015-07-05 16:12:13
【问题描述】：

我已经使用 Jquery Datatable 创建了一个数据表。

 $('#mytable').dataTable({
    "pagingType": "simple_numbers",
    "bLengthChange": false,
    "iDisplayLength": 10,
    "aaSorting": [[0, 'asc']],
    "processing": true,
    "serverSide": true,
    "ajax": $('#mytable').data('source'),
    "aoColumnDefs": [
        {'bSortable': false, 'aTargets': [3, 4]}
    ]
});

但是如何搜索表格上显示的数据呢？

【解决方案1】：

var dataTable = $('#mytable').dataTable();

  $('#yourInputFieldID').on('input keyup paste', function () {
    dataTable.fnFilter(this.value);
  });

// 为了防止在输入时提交，我们需要在 keydown 事件中防止 Enter 键的默认行为

$('#yourInputFieldID').keydown(function (event) {
    if (event.keyCode === 13) {
      event.preventDefault();
      return false;
    }
  });

【解决方案2】：

使用 jquery 的数据表搜索试试这个它会提供 no:of 行来显示并且还显示分页和顺序，如 ass dec 所以让我们开始吧。

 <a href="" data-toggle="modal" onclick="Click(this);">click me </a>

现在写div来在我们的页面中显示数据表

  <div id="datatableID"></div>

现在编写jquery函数来从数据库中加载数据

    <script>
    function Click(element) {
      var jqueryVar= $(element).find("input[type='hidden'] 
     [name='htmlfiled']").val();
            $.ajax({
            url : 'your.action',
            type : "post",
            data : {
                "bean name.field name" : jqueryVar
                                },
            success : function(res) {
                $("#datatableID").html(res);

                  $('#complaintstatustable').DataTable({
                        "destroy":true,
                        "pageLength":10

                    }); 
                }

        })
    }
 </script>

使用 jquery 动态搜索数据表

假设您有一个如下所示的数据表，并且您想要过滤 London

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

数据表：

<script type="text/javascript">
$(document).ready(function() {
    var table=$('#example').DataTable();
    var name ='London';
    table.search(name).draw();
} );
</script>

<head>
<link rel="stylesheet" type="text/css" href="jquery.dataTables.min.css">
<script src="jquery-3.5.1.js"></script>
<script src="jquery.dataTables.min.js"></script>
</head>
<body>
<table id="example" class="display" style="width:100%">
