twitter-bootstrap 切换到移动屏幕大小时自动关闭 Bootstrap 手风琴面板

Auto-close Bootstrap accordion panel when switch to mobile screen size

提问by zimbo000

Using Bootstrap 2.3.2 I have an accordion with a single panel that is open when the page is loaded.

使用 Bootstrap 2.3.2 我有一个带有单个面板的手风琴，在页面加载时打开。

          <div class="accordion" id="refine">
              <div class="accordion-heading">
                <a class="accordion-toggle" data-toggle="collapse" data-parent="#refine" href="#refine-search">
                  Title
                </a>
              </div>
              <div id="refine-search" class="accordion-body collapse in">
                <div class="accordion-inner">
                  Test text....
                </div>
              </div>
          </div>                    

The site is fully responsive. When switching to a mobile screen size [ @media (max-width: 979px) ] I want the accordion panel to close automatically, i.e. effectively I want the div refine-search line to change to "collapse out".

该网站是完全响应。当切换到移动屏幕尺寸 [@media (max-width: 979px)] 时，我希望手风琴面板自动关闭，即实际上我希望 div 优化搜索行更改为“折叠”。

When in mobile mode, the accordion must still work, e.g. the user can click on the accordion heading and the panel will expand hence I do not want duplicate divs to turn the panel off using .hidden-desktop utility classes etc.

在移动模式下，手风琴必须仍然工作，例如，用户可以单击手风琴标题，面板将展开，因此我不希望重复的 div 使用 .hidden-desktop 实用程序类等关闭面板。

I've searched high and low for an answer - can anyone help?

So I eventually figured out how to do this, posting it in case it's of help to anyone.

所以我最终想出了如何做到这一点，发布它以防它对任何人有帮助。

Alter the HTML to:

将 HTML 更改为：

<div class="accordion" id="refine">

    <div class="hidden-phone">
        <div class="accordion-heading">
            <a class="accordion-toggle" data-toggle="collapse" data-parent="#refine" href="#refine-search">
                <legend>
                    <h2>Refine your search</h2></legend>
            </a>
        </div>
    </div>

    <div class="visible-phone">
        <div class="accordion-heading">
            <a class="accordion-toggle" data-toggle="collapse" data-parent="#refine" href="#refine-search">
                <legend>
                    <h2>Refine your search (press to reveal)</h2></legend>
            </a>
        </div>
    </div>

    <div id="refine-search" class="accordion-body collapse in">

        <div class="accordion-inner">

            Test text....
        </div>

    </div>

</div>

And then use this JS in the file.

然后在文件中使用这个JS。

$(window).bind('resize load', function() {
    if ($(this).width() < 767) {
        $('#refine-search').removeClass('in');
        $('#refine-search').addClass('out');
    } else {
        $('#refine-search').removeClass('out');
        $('#refine-search').addClass('in');
    }
});

For Bootstrap 3.x this worked great with no change to their example code:

对于 Bootstrap 3.x，这很有效，无需更改其示例代码：

$(window).bind('resize load', function() {
    if ($(this).width() < 767) {
        $('.collapse').removeClass('in');
        $('.collapse').addClass('out');
    } else {
        $('.collapse').removeClass('out');
        $('.collapse').addClass('in');
    }
});

    if ($(this).width() < 767) {
        $('.collapse').addClass('show');
    } else {
        $('.collapse').removeClass('show');
    }
});

For anyone who comes across this thread: As of 2/17/17, when I came across this thread, both accordion panels were displayed on Desktop and Mobile. The classes "hidden-phone" and "visible-phone" were not showing/hiding depending on the viewport size. I added "hidden-xs" and "visible-xs" to the corresponding divs that wrap the accordion headings and I believe it is now functioning as it was intended to 3 years ago.

对于遇到此线程的任何人：截至 2017 年 2 月 17 日，当我遇到此线程时，桌面和移动设备上都显示了两个手风琴面板。根据视口大小，“隐藏电话”和“可见电话”类未显示/隐藏。我将“hidden-xs”和“visible-xs”添加到包装手风琴标题的相应div中，我相信它现在可以像3年前那样运行。

As rtpHarry explained, you do not need to add and remove the class "out", so I removed it. Other than that I did not make any additional edits.

正如 rtpHarry 解释的那样，您不需要添加和删除“out”类，因此我将其删除。除此之外，我没有做任何额外的编辑。

$(window).bind('resize load', function() {
  if ($(this).width() <= 767) {
    $('#refine-search').removeClass('in');
  } else {
    $('#refine-search').addClass('in');
  }
});
