将数据表单个列搜索页脚移动到标题

标签： jquery asp.net datatables

现在我正在使用它，以便列搜索作为页脚显示在数据表的底部，搜索功能正常工作。但是，我想将该页脚行追加到标题下方并保留搜索功能。我已经能够将行移动到正确的位置，但是当我执行搜索功能时。我做错了什么？

以搜索为页脚的完整工作脚本：

    $('#divLoading').show();

    $(document).ready(function () {

    $('#<%=ASPxGridView1.ClientID%> tfoot tr td').each(function () {
            var title = $('#<%=ASPxGridView1.ClientID%> thead th').eq($(this).index()).text();
        $(this).html('<input type="text" placeholder="Search ' + title + '" />');
        });

        var dtable = $('#<%=ASPxGridView1.ClientID%>').DataTable({
            colReorder: true, stateSave: true, orderCellsTop: true,
            dom: 'Bfrtilp',
            buttons: [
                {
                    extend: 'colvis',

                },
                {
                    extend: 'csv',
                    text: 'Export',
                    title: 'Applications',
                    exportOptions: {
                        columns: ':visible',                                                                        
                        columns: ':not(:first-child)'
                    }
                }
            ],
            columnDefs: [
                {
                    targets: [7, 8, 9, 10],
                    visible: false
                },
                //{
                //    targets: 0,
                //    orderable: false
                //}
            ],
            "lengthMenu": [[5,100, 500, -1], [5,100, 500, "All"]],
            "scrollX": true

        });

        dtable.columns().every(function () {
            var that = this;

            $('input', this.footer()).on('keyup change', function () {
                if (that.search() !== this.value) {
                    that
                        .search(this.value)
                        .draw();
                }
            });
        });
    $('#divGrid').show();
    $('#divLoading').hide();


    dtable.columns.adjust().draw();

        $('#<%=txtSearch.ClientID%>').focusTextToEnd();
        $('#<%=txtSearch.ClientID%>').keypress(function (e) { if (e.which == 13) { e.preventDefault(); $('#<%=btnSearch.ClientID%>').click(); return false; } });

        $(".buttons-colvis").click(function () {
            if ($(".dt-button-collection").height() > 350) {
                $(".dt-button-collection").css("height", "350px");
                $(".dt-button-collection").css("overflow-y", "visible");
            }
        });
        });

我尝试在＆＃34; $（＆＃39;＃＆lt;％= ASPxGridView1.ClientID％＆gt; tfoot tr td＆＃39;）下添加一行。（function（）{＆＃34;，它会在标题行下面附加一行，但它会中断搜索并说“＃34;找不到匹配的记录＆＃34;。不确定我是将它放在错误的地方还是什么。

添加了一行：

$('#<%=ASPxGridView1.ClientID%> tfoot tr').appendTo('#<%=ASPxGridView1.ClientID%> thead');

没有直接的方法来实现这一目标，

但你可以试试下面的内容。

您只能通过使用CSS相对位置和绝对位置来做到这一点。

请尝试下面的代码，希望对您有所帮助。

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