如何用省略号截断长文本但始终在省略号后显示图标

Question

我想要完成的是一个填充其可用父 div 宽度的标题，但如果它的副本不适合 div，它应该用省略号截断。此外，它后面还应有一个图标，该图标不应在截断时消失，但始终显示在省略号之后。

另一个要求是父 div 应该有一个或多个按钮，宽度不特定，位于最右边，但如果调整 div 的大小，它应该截断长标题，允许图标显示在旁边我之前描述的省略号。

在视觉上，我想要的结果如下所示：

到目前为止，我已经实现了以下目标：

/* Helper styles not relevant to the example */

/* Simple flag object from @csswizardry */

.flag {
  display: table;
  width: 100%;
}
.flag .flag__section {
  display: table-cell;
  vertical-align: middle;
}

/* Right float text from bootstrap */

.text-right {
  text-align: right !important;
}


/* Colors for better visibility */

.container {
  background-color: #55606d;
  color: #333;
  padding: 20px;
}
.flag__section--a {
  background-color: #22d398;
}
.flag__section--b {
  background-color: #91c1f8;
}
.fluid-text__icon {
  background-color: #fecb52;
}



/* Styles relevant to the example */

.container {
  max-width: 700px;
}
.fluid-text {
  text-align: left;
}
.fluid-text__inner {
  max-width: 100%;
}
.fluid-text__inner,
.fluid-text__copy {
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
}
.fluid-text__copy,
.fluid-text__icon {
  float: left;
}
.fluid-text__copy {
  padding-right: 5px;
}
.fluid-text__icon {
  margin-top: 30px;
}

/* I'd like to not set explicit max width here */
.title {
  max-width: 600px;
}

<div class='container'>
  <div class='flag'>
    <div class='flag__section flag__section--a fluid-text'>
      <div class='fluid-text__inner'>
        <h1 class='fluid-text__copy title'>
          Lorem ipsum dolor sit amet, consectetur adipisicing elit. Doloremque earum in, voluptas dolorum sit ab modi facere tempora est, sequi molestiae! Commodi vitae sapiente ipsum, nisi facilis impedit aut? Repellendus!
        </h1>
        <span class='fluid-text__icon'>icon</span>
      </div>
    </div>
    <div class='flag__section flag__section--b text-right'>
      <button>ACTION</button>
    </div>
  </div>
</div>

但是，我唯一担心的是我必须明确设置 .title max-width 这是不可扩展的，我想避免它。

没有js有什么办法吗？

Flexbox 可以解决这个问题，我们只需将省略号扩展到 .description div 并进行一些小调整。

* {
  box-sizing: border-box;
}
.parent {
  width: 80%;
  margin: auto;
  display: flex;
  justify-content: space-between;
  align-items: center;
  margin-bottom: 1em;
  padding: .5em;
  border: 1px solid grey;
}
.description {
  display: flex;
  align-items: center;
  white-space: nowrap;
  overflow: hidden;
}
.text {
  flex: 1;
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
}
.icon {
  flex: 0 0 auto;
  background-color: rebeccapurple;
  color: white;
  padding: .5em;
  margin: 0 .25em;
}
.button {
  flex: 0 0 auto;
  background-color: #ccc;
  padding: .5em;
}

<div class="parent">
  <div class="description">
    <span class="text">Lorem sit amet, consectetur adipisicing elit doloremque earum in, voluptas dolorum sit ab modi facere tempora est, sequi molestiae! Commodi vitae sapiente ipsum, nisi facilis impedit aut? Repellendus!</span>
    <span class="icon">I</span>
    <span class="icon">I</span>
    <span class="icon">I</span>
    <span class="icon">I</span>
  </div>
  <div class="button">
    Button
  </div>
</div>

<div class="parent">
  <div class="description">
    <span class="text">Lorem sit amet</span>
    <span class="icon">I</span>
    <span class="icon">I</span>
  </div>
  <div class="button">
    Button
  </div>
</div>

以下使用flex 并依赖于按钮的已知宽度，这看起来像这里的用例。当然，包含的整体可以具有动态大小。图标也可以是任意大小。

.parent {
  width: 400px;
  background-color: yellow;
  display: flex;
  justify-content: space-between;
}

.description {
  width: calc(100% - 50px);
  display: flex;
}

.text {
  display: inline-block;
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
}

.icon {
  display: inline-block;
  background-color: tomato;
}

.button {
  width: 50px;
  background-color: blue;
}

<div class="parent">
  <div class="description">
    <span class="text">Lorem sit amet, consectetur adipisicing elit doloremque earum in, voluptas dolorum sit ab modi facere tempora est, sequi molestiae! Commodi vitae sapiente ipsum, nisi facilis impedit aut? Repellendus!</span>
    <span class="icon">ICON</span>
  </div>
  <div class="button">
    Button
  </div>
</div>

<div class="parent">
  <div class="description">
    <span class="text">Lorem sit amet</span>
    <span class="icon">ICON</span>
  </div>
  <div class="button">
    Button
  </div>
</div>
