从JQuery数据表中删除特定的行

jsp

在我的JSP页面上的不同选项卡上,我有三个JQuery DataTables,在其中我希望显示几乎相同的表,并稍加修改。第一个标签上的表格如下:

<table id="firstTable">
<tbody>
    <c:forEach items="${A_List}" varStatus="status" var="alist">
        <tr role="row" id="colorRow" data-user="${alist.D}">
            <td>${alist.A}</td>
            <td>${alist.B}</td
            <td>${alist.C}</td>
            <td>${alist.D}</td>
        </tr>    
    </c:forEach>
</tbody>
</table>

现在,第二个选项卡上的第二个表:

 <table id="secondTable">
    <tbody>
        <c:forEach items="${A_List}" varStatus="status" var="alist">
            <tr role="row" id="colorRow" data-user="${alist.D}">
                <td>${alist.A}</td>
                <td>${alist.B}</td
                <td>${alist.C}</td>
                <td>${alist.D}</td>
            </tr>    
        </c:forEach>
    </tbody>
    </table>

第三张表如下:

<table id="thirdTable">
<tbody>
    <c:forEach items="${A_List}" varStatus="status" var="alist">
        <tr role="row" id="colorRow" data-user="${alist.D}">
            <td>${alist.A}</td>
            <td>${alist.B}</td
            <td>${alist.C}</td>
            <td>${alist.D}</td>
        </tr>    
    </c:forEach>
</tbody>
</table>

现在,在第一张桌子上,我想显示所有内容。在第二个表上,我只想在最后一列中显示以“是”作为其值的行,而在第三个表中,最后一列显示所有以“否”作为其值的行。此外,有些行既没有“是”也没有“否”。它们可以完全忽略。为此,我尝试将其实现为:

  $(function(){
            var firstTable = $('#firstTable').DataTable();
var secondTable = $('#secondTable').DataTable();
var thirdTable = $('#thirdTable').DataTable();

            $.fn.dataTable.ext.search.push(
                      function(settings, data, dataIndex) {
                          return $(firstTable.row(dataIndex).node()).attr('data-user') == 'YES';
                      });
            secondTable.draw();

$.fn.dataTable.ext.search.push(
                      function(settings, data, dataIndex) {
                          return $(secondTable.row(dataIndex).node()).attr('data-user') == 'NO';
                      });
            thirdTable.draw();
        });

但是,这并不符合预期。确实出现了第二个选项卡,但是当我尝试使用搜索选项卡过滤掉所有内容时,第一个和第二个表都被弄乱了。我也试过了fnDeleteRow。也没用。提前致谢!

您需要确保您拥有thead

<div id="first">
    <table id="firstTable">
        <thead>
            <tr>
                <th>One</th>
                <th>Two</th>
                <th>Three</th>
                <th>Yes/No</th>
            </tr>
        </thead>
        <tbody>
            <tr role="row" data-user="Yes">
                <td>1 One</td>
                <td>1 Two</td>
                <td>1 Three</td>
                <td>Yes</td>
            </tr>
            <tr>

                <td>5 Three</td>
                <td>No</td>
            </tr>
        </tbody>
    </table>
</div>

这将停止DataTables的抱怨,然后可以这样创建DataTables:

$(function() {
     var firstTable = $('#firstTable').DataTable();
     var secondTable = $('#secondTable').DataTable({
         "initComplete": function(settings) {
             var api = this.api();
             api.rows().every(function(rowIdx, tableLoop, rowLoop) {
                 var data = this.data();
                 if (data && data[3] !== "Yes") {
                     api.rows(rowIdx).nodes().to$().addClass('remove');
                 }
             });
             api.rows('.remove').remove().draw();
         }
     });
     var thirdTable = $('#thirdTable').DataTable({
         "initComplete": function(settings) {
             var api = this.api();
             api.rows().every(function(rowIdx, tableLoop, rowLoop) {
                 var data = this.data();
                 if (data && data[3] !== "No") {
                     api.rows(rowIdx).nodes().to$().addClass('remove');
                 }
             });
             api.rows('.remove').remove().draw();
         }
     });
 });

在这里工作的JSFiddle。希望能有所帮助(TBH可能有更好的方法-
也许其他人会加入,因为这确实很hackie-总是有一些值得关注的地方……JSFiddle是您的朋友)。
