I have a form helper that looks like this:
#_alert.html.haml = add_field_link "Add Email", f, :notification_emails
#application_helper.rb def add_field_link(name, f, association) new_object = f.object.class.reflect_on_association(association).klass.new fields = f.fields_for(association, new_object, :child_index => "new_#{association}") do |builder| render("home/" + association.to_s.singularize + "_fields", :f => builder) end link_to_function(name, h("add_fields(this,'#{association}','#{escape_javascript(fields)}')")) end
:javascript function add_fields(link, association, content) { var new_id = new Date().getTime(); var regexp = new RegExp('new_' + association, 'g'); $(link).prev('ul').append('<li>' + content.replace(regexp, new_id) + '</li>'); }
This line here I had to use ' rather than "/ because otherwise firebug will raise error "unexpected token &":
link_to_function(name, h("add_fields(this,'#{association}','#{escape_javascript(fields)}')"))
but when I click on link its supposed to add a new field with model attributes but doesnt. I look in firebug console and see this:
<a href="#" onclick="add_fields(this,'notification_emails','&lt;li class=\'fields\' style=\'list-style-type: none;\'&gt;\n &lt;input id= \&quot;alert_rule_notification_emails_attributes_new_notification_emails_email \&quot; name=\&quot;alert_rule[notification_emails_attributes] [new_notification_emails][email]\&quot; size=\&quot; 30\&quot; type=\&quot;text\&quot; /&gt;\n &lt;input id= \&quot;alert_rule_notification_emails_attributes_new_notification_emails__destroy \&quot; name=\&quot;alert_rule[notification_emails_attributes] [new_notification_emails][_destroy]\&quot; type=\&quot;hidden \&quot; value=\&quot;false\&quot; /&gt;\n &lt;input id= \&quot;alert_rule_notification_emails_attributes_new_notification_emails__destroy \&quot; name=\&quot;alert_rule[notification_emails_attributes] [new_notification_emails][_destroy]\&quot; type=\&quot;hidden \&quot; value=\&quot;false\&quot; /&gt;&lt;a href= \&quot;#\&quot; onclick=\&quot;remove_fields(this); return false;\&quot;&gt;remove&lt;\/a&gt;\n&lt;\/ li&gt;\n'); return false;">Add Email</a>
Any idea why it looks like this and why the expected behavior doesnt occur?
thanks for response
