The :eval method of the ajax() function requires that there is a form field
holding the value to be sent by ajax. So in your view you could just
include in INPUT() helper somewhere on the page and hide it via css. Then
when the "remove row" link is clicked, your could use js to:
- set the input value to the id of the clicked row;
- submit the input value using the :eval method;
Like this:
$('.remove_row').live('click', function(){
var rowid = $(this).attr('id');
$('#helper_input').val(rowid);
ajax('path/to/controller/function'), ['helper_input'], ':eval');
}
In the controller you can remove the item from your list and then do
response.js =
"web2py_component('path/to/view.load','id_of_component_container');"
That will mean that once your controller has run (processed the input you
sent via ajax) the page element you specify will be re-loaded with your
component view.
Hope this helps.
