jQuery DataTable：在表头上搜索单个列

时间：2016-11-13 07:27:57

标签： javascript jquery datatable datatables

我已按照Individual column searching (text inputs)和Individual column searching (select inputs)上的步骤在jQuery DataTable上使用多个过滤器，并且页脚上有多个过滤器。另一方面，我想将这些过滤器移动到DataTable的标题，但不能将它们水平对齐，如下图所示。有一些例子为Custom filtering - range search，但它们也没有对齐。是否有可能做到这一点？ 

$(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();
            }
        } );
    } );
} );

这里solution您的问题请添加必要的数据表配置。

使用CSS将列过滤器从页脚移动到表头，即仅使用

<style>
tfoot {
     display: table-header-group;
}
</style>

这可以通过CSS实现。

$(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="'+title+' Search" />' );
	} );

	// DataTable
	var table = $('#example').DataTable({
		"paging":   false,
		"info":     false,
		"scrollY": 200,
		"scrollX": true
	});

	// 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();
			}
		} );
	} );
		
} );
<style>
body{border:0}
.dataTables_scroll{position:relative}
.dataTables_scrollHead{margin-bottom:40px;}
.dataTables_scrollFoot{position:absolute; top:38px}
</style>

答案 2 :(得分：0)

此处为数据表中单个列搜索的解决方案。 它还用于使用正则表达式进行多行值搜索：

$('#' + tableId + ' thead tr').clone(true).appendTo('#' + tableId + ' thead');
    $('#' + tableId + ' thead tr:eq(1) th').each(function (i) { // Creating Clone Header for Filter TextBox
        var title = $(this).text();
        if (excludeTitle.indexOf(title.trim()) == -1) { // check table column header to add filter textBox
            $(this).html('<input type="text" id="col' + i + '_filter" class="ClearFilters" placeholder="Search ' + title + '" />');
            $('input', this).on('keyup change', function () {
                if (table.column(i).search() !== this.value) { 
  var sp1 = this.value;
 var regex_check = null;
try { regex_check = new RegExp(sp1);}
  catch (error) { alert('Search parameter is not in correct format.'); return false; }
                    table.column(i).search(sp1, true).draw();
                }
            });
        }
        else {
            $(this).html('');
        }

您可以尝试this DataTables plug-in，尽管界面与您所需要的有所不同，但看起来很符合目的。

答案 4 :(得分：0)

// Setup - add a text input to each footer cell
$('#example thead 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.header() ).on( 'keyup change clear', function () {
        if ( that.search() !== this.value ) {
            that
                .search( this.value )
                .draw();
        }
    } );
} );

答案 5 :(得分：0)

在您的代码中，使用this.header()代替this.footer()

喜欢：

$( 'input', this.header() ).on( 'keyup change', function () {

        // your code
});

希望它会为您服务。

答案 6 :(得分：0)

$(document).ready(function() {
// Setup - add a text input to each footer cell

 var table = $('#example').DataTable( {
    orderCellsTop: true,
    fixedHeader: true
} );;


$("#example thead tr td").each( function ( i ) {
    var select = $('<select><option value=""></option></select>')
        .appendTo( $(this).empty() )
        .on( 'change', function () {
            table.column( i )
                .search( $(this).val() )
                .draw();
        } );

    table.column( i ).data().unique().sort().each( function ( d, j ) {
        select.append( '<option value="'+d+'">'+d+'</option>' )
    } );
});

} );
