如何在数据表中的搜索框行下方添加 div？

Question

我想在数据表的搜索框行下方有一个 div，其中一个子 div 向左浮动，另一个向右浮动，如下所示： <div style="float: left"> left content </div> <div style="float: right"> right content </div>

我的方法来自这个link：https://datatables.net/examples/advanced_init/dom_toolbar.html

$(document).ready(function() {
    $('#example').DataTable( {
        "dom": 'fr<"testdiv">tip'
    } );
    $("div.testdiv").html('<div style="float: left"> left content </div> <div style="float: right"> right content </div>');
} );

这里我有一个问题，我希望 div 出现在与搜索框相同的行中。我怎样才能让它出现在下一行？

Answer 1

你可以这样添加：使用 insertAfter() 功能在搜索框后插入。

$(document).ready(function() {   
  var table = $('#example').DataTable({ 
        select: false,
        dom: '<"testdiv">frtip',
        "columnDefs": [{
            className: "Name", 
            "targets":[0],
            "visible": false,
            "searchable":false
        }]
    });//End of create main table

    $("div.testdiv").html('<div style="float: left"> left content </div> <div style="float: right"> right content </div>').insertAfter( ".dataTables_filter" );
    
    $('#example tbody').on( 'click', 'tr', function () {
   
    alert(table.row( this ).data()[0]);

} );
});

body {
  margin: 2rem;
}
.paginate_button {
  border-radius: 0 !important;
}
.dataTables_wrapper .dataTables_filter {
  width: 100%;
}
.testdiv {
  background: #f0f0f0;
  padding: 10px;
  float: left;
  width: 100%;
}
