删除行但总不会更改

标签: jquery datatables

在我的示例中,我尝试使用按钮删除某些行(#Bt_CancTable),我需要自动更新工资列中的页面总数。

如果我更改显示的行数,则动态更新总数,我需要删除已检查的行。

提前谢谢你。



$(document).ready(function() {
    $('#Bt_CancTable').click( function() {
        $('#example').find('tr').each(function () {   
            var row = $(this);
            if (row.find('input[type="checkbox"]').is(':checked') ) {
                console.log('Deleted ROW: '+row.index());
                row.remove();
            };
        });
    }); 
        
    $('#example').DataTable( {
        columnDefs: [ {
            orderable: false,
            targets:   0,
            className: 'dt-body-center',
            render: function (data, type, full, meta){
             return '<input type="checkbox" name="id[]" value="' + $('<div/>').text(data).html() + '">';
         }
        } ],
        select: {
            style:    'os',
            selector: 'td:first-child'
        },
        order: [[ 1, 'asc' ]],
        footerCallback: function ( row, data, start, end, display ) {
                        var api = this.api(), data;

                        // Remove the formatting to get integer data for summation
                        var intVal = function ( i ) {
                            return typeof i === 'string' ?
                                i.replace(/[\$,]/g, '')*0.001 :
                                typeof i === 'number' ?
                                    i : 0;
                        };

                        // Total over all pages
                        total = api
                            .column( 5 )
                            .data()
                            .reduce( function (a, b) {
                                return intVal(a) + intVal(b);
                            }, 0 );

                        // Update footer
                        $( api.column( 5 ).footer() ).html(
                            'K$ '+pageTotal +' ( '+ total +' K$ total)'
                        );
