如何从javascript隐藏Bootstrap模式？ [英] How to hide Bootstrap modal from javascript?

问题描述

我已经阅读了这里的帖子，Bootstrap网站，以及Googled就像疯了一样 - 但是找不到我确定的答案很简单...

I've read the posts here, the Bootstrap site, and Googled like mad - but can't find what I'm sure is an easy answer...

我有一个Bootstrap模式，我从link_to帮助器打开，如下所示：

I have a Bootstrap modal that I open from a link_to helper like this:

<%= link_to "New Contact", new_contact_path, {remote: true, 'data-toggle' => 'modal', 'data-target' => "#myModal",  class: "btn btn-primary"} %>

在我的 ContactsController.create 操作中，我有代码创建联系然后传递给 create.js.erb 。在 create.js.erb 中，我有一些错误处理代码（ruby和javascript的混合）。如果一切顺利，我想关闭模态。

In my ContactsController.create action, I have code that creates Contact then passes off to create.js.erb. In create.js.erb, I have some error handling code (a mix of ruby and javascript). If everything goes well, I want to close the modal.

这是我遇到麻烦的地方。当一切顺利时，我似乎无法解雇模态。

This is where I'm having trouble. I can't seem to dismiss the modal when all goes well.

我试过 $（'＃myModal'）。modal（'hide'）; 这个有没有效果。我也试过 $（'＃myModal'）。hide（）; 这会导致模态消除但离开背景。

I've tried $('#myModal').modal('hide'); and this has no effect. I've also tried $('#myModal').hide(); which causes the modal to dismiss but leaves the backdrop.

有关如何关闭模态和/或从 create.js.erb 中解除背景的指导？

Any guidance on how to close the modal and/or dismiss the backdrop from within create.js.erb?

编辑

这是myModal的标记：

Here's the markup for myModal:

<div class="modal hide" id="myModal" >
  <div class="modal-header">
    <a class="close" data-dismiss="modal">×</a>
    <h3>Add Contact</h3>
    <div id="errors_notification">
    </div>
  </div>
  <div class="modal-body">
    <%= form_for :contact, url: contacts_path, remote: true do |f| %>  
      <%= f.text_field :first_name, placeholder: "first name" %>
      <%= f.text_field :last_name, placeholder: "last name" %>
      <br>
      <%= f.submit "Save", name: 'save', class: "btn btn-primary" %>
      <a class="close btn" data-dismiss="modal">Cancel</a>
    <% end %>
  </div>
  <div class="modal-footer">
  </div>
</div>

推荐答案

在浏览器窗口中打开模态，使用浏览器的控制台尝试

With the modal open in the browser window, use the browser's console to try

$('#myModal').modal('hide');

如果它有效（并且模态关闭）那么你知道你的关闭Javascript是不是正确地从服务器发送到浏览器。

If it works (and the modal closes) then you know that your close Javascript is not being sent from the server to the browser correctly.

如果它不起作用，那么您需要进一步调查客户端发生了什么。例如，确保没有两个具有相同ID的元素。例如它是否在页面加载后第一次工作但不是第二次？

If it doesn't work then you need to investigate further on the client what is happening. Eg make sure that there aren't two elements with the same id. Eg does it work the first time after page load but not the second time?

浏览器的控制台：firefox的firebug，Chrome或Safari的调试控制台等等。

Browser's console: firebug for firefox, the debugging console for Chrome or Safari, etc.
