I have 2 coulmns, ID and Salary. I am linking the salary to google.com, for that I am using fnRowCallback function. But that doesn't seem to work. Where do you think I am going wrong. The jsp is shown above.

    Take a look at columns.data

    @Jamaur: I couldn't relate it with my requirements. Can you tell how to catch columns in a row?

    I have just started learning programming.

  • JamaurJamaur Posts: 85Questions: 9Answers: 0 

    $('#example').dataTable( {
  "columnDefs": [ {
    "targets": 0,
    "data": function ( row, type, val, meta ) {
      if (type === 'set') {
        row.salary= val;
        return;
      }
      else if (type === 'display') {
        return "<a href='google.co.uk'>" +row.salary+ "</a>";
      }
      return row.salary;
    }
  } ]
} );

    Targets refer to the column index

                            row.salary=val;
                        }
                        else if(type==='display'){
                    return "<a href='google.com'>"+row.salary+"</a>";   
                        }
                        }
                    }],
                    ajax : {
                        url: 'hello/data1',
                        dataType:'json',
                        type: 'POST'
                    }
                }
                 );
        });
       </script>

    I am getting undefined in my second column and also it is appending google.com to my url.

    Also,
    what is type==='set' and 'display'?

  • JamaurJamaur Posts: 85Questions: 9Answers: 0

    Are you sure salary (row.salary) is the name of the column? What second column?

    The different types of data requested for the cell:

    Set: The value to be used internally or something of the sort
    Display: The value to be used for display purposes, in your case encase the value in a link
    Filter: The value to be used for Filter purposes
    Sort: The value to be used for Sort purposes

                    "columnDefs":[{
                    "targets":1,
                    "data": function(row,type,val,meta){
                        if(type==='set'){
                            row.salary=val;
                        }
                        else if(type==='display'){
                    return "<a href='google.com'>"+salary+"</a>";   
                        }
                        }
                    }],
                    ajax : {
                        url: 'hello/data1',
                        dataType:'json',
                        type: 'POST'

                    }

                }

                 );
        });

    </script>

    I am sure the name of my second column is salary with small s. Now when I change this, my table is not getting populated. I am really stupid I guess.
