您可以创建多个提交按钮并为每个按钮提供不同的值:
You can create multiple submit buttons and provide a different value to each:
<% form_for(something) do |f| %>
..
<%= f.submit 'A' %>
<%= f.submit 'B' %>
..
<% end %>
这将输出:
<input type="submit" value="A" id=".." name="commit" />
<input type="submit" value="B" id=".." name="commit" />
在您的控制器中,提交按钮的值将由参数 commit
标识.检查值以进行所需的处理:
Inside your controller, the submitted button's value will be identified by the parameter commit
. Check the value to do the required processing:
def <controller action>
if params[:commit] == 'A'
# A was pressed
elsif params[:commit] == 'B'
# B was pressed
end
end
但是,请记住,这将您的视图与控制器紧密耦合,这可能不是很理想.
However, remember that this tightly couples your view to the controller which may not be very desirable.
