I have a table on my site that is automatically generating an id for each table column.

I placed the function call on each line.

How do I pass the id of this <td> per parameter on the function so that I can identify which row I am clicking?

NOTE: I'm using native javascript + angular

Template table:

<table class="table table-hover table-bordered">
                    <thead>
                        <tr>
                            <th>

                            </th>
                            <th>
                                Tipo Ativo
                            </th>
                            <th>
                                Emissor
                            </th>
                            <th>
                                Código
                            </th>
                            <th>
                                Emissão
                            </th>
                            <th>
                                Vencimento
                            </th>
                        </tr>
                    </thead>
                    <tbody>

                            <td id="dado-{{$index + 1}}">

If I understand correctly, this code (explicit, with native js) will help you. Run, and click on all results. The Id will be displayed on the console.

var funcao = function(e){
  console.log(e.target.id);
}

var td = document.getElementsByTagName('td');
for(var i=0; i<td.length; i++){
  td[i].addEventListener('click',funcao)
}
