Ruby on Rails

Hello everybody!

I am displaying a table with data coming from an xml so I'm stepping
through the array and assembling the elements of each row. Each line has
a check_box_tag to select the elements you wish to delete.
Now what I need is to extract each selected two elements, that would be
the identification code and date. Because for delete I need to request
data with these two. The problem is that I am unable to extract two
columns by clicking on check_box_tag. I have a javascript function to
store the selected elements in an array I would also have to change this
function to store in a multidimensional array. My main doubt now is how
to extract these two columns by clicking on check_box_tag. Could someone
help me please?

Loop to display the contents coming from xml:

<% @ag.each do |x| %>
<tr>
<td align="center">
<%= check_box_tag "#{x[0]}", 0, false, :name=>
"chk_del", :onclick => "MultiSelectIDs('chk_del');" %>
</td>
<% x.each do |y| %>
<td align="center"><%= y%></td>
<% end %>
</tr>
<% end %>

<%= text_field_tag :selected_ids, "", :size=>100 %>

javascript funtion:

// Insere na textbox especificada em fieldname os ids selecionados na
listagem através dos checkbox
//(criado para ser utilizado a exportação/impressão do relatório
consolidado)
function MultiSelectIDs(FieldName) {
var selected_ids = new Array()
var objCheckBoxes = document.getElementsByName(FieldName);
for(var i = 0; i < objCheckBoxes.length; i++){
if (objCheckBoxes[i].checked) {
var x = selected_ids.splice(selected_ids.length,0,
objCheckBoxes[i].id);
}
}
document.getElementById('selected_ids').value = selected_ids.join(",
")
};

thank you!

:) Ale
