Question

我的表单中有多个字段，如姓名，姓氏，电子邮件等。我想添加新行/想要删除不需要的行，而不是单个行但是行的整个组合像

1. name "textbox" email "textbox"    "link-addmore"=========== "link-remove" 
2. name "textbox" email "textbox"    "link-addmore"=========== "link-remove" 
.
. 
.

我尝试过rails cast，它适用于非单个字段但不适用于所有字段的组合如果我想要应用整个组合，我应该怎么做

修改 .js文件

function remove_fields(link) {
$(link).previous("input[type=hidden]").value = "1";
$(link).up(".fields").hide();
}

function add_fields(link, association, content) {
var new_id = new Date().getTime();
 var regexp = new RegExp("new_" + association, "g")
$(link).up().insert({
before: content.replace(regexp, new_id)
});
}  



module ApplicationHelper
 def link_to_remove_fields(name, f)
  f.hidden_field(:_destroy) + link_to_function(name, "remove_fields(this)")
  end

 def link_to_add_fields(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(association.to_s.singularize + "_fields", :f => builder)
 end
            link_to_function(name, "add_fields(this, \"#{association}\", \"#{escape_javascript(fields)}\")")
  end
end
