如何在simple_form中生成取消按钮？

Question

I want to generate a cancel button using simple_form....but not quite sure how to do that.

<%= f.button :submit, :class => "btn btn-warning btn-small", :label => "Save Changes" %>
<%= f.button :cancel, :class => "btn btn-inverse btn-small", :label => "Cancel" %>

But the cancel button doesn't work.

How do I get that?

Answer 1

Should this be supported by simple form? I had a quick look at github and did not find anything related.

How about link_to "Cancel", :back ?

Answer 2

You can do it with bootstrap easily.

<button type="submit" class="btn btn-default">Create Plan</button>
<%= link_to "Cancel", :back, {:class=>"btn btn-default"} %>

Answer 3

Using simple_form and erb:

<%= f.submit, 'Save', class: 'btn btn-primary' %>
<%= f.button :button, 'Cancel', type: :reset, class: 'btn btn-none' %>

Doing this does not take you to the previous page, it resets the form to its initial state.

Answer 4

Or since Rails 3:

link_to "Cancel", @foo

where @foo is your new or existing model object. Depending on which it is, this link takes you to either edit or new .

Answer 5

您可以使用<%= button_tag "Cancel", :type => 'reset' %>
