jQuery - datatables, how to get column id

datatables, jquery

Solution

fnGetPosition

Get the array indexes of a particular cell from it's DOM element. Best used in combination with fnGetData().

Input parameters:

nNode : the node you want to find the position of. This my be either a 'TR' row or a 'TD' cell from the table. The return parameter depends on this input.

Return parameter:

int or array [ int, int, int ] : if the node is a table row (TR) then the return value will be an integer with the index of the row in the aoData object. If the node is a table cell (TD) then the return value will be an array with [ aoData index row, column index (discounting hidden rows),column index (including hidden rows) ].

Code example:

$(document).ready(function() {
    $('#example tbody td').click( function () {
        /* Get the position of the current data from the node */
        var aPos = oTable.fnGetPosition( this );

        /* Get the data array for this row */
        var aData = oTable.fnGetData( aPos[0] );

        /* Update the data array and return the value */
        aData[ aPos[1] ] = 'clicked';
        this.innerHTML = 'clicked';
    } );

    /* Init DataTables */
    oTable = $('#example').dataTable();
} );
