flexbox 将换行符添加到剪贴板 [英] flexbox adding newline to clipboard

问题描述

我正在处理使用 flexbox 的布局.到目前为止效果很好，但我在将文本复制到剪贴板时遇到了问题.

显然，使用 flexbox 似乎在每个子节点后添加一个换行符

在下面的演示中可以看到，复制文本LabelMessage"正常工作(粘贴它并保持一行).但是，如果您将 display:flex 添加到容器，则会在复制到剪贴板时在标签"之后添加换行符

这是什么原因造成的?有什么办法可以解决吗?

小提琴:

$('.toggleFlex').on('click', function() {$('.container').toggleClass('flex')})

.container.flex {显示:弹性；红色;}.container.flex 跨度{显示:内容；}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script><span class="toggleFlex">toggle</span><小时><div class="容器"><span class="label">Label</span><span class="label">消息</span>

<小时><textarea></textarea>

这将覆盖由 flex 容器引起的 span 的 display:block :

I'm working with a layout that uses flexbox. Works good so far but I have a problem with copying text to clipboard.

Apparently, using flexbox seems to add a newline character after each child node

It can be seen in the demo below, copying text "LabelMessage" works normally (paste it and it remains one-line). But if you add display:flex to container a newline is added after "Label" upon copying to clipboard

What is causing this? Is there any way around it?

Fiddle: http://jsfiddle.net/zv4mamtm/

$('.toggleFlex').on('click', function() {
  $('.container').toggleClass('flex')
})

.container.flex {
  display: flex;
  color: red;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<span class="toggleFlex">toggle</span>
<hr>
<div class="container">
  <span class="label">Label</span>
  <span class="label">Message</span>
</div>
<hr>
<textarea></textarea>

解决方案

As specified in the previous answer and this post :

In a flex container the child elements ("flex items") are automatically "blockified" ( more details )

depending on your use case, using display: contents can be helpful if you only want to copy / paste text,

see : how display contents works

The easiest way to understand what happens when display: contents is used is to imagine the element’s opening and closing tags being omitted from the markup.

and from the specification :

For the purposes of box generation and layout, the element must be treated as if it had been replaced in the element tree by its contents

( you might want to check the compatibility of this as it won't work in IE and Edge )

$('.toggleFlex').on('click', function() {
  $('.container').toggleClass('flex')
})

.container.flex {
  display: flex;
  color: red;
}

.container.flex span {
  display: contents;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<span class="toggleFlex">toggle</span>
<hr>
<div class="container">
  <span class="label">Label</span>
  <span class="label">Message</span>
</div>
<hr>
<textarea></textarea>

this will override the display:block of the span caused by th flex container :
