Question

当我设置这样的cookie时，它可以工作：

var now = new Date();
now.setMinutes(now.getMinutes() + 30); 
document.cookie='bla=cats; expires=' + now + ';path=/;'

但是，当我这样做时，它不会：

  <%= f.simple_fields_for :scope do |finalises_s| %>
      <%= finalises_s.simple_fields_for :finalise do |dr| %>

          <div class="row">
            <div class="col-md-3 col-md-offset-1">

              <%= dr.label :draft, 'Would you like to save this draft and finish it later?', class: 'question-project' %>
            </div>
            <div class="col-md-7">
              <%= dr.collection_radio_buttons :draft, [[true, ' Yes, save a draft'], [false, ' No, publish it']], :first, :last, {:item_wrapper_class => 'fixradio'}, {:class => "response-project"} %>
            </div>
          </div>
          <div id="reminder">
            <div class="row">
              <div class="col-md-3 col-md-offset-1">

                <%= dr.label :reminder, 'Would you like a reminder to complete this draft?', class: 'question-project' %>
              </div>
              <div class="col-md-7">
                <%= dr.collection_radio_buttons :reminder, [[true, ' Yes'], [false, ' No']], :first, :last, {:item_wrapper_class => 'fixradio'}, {:class => "response-project"} %>
              </div>
            </div>

所以我想设置一个30分钟到期的cookie，而不是30天。 30天工作正常，后者没有。为什么？如何设置30分钟的cookie？

Answer 1

这将有效：

var now = new Date();
now.setTime(now.getTime() + (30 * 60 * 1000));
document.cookie='bla=cats; expires=' + now + ';path=/;'

Answer 2

您可以尝试：

now.setTime(now.getTime() + (30*60*1000));

和/或之后通过

将Date对象转换为时间字符串

var expires = now.toGMTString();

cookie未按预期设置
