问题描述

是否可以仅对一个数据表应用某个过滤器?我在准备好文档时应用了以下过滤器功能，我不知道这是否是正确的程序，但作为副作用，所有数据表都会受到过滤器的影响.我只想影响 $('#productTable')，但这个选择器似乎没有预期的效果.

Is it possible to apply a certain filter to only one datatable? I have the following filter function that I am applying on document ready, I don't know if this is proper procedure, but as a side effect all dataTables will be affected by the filter. I would Like to affect only the $('#productTable'), but this selector appears to not have the desired effect.

//Filter Function in Stock 
//$('#productTable').
$.fn.dataTableExt.afnFiltering.push(function(oSettings, aData, iDataIndex) {
    var checked = $('#instock').is(':checked');
    var qntStock = 1; 
    var stockCol = 3; 

    if (!checked) {
        return true;
    }
    if (checked && aData[stockCol] > qntStock) {
        return true;
    }

    return false;
 });

是否可以仅对特定表应用过滤器?我该如何做到这一点?

Is it possible to apply a filter only to a particular table? How do I accomplish this?

数据表初始化:

var oTable = $('#productTable').dataTable({
        "aoColumnDefs": [{
            "sClass": "my_class", 
            "aTargets": [4]
            }],
        "bAutoWidth": false,
        "iDisplayLength": 100,
        "fnDrawCallback": function() {
            $("td.my_class").editable(function(value, settings) 
            { 
                return(value);
            }, 
            {
                indicator : 'Save...',
                tooltip   : 'Click to Edit...'
            }
            );
        }
    });

推荐答案

您可以创建一个表数组来进行过滤 - 然后在您的过滤器中检查当前表是否存在于该数组中......类似于:

You could create an array of tables to have the filter - then in your filter check if the current table is present in that array ... something like :

// setup an array of the ids of tables that should be allowed
var allowFilter = ['productTable'];

$.fn.dataTableExt.afnFiltering.push(function(oSettings, aData, iDataIndex) {

    // check if current table is part of the allow list
    if ( $.inArray( oSettings.nTable.getAttribute('id'), allowFilter ) == -1 )
    {
       // if not table should be ignored
       return true;
    }
    var checked = $('#instock').is(':checked');
    var qntStock = 1; 
    var stockCol = 3; 

    if (!checked) {
        return true;
    }
    if (checked && aData[stockCol] > qntStock) {
        return true;
    }

    return false;
});
