我有10个实例变量,即:@foo_01, @foo_02, @foo_03, @foo_10, 并且我需要在一个页上显示每个变量的成因,这些结果必须用一个相当长的算法加以展示,我不会复制,过去10次改变变量名称,因为我发现这种说法极其令人厌恶,因此我looking想一种途径,通过算法10次循环,并动态地获取变量,例如这种变数。
<% (1..10).each do |i| %>
<% lengthy algorithm here %>
<%= @foo_i .atribute.value %>
<% end %>
<% end %>
t能成为一阵列,有十个要素? 然后,您可随附@foo.each。
