Jquery DataTables 排除具有特定类的行 [英] Jquery DataTables to exclude rows with a certain class

问题描述

我有一个 HTML 表格，在其中应用了 DataTables 函数.我使用表格的第一行，并将类模板"用作我的模板行.然后选择此格式并使用 JSON 提要填充表中的所有行.问题是 DataTables 提供的分页包括这个隐藏的模板行，所以总是让我的第一页显示的行比所有其他页少 1.

有没有办法排除任何行(其中只有一个)并将类模板"应用于 tr?

解决方案

您可以使用旧的 自定义行过滤器:

$.fn.dataTableExt.afnFiltering.push(函数(oSettings，aData，iDataIndex){var row = oSettings.aoData[iDataIndex].nTr;返回 $(row).hasClass('template') ?假:真；});

即使它是 1.10.x 之前的匈牙利符号，它仍然适用于 DataTable() 实例.

I have an HTML table in which I have applied the DataTables function to. I use the first row of the table with the class 'template' applied as my template row. Then pick this formatting up and populate all the rows in the table using a JSON feed. The problem is that the pagination provided by DataTables includes this hidden template row so always makes my first page display 1 less row than all the others.

Is there a way to exclude any rows (of which there will only be one) with the class 'template' applied to the tr?

            pageLength: 20,
            aLengthMenu: [[20, 40, 60, -1], [20, 40, 60, "All"]],
            aoColumnDefs : [{ "bSortable" : false, "aTargets" : [ "no-sort"     ] }]
        });
    }, 200 );

});

解决方案

You can use the good old custum row filter for this :

$.fn.dataTableExt.afnFiltering.push(
    function( oSettings, aData, iDataIndex ) {
        var row = oSettings.aoData[iDataIndex].nTr;
        return $(row).hasClass('template') ? false : true;
    }
);

Even though it is pre-1.10.x hungarian notation, it still works with DataTable() instances.
