fnDeleteROW bug

dawidmal22

During erasing a row when you do it first it deletes the row that you wanted but if i delete another row in the same time (withour rerfeshing page ) it deletes different row.


For example we have 5 rows

1
2
3
4
5

I delete 4 is fine
deleting 3 in same time without refreshing - row 3 it deletes 1 or 2 i cant say which one.

I m also facing the same issue.

I've created the 'Actions' column dynamically and inserted 'Delete' icon, and passing the table index.

Script I m using to create the table and column:

[code]
(function () {
App = {};
// delete the row
App.deleteRow = function (index, dbId) {
if(confirm('Do you want to delete: ' + dbId)) {
if(deleteRecordAtServer()) { // make server request
jqdt.fnDeleteRow(index, function (dtSettings, row) {
console.log('Row deleted');
}, true);
}
}
};

var renderActions = function (idCol) {
var id = idCol.aData.id; // get the id
return '';
}

$.fn.dataTableExt.sErrMode = 'throw';
jqdt = $('#dataTable').dataTable( {
bJQueryUI: true,
sPaginationType: 'full_numbers',
aaData: testdata.records,
aoColumns: [
{ mDataProp: 'name', sTitle: 'Name' },
{ mDataProp: 'name', sTitle: 'Name' },
{ mDataProp: 'id', bSortable: false, sWidth: 'auto',
sTitle: 'Actions', fnRender: renderActions }
]
} );

}());
[/code]

And, the test data is:

[code]
testdata = {
"records": [
{"id": "1", "name": "Record 1" },
{"id": "2", "name": "Record 2" },
{"id": "3", "name": "Record 3" },
{"id": "4", "name": "Record 4" },
{"id": "5", "name": "Record 5" }
]
}
[/code]

When I delete for first time (some times, for second time too) correct row is getting deleted. But from then on, some random row is getting deleted.

Is this a bug or will indexes change when a row is deleted? if indexes are changed again, then we've a problem with the 'Delete' link generation!

Thanks,

Seems there is some bug using the row index for the deletion.

Workaround for that is using the cell () node. It is discussed in http://www.datatables.net/forums/discussion/6309/solved-fndeleterow-deleting-wrong-rows#Item_2

I don't think it's a bug. I think you set up your links when the data was in the first state, and your ID's matched the datatable's internal state

after deleting one item, if you don't update your rendered links (refresh the page/table), your row ID's will no longer match for some of the rows.
