remove() makes variable undefined?

remove() makes variable undefined?

Hello, everyone!

I've been at this for a day. I'm trying to remove rows with a certain data attribute, but there's always a few rows that are left behind

Now I narrowed it down to the .remove().draw() method itself! How weird is that?! But sure enough, if I add the .remove().draw(), all the alerts past a certain point turn null or undefined

       var table = $j('#table_view_subs').DataTable();    

       table.rows().eq(0).filter( function (index) {

                var row = table.row( index );
                var rowdata =;
                alert(rowdata); //suddenly returns undefined

                var data = row.nodes().to$().data();
                alert(JSON.stringify(data)); //suddenly returns null

                var closesttr = table.row( $(this).closest("tr").get(0) );

                closesttr.remove().draw(); //if I comment this, all the alerts show the right info

Have you ever seen this before? What can I be doing wrong?

    Hey @colin,

    Thanks for the tip!
    This is the code that I'm using:,js,console,output

    I'm getting some strange errors in the console. I don't know how to interpret them, tho :/ But this is the code I'm using and it runs! I just doesn't work

    Ended up using this:

    var filteredData = table.rows().eq( 0 ).filter( function ( index, value ) {
        //get the data-attributes from the tr
        var data = table.row( index ).nodes().to$().data();
        if(data['dynamic'] == true){
            return true;
        return false;
        } );
       table.rows( filteredData ).remove();

    Hope it helps someone!
