form_for通过2个链接提交，当我回到控制器中时，如何告诉我使用了哪个？ [英] form_for being submitting by 2 links, how to I tell which was used when I am back in the controller?

问题描述

我将表单放在一起，但出于设计原因，表单必须通过链接提交。
我发现了如何执行该操作：

I putting a form together, but for design reason the form must be submitted by a link. I found out how to perform that:

= link_to_function "Next >>", "$(this).up('form').submit()"

这样做，我可以创建许多与此相关的问题没有问题。但是我不知道如何区分使用哪个链接将我带回控制器？
我需要根据链接略有不同...

This will do, and I can create many link with this no problem. However I don't know how to distinguish which link was used to bring me back to the controller ? I need to perform slightly different depending on the link...

有什么想法吗？我试图嵌入一些javascript等，但我无法弄明白。

Any idea ? I have tried to embed some javascript, etc. but I could not figure it out.

谢谢，

Alex

推荐答案

= link_to_function "Next >>", "$('#hidden_field').value = 1;$(this).up('form').submit()"
= link_to_function "Next 2 >>", "$('#hidden_field').value = 2;$(this).up('form').submit()"

假设你'重新使用jquery，根据单击的链接将隐藏字段设置为不同的值。毕竟link_to_function的第二个参数只是javascript。

Assuming you're using jquery, set a hidden field to different values depending on which link was clicked. The 2nd parameter to link_to_function is merely javascript, after all.
