帮助解决此 Rails 代码（选择和 javascript）
我需要在每个选项和 JavaScript 中进行选择，
**select...%>**
<% @buscar.each do |j|%>
<option value="<%= j.cedula_tutor1 %>" onclick="Datos2('j.cedula_tutor1');">
<%= j.cedula_tutor1 %>
</option>
<%end%>
**</select>**
这是我在 Rails 中所做的：
<%=select("cedula_tutor1", "nombre",Tutore.all.collect{|u| [u.cedula_tutor1,u.nombre_tutor1]},{}, {:onchange => "Datos2('j.cedula_tutor1'))"})%>
当然，这不起作用，因为 j.cedula_tutor1 在循环之外。我怎样才能做到呢？我只想调用一个 JavaScript 函数，将 j.cedula_tutor 作为参数。
I need to have a select with options and JavaScript in each one,
**select...%>**
<% @buscar.each do |j|%>
<option value="<%= j.cedula_tutor1 %>" onclick="Datos2('j.cedula_tutor1');">
<%= j.cedula_tutor1 %>
</option>
<%end%>
**</select>**
This is what I have made in rails:
<%=select("cedula_tutor1", "nombre",Tutore.all.collect{|u| [u.cedula_tutor1,u.nombre_tutor1]},{}, {:onchange => "Datos2('j.cedula_tutor1'))"})%>
Of course that doesn't work because the j.cedula_tutor1 is outside the loop. How can I make it? I just want to call a JavaScript function giving the j.cedula_tutor as parameters.

你应该用它来扩展你的循环。或者只是创建一些类变量以通过子实例的
parent属性访问它。或诸如来电者之类的东西。you should extend your loop with it. or just make some class variable to access it via
parentattribute of child instance. or something like caller.
