使用AJAX删除表格行

Question

I'm using AJAX to remove specific rows from jQuery Datatable. These rows have value 0 in the 10th column (if we start counting from 0). Below you can see my code. For some reason, it does not remove any row. I checked the value of aData[10] => it is definetely equal to 0 in some rows.

     $(document).ready(function(){
          $('#newspaper-b').dataTable({
          "sPaginationType":"full_numbers",
          "aaSorting":[[4, "asc"]],
          "aoColumns": [null,null,null,null,null,null,null,null,null,null,
                        {"bSearchable": true, "bVisible": false},null,null],
          "bJQueryUI":true,
          'fnRowCallback': function(nRow, aData, iDisplayIndex, iDisplayIndexFull) {
                if(aData[10]=="0"){
                    $(nRow).remove();
                }
                return nRow;
            }
          });

UPDATE

When I do this:

'fnRowCallback': function(nRow, aData, iDisplayIndex, iDisplayIndexFull) {
                      var r=confirm(aData[10]);
                  if (parseInt(aData[10], 10) === 0) {
                        $(nRow).remove();
                    }
                    return nRow;
                }

...then I can see that one of rows has 0. But when I do this:

'fnRowCallback': function(nRow, aData, iDisplayIndex, iDisplayIndexFull) {
                  if (parseInt(aData[10], 10) === 0) {
var r=confirm(aData[10]);
                        $(nRow).remove();
                    }
                    return nRow;
            }

...then alert JS message (i.e. var r=confirm(aData[10])) does not appear, which means that IF statement returns false. BUT WHY???

This may possibly be a typing issue. Try converting the column value to an integer like this:

if (parseInt(aData[10], 10) === 0) {
    $(nRow).remove();
}
