数据表JS通过单列值获取行索引PHP

Question

I'm working on a system of medical transportation. Every day I have around 700 trips, so the table is pretty large. I want the app, after the user adds a trip, the screen is positioned in the newly added trip. (scroll) ,for the user to corroborate the trip successfully added (not my idea, my client wants it that way) . For this, I am sending to the page by parameter the ID of the new trip added. I'm using a function "fnFindCellRowIndexes" that i found on datatables page, but i can't make it work. The column i wait to search in is index 1. Here's my code:

  <script type="text/javascript">
    $(document).ready(function() {

        var table = $('#tabla').DataTable({
            "deferRender": true,
            "language": {
                "url": "include/DataTables/Spanish.json"
            },
            "paging":   false,
            "ordering": false,
            "info":     false,
            "searching": true,
            "columnDefs": [
            {
                "targets": [ 0 ],
                "visible": false,
                "searchable": true
            },
            {
                "targets": [ 1 ],
                "visible": false,
                "searchable": false
            }
            ],
            "stateSave": true
        }); 

         var index = table.fnFindCellRowIndexes( '<?=$idNuevo?>', 1 );
         alert(index);

jQuery.fn.dataTableExt.oApi.fnFindCellRowIndexes = function ( oSettings, sSearch, iColumn )
        {
            var
                i,iLen, j, jLen, val,
                aOut = [], aData,
                columns = oSettings.aoColumns;

            for ( i=0, iLen=oSettings.aoData.length ; i<iLen ; i++ )
            {
                aData = oSettings.aoData[i]._aData;

                if ( iColumn === undefined )
                {
                    for ( j=0, jLen=columns.length ; j<jLen ; j++ )
                    {
                        val = this.fnGetData(i, j);

                        if ( val == sSearch )
                        {
                            aOut.push( i );
                        }
                    }
                }
                else if (this.fnGetData(i, iColumn) == sSearch )
                {
                    aOut.push( i );
                }
            }

            return aOut;
        };

</script>

I'm getting error "fnFindCellRowIndexes is not a function" Can anyone help me? if anyone has any idea to do it in a better way, suggestions are accepted.

Answer 1

1. Declare fnFindCellRowIndexes before you instantiate your dataTable!

2. You must instantiate with dataTable() . fnFindCellRowIndexes is an oldschool none-API plugin. As far as I can see in your code, you should not have problems with that. If you still want to use the new API, you can always use table.api().<api-functions>

3. The PHP variable does not magically echo itself out (no offense :-) - you forget to actually print it :

var index = table.fnFindCellRowIndexes( '<? echo $idNuevo ?>', 1 );

4. Remember that fnFindCellRowIndexes is an equal / == search. If you search for 1 in column #1 it only return columns that hold the value 1 and nothing more, not rows holding 10 , 101 , 1.1 etc.
