CSS：截断按钮文本并将图标保留在弹性框中

Question

我正在尝试让按钮显示一些被截断的文本和一个图标。即使文本开始被截断，我也希望该图标存在。

所以问题是当文本被截断时 - 图标也被删除。 我可以通过将图标作为单独的按钮来解决这个问题 - 但这会使键盘导航变得奇怪。

请参阅下面的示例：

.bar {
  display: flex;
}

.item2 {
  border: none;
  background-color: white;
  text-overflow: ellipsis;
  white-space: nowrap;
  overflow: hidden;
}

<nav class="bar">
  <span class="item1">
    TEST
  </span>
  <button type="button" class="item2">
    <span class="item2_text">This is a veeeery long text that we want to overflow so that
    everything is on one line and does not break our content line in two or overflow</span>
    <span class="item2_icon">
      <svg version="1.1" id="Capa_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="18px" height="10px" viewBox="0 0 451.847 451.847" style="enable-background:new 0 0 451.847 451.847;" xml:space="preserve">
        <g>
          <path d="M225.923,354.706c-8.098,0-16.195-3.092-22.369-9.263L9.27,151.157c-12.359-12.359-12.359-32.397,0-44.751
	c12.354-12.354,32.388-12.354,44.748,0l171.905,171.915l171.906-171.909c12.359-12.354,32.391-12.354,44.744,0
	c12.365,12.354,12.365,32.392,0,44.751L248.292,345.449C242.115,351.621,234.018,354.706,225.923,354.706z" />
        </g>
      </svg>
    </span>
  </button>
  <span class="menu">
    Stuff
  </span>
</nav>

我试图将 text-overflow: ellipsis 移动到 item2_text 但它不起作用。 谁能帮帮我？

如果您想采用动态方法，请不要给文本固定宽度，请使用 calc 属性。 首先，将省略号代码移动到跨度而不是将其放在按钮本身上并添加inline-block 属性以使省略号起作用。 然后将项目设置为 100% 并减去图标的宽度（以及一些额外的像素）。

.bar {
  display: flex;
}

.item2 {
  border: none;
  background-color: white;
  overflow: hidden;
}

.item2_text {
  text-overflow: ellipsis;
  white-space: nowrap;
  overflow: hidden;
  display: inline-block;
  width: calc(100% - 25px);
}

<nav class="bar">
  <span class="item1">
    TEST
  </span>
  <button type="button" class="item2">
    <span class="item2_text">This is a veeeery long text that we want to overflow so that
    everything is on one line and does not break our content line in two or overflow</span>
    <span class="item2_icon">
