To me, that seems to be able to add several tags with the same id - I
think that is harmful...

I have a input tag in a form:
<div class="col-xs-4 col-md-4">
        <div id="p_scents">
          <p>
              <label for="p_scnts"><input type="text" id="p_scnt"
size="20" name="p_scnt" value="" placeholder="email address" /></label>
          </p>
        </div>
      </div>
Which gets it's name from the JS function below. However, that name I
can't figure out. I have tried
p_scnt_1 but it comes back undefined. Any ideas what the param name
would be for each sequentially added item?
Here's a working example of the form:
http://jsfiddle.net/jaredwilli/tzpg4/4/
$(function() {
        var scntDiv = $('#p_scents');
        var i = $('#p_scents p').size() + 1;
$('#addScnt').live('click', function() {
                $('<p><label for="p_scnts"><input type="text"
id="p_scnt" size="20" name="p_scnt_' + i +'" value="" placeholder="Input
Value" /></label> <a href="#"
id="remScnt">Remove</a></p>').appendTo(scntDiv);
                i++;
                return false;
        });
$('#remScnt').live('click', function() {
                if( i > 2 ) {
                        $(this).parents('p').remove();
                        i--;
                }
                return false;
        });
});
I don't think it adds the tags with the same name because when I test the
params the first p_scnt comes through as the first value added. If the tags
were being added with the same name I would think that either 1) they would
be string with both values or 2) the last input would override the previous
input. Since param('p_scnt') equals the first value entered neither of
those outcomes are occurring.
